• Digium Sangoma as a Frost and Sullivan FROST RADAR™ North American UCaaS Market Leader

  A couple of months ago, I wrote about being selected, again, for the 9th year in a row, to the Gartner UCaaS Magic Quadrant. It never gets old, just like football teams that consistently get to the playoffs! I’m pleased to announce that we’ve also been designed a Leader in the Frost and Sullivant FROST RADAR North American UCaaS Market for this year.

  It’s very nice to honored like this by key analyst companies. It makes all the hard work, by the entire company, mean something. The recognition is nice.

  We know we can’t just sit still and not innovate if we want to keep getting this recognition. The market is continually changing, and the competition changes as well. I mean who would have thought 9 years ago that video meetings and collaboration would be key features in a UCaaS platform now? But they are. Business phone systems are just different now, in a way that benefits the customers.

  Change is still coming though. If you read the report (and the report can be found here on our website), you‘ll see it mentions that “Integrated platforms delivering UCaaS, CCaaS and CPaaS are at the foundation of next-generation business communications solutions”.

  Sangoma certainly agrees with that statement and we have been driving this on our roadmaps for a while. We have or own CCaaS and CPaaS platforms, that are integrated with our UCaaS. And we are using our CPaaS to create apps that augment our UCaaS solution, whether that be with integrations to other software systems, or productivity improvement apps that supplement UCaaS.

  As Elka Popova, VP of Connected Work Research, ICT of Frost and Sullivan says “Sangoma continues to strategically augment and diversify its extensive UCaaS portfolio and partner network, more recently via the acquisition of Star2Star and NetFortris. Sangoma consistently prevails within the industry as a one-stop shop for complete communications solutions, including UCaaS, CPaaS, SD WAN and communications devices.”

  We certainly intend to continue to offer the best one-stop shop cloud communications solutions, intend to continue to innovate, and thus continue to be recognized as leaders!

• Enable Security Kamailio's exec module, SIPVicious still ringing phones and many vulnerabilities
  This new year starts off with a number of RTC security related news and we have some original content to share with you too! In this edition, we cover: Our news: The dangers of using the Kamailio exec module and our pentesting schedule Our news: Updates to the awesome RTC hacking list The Threema weaknesses paper from ETH Zurich Presentations of interest from Blackhat and Nullcon Berlin Receiving calls on your deskphone from SIPVicious - still happening!

• Enable Security Kamailio's exec module considered harmful
  Executive summary (TL;DR) The combination of pseudo-variables and Kamailio’s exec can be risky and may result in code injection. By using special SIP headers and environment variables, it becomes effortless to exploit a vulnerable configuration. We have created a Docker environment to assist readers in reproducing this vulnerability and testing solutions. Protection is tricky and the official documentation may have previously misled developers - we aim to fix that by updating the module’s official documentation.

• Digium Going to ITEXPO and AstriCon

  It’s been a while. For both an in-person AstriCon and an ITEXPO during its “rightful” time in mid-February in southeast Florida. And they are both converging and happening in a few weeks in Fort Lauderdale.

  The last time we had an in-person AstriCon was in 2019. This will be the first one since Covid. We decided to co-locate it with ITEXPO since, at the last AstriCon, we did not have members of the ecosystem (such as phone vendors that support Asterisk and FreePBX). The ecosystem exists in force at ITEXPO, so it made sense to run AstriCon as a co-located event. To register, please go to this link: https://www.itexpo.com/east/astricon.aspx

  And Sangoma will also have a booth at ITEXPO. Since the last time we did a show, we changed our logo, so you will surely notice that. Sangoma has the widest range of business-focused communication services, and we won’t be able to demonstrate all of them. But we will showcase our UCaaS platforms, phones, MSP Services, Open-Source products (Asterisk and FreePBX), and wholesale carrier services (i.e., VoIP Innovations) offerings.

  We’re looking forward to catching up with you, so please stop by our booth (617)!

• ng-voice Webbing selects ng-voice to deploy their fully containerized cloud-native IMS for IoT use cases

  ng-voice will be integrated with Webbing’s offering to provide a flexible and resource-efficient IoT connectivity solution for enterprises

  January 11, 2023 | Berlin, Germany

   

  ng-voice, leading provider of a fully containerized and cloud-native IMS solution for the telecom market, today announced they have been selected by Webbing, a global MVNO connectivity provider for Enterprise Mobility and IoT, to deploy ng-voice’s fully containerized and cloud-native IMS for mission-critical and other IoT use cases. This includes eCall and bCall for automotive, emergency call systems for elevators, highways and alarms, and independent living monitoring wearables for trip or fall assistance. The joint solution will provide connectivity to Webbing’s enterprise customers in a more flexible and resource-efficient way.

  
  The market for IoT solutions is growing rapidly and many new use cases are emerging with the need for voice solutions. 4G/5G Critical IoT and Massive IoT are already around 1.7 bn connections globally and are expected to grow to ~5.0 bn in the next 5 years. To fulfill this market’s requirements, network solutions need to be highly flexible, scalable, new functionalities must be added quickly (update times of days rather than months), and consume minimal resources to reduce costs and make new use cases commercially viable. Cloud-nativity is key to meeting this market’s needs and unlocking the full benefits of connectivity.
  
  ng-voice developed the industry’s first truly cloud-native IMS – the critical component to deploy VoLTE and VoNR. Its key benefits include being cloud-and-infrastructure-agnostic, with highly automated deployment and operation processes, flexibility, and reliability to scale (up and down), standard compliance to 3GPP, and a minimal resource footprint.
  
  Webbing has created connectivity infrastructures and platforms that enable enterprises to leverage exponential growth in connected devices and data. Webbing’s connectivity solutions deliver a global carrier network of 600+ mobile carriers across more than 200 countries that provide the best-of-class for coverage, logistics, processes, costs, security, and other features across one SIM, SKU, Invoice, and Platform. Failover capabilities ensure superior global access to reliable, high-quality internet with low latency. Enterprises receive the benefits of roaming with multiple carrier options in every country, and seamless transition between carriers, while maintaining a local experience with local breakout for low latency on a global scale. With Webbing’s eSIM solution and secured network, enterprises can easily meet regulatory requirements on communication services and data management from states and governments.
  
  According to Yoram Zerahia, CTO at Webbing: “We chose to work with ng-voice because their cloud-native IMS and responsiveness fit perfectly with our portfolio and agile mindset, providing our enterprise customers with secure, reliable, and cost-efficient communication services. It further enhances our voice solution for the automotive industry. Together, we are one step further in helping IoT customers unleash their networks’ full potential.”
  
  For David Bachmann, CEO of ng-voice: “our IMS is ideal for IoT use cases – it is highly automated, resource-efficient, and cost-effective, exactly what IoT use cases are all about. We see high dynamics in this market, and are thrilled to work with a like-minded partner such as Webbing, who is realizing the full potential of cloud-native and fully containerized voice solutions in IoT ”.

• Digium UCaaS Futures Musings Podcast

  In December, I did a podcast with Isha Mukherjee, our Asia-Pac marketing wiz. We talked about a bunch of things, ranging from our new logo, to what happened to UC in 2022, to my thoughts on UC in 2023.

  If you want listen to whole podcast, just go here.

  For this blog, though, I just want to focus on my thoughts for UC in 2023. I encapsulated my thoughts into the term “Smart Business”. This could mean multiple things, such as making your business smarter through using UC. And I certainly see that. In the Frost and Sullivan blog from a few weeks ago, I talked about the integration of contact center, unified communications, and CPaaS. And I certainly see that moving quite far along in 2023, even bringing in some aspects of AI that’s already in the contact center towards UC. And utilizing CPaaS apps to augment the UC system, so that the UC system is “smart” for your business. In other words, it does what you need it to do.

  And that brings us to another meaning of Smart Business, which is doing business in a smart way. I think we’ll see more one-stop shopping with cloud communications in general. If there is a global slowdown, then businesses unfortunately may not be able to keep the same number of employees. There would likely be retrenchment. And this means you need to do business smarter in order to keep the same level of service, and to even grow. One way to do that, is to get your cloud communications from one provider. One bill, one place to talk to, many less headaches. Focus your people on growing the business, not the back-end that runs the business. UCaaS, Contact Center, Augmentation Apps, Collaboration, Video Meetings, and MSP services – all from one vendor, servicing you well. That is Sangoma.

• ng-voice Knowledge sharing sessions | Creativity

  At ng-voice, we come from many different backgrounds and have various experts on our international team. Sharing knowledge helps us improve our skills and become stronger professionals, while also connecting with our colleagues and getting to know more about their experiences.

   

  Every month, one of our colleagues voluntarily shares their expertise with the team in a Knowledge Sharing session.

   

  Last month, our digital marketing specialist Kathrin Hissner hosted a virtual session on creativity and design principles and how we can use our creative skills for problem resolution within our work and everyday lives. 

   

  In this session, she explored what creativity means and how it impacts our mental processes through gamification, to make it easier to grasp complex topics. She also touched upon the rules of the game when it comes to design principles. It is important to understand these design principles as we use them every day, whether it’s on presentations, documentation, or even something more of outreach such as invitation templates. Even though these principles take time to master, keeping simple tips in mind can guide anyone and help them achieve better results in their tasks.

   

  According to Kathrin, “I volunteered to bring my experience in creativity and design to my colleagues because I think this is a topic that can benefit anyone. It is always good to step out of your comfort zone and look at other ways to explore a problem and come up with solutions. I am also very happy to work at a company that fosters this kind of interaction and helps everyone to learn and grow. I hope my colleagues enjoyed the session as much as I enjoyed preparing it, and I am looking forward to the next session.”

• Jitsi Self-hosting a fully-featured Jitsi Meet instance just got as easy as pie

  Hey there Fellow Jitsters!

  Have you ever considered adding telephony to your Jitsi Meet self-hosted instance?

  Up until now you only had the option to run Jigasi and deal with telephony yourself. Many of our users do this every day, but when we asked we learned that there was interest in offloading that part. Could someone else host it?

  

  Today we’re launching a new way to quickly connect to the public telephone network and offer dial-in capabilities to your users without the need for hosting and managing the entire telephony infrastructure: JaaS components. You can give it a try today!

  Are you running Jitsi Meet on a Debian instance or are you using Docker? Either way, you can opt-in for this feature and it will be automatically set up. A new JaaS account will be created for you and you’re good to… call.

  If you’re running Jitsi Meet on Debian all you need to do is to answer ‘Yes’ to this question and you will have dial-in capability on your Jitsi instance.

  

  Note: A Let’s Encrypt certificate is required and the email address used to generate the certificate will be used also for creating your new JaaS account.

  If you’re running Jitsi Meet on Docker you’ll need to set the following variables on your .env file:

  • PUBLIC_URL: the domain were Jitsi Meet runs
  • ENABLE_JAAS_COMPONENTS=1
  • A Let’s Encrypt certificate is required so do enable it too

  

  Now you can restart your setup with `docker-compose up –force-recreate`

   

  An email will be sent to you, asking you to set up a password for the JaaS admin account:

  

  From the JaaS admin console you can manage your account, see the overall activity and upgrade to another plan if needed.

  

  You’re all set up now! Let’s make a phone call! Join a call on your Jitsi Meet instance and notice how the dial-in option becomes available when trying to invite participants. You can now dial-in to one of the phone numbers provided in the list and you’ll be connected to the meeting.

  

  Get started today, a free trial is available! Please check the JaaS components website for details on pricing.

  Jigasi is the first Jitsi component offered as a service, with more to come. Stay tuned!

   

  Your personal meetings team.

• ng-voice ng-voice and Google Cloud launch joint whitepaper: Automation and cloud-nativity

  ng-voice and Google Cloud launch joint whitepaper exploring the automation benefits brought by cloud-native network solutions.

  15 December 2022

   

  Advancements in technology have made it possible for telcos to deploy their services differently. With the importance of efficiency, agility, flexibility, and reliability rising, new technology can allow telcos to keep pace with these changing and increasing demands. 

   

  To explore these challenges and how cloud-native solutions can help telcos to leverage automation and unlock true competitive advantages, ng-voice and Google Cloud launch today a whitepaper called Automation and Cloud-Nativity, which can be downloaded here.

   

  Automation is a frequently used term in technology, and many providers in the wider IT space are leveraging it to improve overall service quality. In fact, more than 30% of organizations foster automation across five or more departments.

   

  For telcos who are often held back by legacy infrastructure, automation could be the answer to modernising operations and streamlining the overall deployment process. 

   

  However, automation alone does not make a modern telco. Indeed, automation must be supported and surrounded by other new technologies and approaches to really see telcos reap their rewards. Cloud-native development is one approach that aligns ideally with automation and as mentioned in this article by Nephio, this approach is critical to realizing the promise of cloud transformation.   

   

  In our whitepaper ‘Automation and cloud-nativity’, we aim to outline how cloud-nativity and automation can be used together to benefit the modern telco, by exploring:

   

  • How automation unlocks the true potential of cloud-nativity
  • The benefits of using cloud-nativity and automation hand-in-hand for both operators and subscribers
  • The importance of automation within a CI/CD pipeline. 

  Download the whitepaper

  Download here

  Get to know more about how ng-voice’s fully containerized and cloud-native IMS, which utilizes automation, can support your organization in delivering VoLTE and VoNR services in https://www.ng-voice.com/fully-containerized-cloud-native-ims/ or contacting our team at  sales@ng-voice.com.

• ng-voice Employee Spotlight | Behnam Hooshiarkashani, VP of Cloud Services

  We at ng-voice are excited to launch our second Employee Spotlight blog. In this series we interview some of our top talents, sharing their experience and insights working at ng-voice. 

  Behnam Hooshiarkashani at ng-voice | Employee Spotlight

  Tell us a bit about yourself, your career before you joined ng-voice, and what is your role at ng-voice now

   

  Before joining ng-voice, I was a DevOps engineer working mostly with Voice over IP (VoIP). I’ve worked with this technology for over 8 years and it’s been more than 3 years now since I joined ng-voice. My journey began as a DevOps engineer then moved on to become DevOps/Cloud team lead and that’s where I started to build this amazing team around me. Now, I’m VP of Cloud Services and my main responsibilities are defining a cloud-native roadmap and being aligned with ng-voice’s product roadmap, along with leading the development of new features and working with partners such as AWS, GKE, Azure, etc. 

   

  Why did you join ng-voice?

   

  The Telecom industry was interesting for me as I was already working as a VoIP engineer.  Secondly, back then, it was a start-up, which allowed me to build something from scratch and see how the company developed and got bigger. It was also very fascinating to see how we can have a 100% containerized and fully cloud-native IMS in the market for the first time, bringing this DevOps mindset to the telecommunication industry. 

   

  What’s the unique part of working here?

   

  For me, it’s actually both the product and the people working here. I believe that our product is very unique in this industry and the reason is that it’s a completely cloud-native product. On the other hand, I like ng-voice’s culture, people, open-feedback mindset, and how we are all growing together. At ng-voice, we are not only thinking of ourselves but thinking of everyone, and how we can support each other while trying to reach one goal together. Also, I love the fact that we care about each and how ng-voice allows each person to grow through a career development roadmap like a two-way relationship.  

   

  What have been your most significant accomplishments at ng-voice?

   

  For me, it’s two things. First, technically, it was onboarding components on Kubernetes and the public cloud, which was not an easy task because telecommunication requirements are very different from normal requirements. We were able to onboard all the components on Kubernetes with the latest technology and use the public cloud for deployment. Also, for me personally, building a team from scratch was honestly one of the biggest achievements in my career. We started with a few people and looking at it now, we have people writing the processes, managing and building it to see how it’s working efficiently along with incorporating methodologies like scrum to ng-voice, and now I see many teams are using this method.  

   

  Any final words?

   

  Final words could be something we use in our team. We have a saying that goes “we work hard together, we are growing together and we will party harder together”. I believe that you cannot have excuses and success at the same time, so you have to choose one.

• Digium Sangoma is Recognized in the Gartner UCaaS Magic Quadrant

  Last week you may have noticed that Gartner, Inc. positioned Sangoma in the 2022 Gartner® Magic Quadrant for Unified Communications as a Service. Sangoma is one of only twelve other companies placed in 2022 and one of six to appear consecutively for the last eight years.

• Jitsi Trust, but verify: introducing user verification

  It’s been a while since we introduced End-to-End Encryption (E2EE) over two years ago. Back then we started with a simple model consisting of a passphrase everyone needed to type and later migrated to a model with randomly generated keys per participant. Each have different characteristic and we ultimately chose to stick with the latter. Today we are introducing a missing piece in the E2EE puzzle: user verification.

  User verification was not previously possible in Jitsi Meet. Just like our core E2EE we are basing our implementation on the Matrix protocol. Matrix’s libolm / vodozemac provide a Short Authentication String (SAS) mechanism implementation which developers can use. They even have great documentation on how it works, thanks Matrix!

  So, how does it work?

  First, you’d gather in a meeting and turn E2EE on.

  

  Now you’ll see a new option for each participant in their tile menu that allows you to verify them:

  

  After choosing to verify a user a dialog will open with a list of emojis:

  .

  Wait what? Emoji? These emojis conform the SAS. They have been carefully chosen to avoid ambiguity and make the process more user friendly than comparing random numbers. You can find more information in the Matrix spec.  You must verbally compare them with the other participant and if they match, mark it as verified.

  Once a user is verified this will be reflected in the user information tooltip:

  

  At this point you can be sure that not only your data is encrypted end-to-end, but also that there is no man-in-the-middle (MITM) attach happening.

  Availability

  User verification is currently available in Jitsi Meet master and deployed in beta. It will be part of the next stable release, but expect more improvements specially in the UX front.

  Thanks

  We’d like to thank Robertas Maleckas (ETH Zurich), Prof. Kenny Paterson (ETH Zurich) and Prof. Martin Albrecht (Royal Holloway, University of London) for their work researching Jitsi Meet’s E2EE and encouragement, and Matrix for their tools, which make implementing E2EE a much better experience.

  Please note that we still consider our E2EE experimental and are still working on improvements. Please make sure you check out our post on how end-to-end encryption in general does NOT offer a meaningful level of trust and protection when it comes to modern meetings services.

• Jitsi Introducing whiteboards in Jitsi Meet

  Trying to explain something to someone and they just don’t get it? If an image is worth a thousand words how about a diagram? Today we’re excited to announce the availability of whiteboards in Jitsi Meet – the missing piece for all those seeking an educational meeting solution and not only!

  

  We decided to stand in the shoulders of giants on this one. The core implementation comes from Excalidraw, an excellent whiteboarding piece of software, which is Open Source, of course. We made some tweaks and adjustments to have it fit in with our vision. We seek to provide an easy to use feature that enables participants to share ideas and brainstorm without having to seek a third party solution. From now on, meeting moderators can open a whiteboard and have everyone in the call sketch away.

  

  The interface supports a number of tools and settings that keep the collaboration interesting and effective. During a meeting, changes that a participant makes locally via the whiteboard are sent to a server to then distribute those updates only to devices of other participants in the meeting. The whiteboard content can be exported as a png or svg at any time during the meeting, so all that hard work doesn’t go to waste.

  

  If you’re using meet.jit.si, you can go ahead and play with the whiteboard in your meetings right away! For those self-hosting, it can be enabled from the config file, and you’ll need to deploy this simple backend.

  As you might already know, we’re firm believers in the power of Open Source, we seek to collaborate with other communities to build solutions everyone can use and we’re excited to bring more to this feature in the future!

  Your personal meetings team.

• Digium Multi-Location UCaaS and Multi-Location Connectivity Services

  Sangoma is very proud and honored to be able to service multi-location businesses with our UCaaS system and MSP services. A common dialing plan among the different physical businesses, physical phones that are tightly tied to the UC system, mobile and desktop clients to augment the desk phone, and having a CPaaS system that can enable multi-location business unique requirements to be added to our UCaaS solution has enabled Sangoma to service these businesses well with our UCaaS solutions.

  Beyond UCaaS, though, Sangoma, through its acquisition of NetFortris, now offers connectivity and security services that can be tailored to bring the best connectivity solution to the needs of the overall multi-location business and each of the specific physical buildings. It is hard to manage what is the best connectivity solution, which provider to get it all from, all the different bills, etc. That’s understandable, for sure. The IT department needs to be expert at everything, and that’s downright impossible.

  Someone like Sangoma can determine the best price, the best type of connectivity solution, and the best provider for each location and manage the network for you. You likely do not need the same bandwidth for each building, and the network provider may most likely offer a different economical service all around. Let someone else figure that all out for you and take care of all that for you.

  As your UCaaS provider, it makes sense to get all this from us. We understand the networks, and we’re monitoring the UCaaS anyway, so why not have us manage and monitor your internet connectivity as well?

  And we can also offer you SD-WAN services with this connectivity so that you can get the most efficient routing, a more stable internet (because of the use of multiple connections), and cost savings. And, of course, monitoring by Sangoma. Learn more about our MSP services here.

• Digium As a Voice Service Provider, How Has the FCC’s Updated Deadline on STIR/SHAKEN Compliance Affected Your Business?

  A few months ago, the FCC released a public notice reminding non-facilities-based “small voice service providers”, that they must implement the STIR/SHAKEN caller ID authentication framework in their Internet Protocol networks no later than June 30, 2022.

  Is this a surprise to you? Well perhaps, considering a 2 year extension was granted to small VPS (those with 100,000 or fewer voice access lines) from the original deadline of June 30th, 2021. So why the sudden change in deadline? What happened was an overwhelming amount of robocalls were observed to be originating from these small VSP from the time that deadline was announced, so much so, the FCC decided to cut the extension by 1 year, significantly moving up the deadline.

  In summary, as a small voice service provider you are no longer subject to a two year extension and must update your certifications and associated filings in the Robocal Mitigation Database (RMD) and implement the authentication framework by June 30, 2022 (which of course has passed at this point in time) or be subject to ”appropriate enforcement action” by the FCC.

  We know that it’s a lot of work, time, and money spent to become compliant. To implement STIR/SHAKEN into your voice network, you’ll likely need to provision a cost-prohibitive session border controller (SBC) or a SIP proxy, which can significantly alter the way you route traffic to your partners. This can create unexpected consequences for you, such as billing, for instance, not to mention the network maintenance and monitoring that’s required for these new points of failure.

  The deadline for compliance has already passed for non-facilities-based providers. Don’t risk waiting for the FCC to contact you and be put under extreme pressure. We have a Zero-maintenance call signing solution for you!

  VI Communication Services’ Call Signing Services help you become compliant, simply by sending your phone calls to our voice network. On our side, we will provision a dedicated server to host your unique certificate and sign calls on your behalf, using the attestation rules that you yourself configured. That’s all! No additional hardware or network maintenance required. We take care of everything for you so that you can focus on running your business. View our product slick.

• ng-voice Placing cloud-native solutions at the heart of private network deployments

  Private networks are steadily gaining ground as operators, enterprises and private providers set their sights on the opportunities cloud-native solutions bring about. Having a dedicated private network brings with it a new realm of possibilities, underpinned by enhanced connectivity. Add to this, the prospect of new revenue generation through better solutions, products, or offerings by the operator, enterprise, or private network provider, and arguably private networks could have several value-added benefits. 

   

  But deploying a successful private network is no easy feat—it requires the right solutions, both at the core of the network, and at the edge; the right partners, who embrace the same ways of working and strive towards a common goal; and importantly, the right application or use case. 

   

  At ng-voice, we believe that the key to private network success lies in embracing cloud-native principles. A private network—by definition—is there to give the end customer greater flexibility and agility over their connectivity solution, enabling them to push the limits of their organization and embrace new technologies such as Internet of Things (IoT) and Artificial Intelligence (AI) to increase their productivity. Moving to cloud-native principles when building and deploying a private network will help operators, enterprises, and private network operators enabling this agility and their end-customers to benefit from the many opportunities set to be unlocked by private networking.

   

  So what do these principles look like?

  First, cloud-nativity is about being cloud-agnostic. Solutions should be deployable on any infrastructure, whether private (bare metal) or public cloud. Second, solutions should embrace a CI/CD approach whereby automation is implemented throughout integration, delivery, and deployment. Third, cloud-native solutions must be scalable and adapt capacity loads accordingly, as well as provide load balancing and service discovery.

   

  Finally, continuing to put automation at the heart of cloud-nativity, such solutions must be self-healing to identify and replace failed components to maximize and maintain service availability at all times. 

   

  But cloud-nativity isn’t simply a set of principles, it’s also a culture, and a mindset. It must be embraced across the entire organization, across entire teams. In a private network scenario, where multiple partners come together to deploy a single solution, being aligned on cloud-nativity principles can bring significant benefits to the end solution and end customer.

   

  An IMS core fit for purpose

  By embracing the principles of cloud-nativity and containerization, our fully containerized cloud-native IMS solution brings to private network deployments greater scalability, being able to scale resources up or down, according to changing needs and requirements. In addition, our solution delivers increased efficiency thanks to the automation embedded in the delivery of our voice services—human intervention is significantly reduced therefore reducing the risk of disruption, and the management of voice applications is made easier and quicker.

   

  Finally, our solution is also more cost-effective thanks to our deployment model and use of cloud-native technologies. For private network deployments, in which voice is still a key requirement, being able to make cost-savings without compromising on the quality of service will be an important factor in selecting the right partner. 

   

  To find out more about ng-voice and how its fully containerized cloud-native IMS solution could be the ideal choice for your private network deployment, write to sales@ng-voice.com visit our website, or follow us on LinkedIn to know more about what we do.

• WebRTC Hacks Revealing mediasoup’s core ingredients: Q&A with Iñaki Baz Castillo
  

  I interviewed mediasoup’s co-founder, Iñaki Baz Castillo, about how the project got started, what makes it different, their recent Rust support, and how he maintains a developer community there despite the project’s relative unapproachability. mediasoup was one of the second-generation Selective Forwarding Units (SFUs). This second generation emerged to incorporate different approaches or address different use cases a few years after the first generation of SFUs came to market. mediasoup was and is different. It is node.js-based, built as a library to be part of a serve app, and incorporated the Object-oriented approaches used by ORTC – the alternative spec to WebRTC at the time. Today, mediasoup is a popular SFU choice among skilled WebRTC developers. mediasoup’s low-level native means this skill is required.

• Digium What are Managed IT Services?

  A managed IT service is an information technology (IT) task provided by a third-party service provider and delivered to a business customer.

  “Managed services” refers to outsourcing information technology (IT) processes and functions to improve operations and reduce expenses. It’s a way to augment your company IT staff with access to specialized expertise and not worry about the cost and complexities of hiring and staffing for 24/7/365 critical business functions.
  Managed services are ideal for companies that:

  • Rely on IT infrastructure to support their daily business operations
  • Have training or specialty gaps in their IT staff or have teams that have become bogged down in routine maintenance and cannot focus on value-generating objectives
  • Need IT budget predictability and scalability

  What are Managed IT Solutions?

   
  Businesses outsource a plethora of IT-related services to managed IT solutions providers, including:

  • Cloud Communications – This encompasses multiple communications technologies from business phone systems, VoIP calling, email, chat, video conferencing and collaboration, unified communications-as-a-service (UCaaS), virtual call centers, SIP trunking, and more.
  • Networking – A service provider typically develops, controls, and manages communication networks. Services typically offered include:
    • Internet access

  What is a Managed IT Service Provider?

   
  In a managed service arrangement, the managed service provider (MSP) is responsible for the functionality of IT services and equipment for the client, who typically pays on a monthly retainer basis.

  Companies that offer managed services are called managed service providers (MSPs). MSPs are third-party companies that remotely manage IT infrastructure and systems. Small and medium businesses (SMBs), nonprofits, government agencies, and enterprises across various industry verticals leverage MSPs to deploy and manage technology solutions.

  Typically, an MSP delivers applications and management services through the Internet under a contractual service-level agreement (SLA). The SLA details qualitative and quantitative performance metrics that govern the MSP and customer engagement.

  Key Benefits of Managed IT Service Providers for Businesses

  • Reduced technology costs
  • Domain expertise
  • Specialized talent
  • Scalability
  • Emerging tech know-how
  • Future-proof environments

  MSPs handle complex or repetitive tasks required to maintain a client’s IT infrastructure and typically are engaged in managing the following activities:

  • Sourcing and managing IT infrastructure
  • Delivering managed communications and collaboration services
  • Offering technical and software training and support
  • Sourcing and managing security solutions
  • Managing client user accounts in applications and portals
  • Handling contract management for underlying technology vendors
  • Assisting with compliance and risk management
  • Managing third-party contractors
  • More

  Why Outsource to a Managed IT Service Provider?

   
  Businesses of all sizes typically offload the management of select IT services for these key reasons:

  • Issue-Resolution Ownership – MSPs working with you in an ongoing capacity are incented to focus on preventing problems and quickly address issues to continue to win your business each month.
  • Solution Stability – MSPs provide 24/7/365 monitoring and proactive maintenance, which means they can respond to issues quickly and head off system failure and downtime in advance.
  • Predictable Costs – Expenses fit neatly into monthly payments, eliminating the need for significant capital outlays to deploy services. Likewise, you never get an unforeseen bill for something that breaks.
  • Infrastructure Modernization – MSPs go beyond just fixing your existing systems. They provide recommendations and create migration plans for upgrades to new and modernized versions of your underlying network infrastructure components while keeping them up to date and in alignment with your technical and business objectives.

• Jitsi Low-latency conference streaming to very large audiences

  Jitsi today supports life-streaming conferences to large audiences through our Jibri tool – this tool renders all the media from the conference, and forwards it to a streaming service such as YouTube.

  This approach works, but it has limitations.  In addition to being computationally expensive, it also introduces substantial latency to the media.  This can be a problem when interaction is needed between the participants in the conference and the audience, for example for a text-based question-and-answer session.

  This article will describe a new approach to live-streaming media, which uses Jitsi’s builtin functionality, without transcoding, to reach potentially very large audiences with latency comparable to that of a live conference.

  Overview

  The basic approach to media distribution for this solution is straightforward – simply forward media to all the audience members in the same way that they are forwarded today to conference participants – i.e. as individual RTP streams over WebRTC.  This can re-use Jitsi’s existing well-tested technology to distribute the media and have it arrive at receivers and be played out to viewers.

  The challenge, of course, is to scale Jitsi’s back-end services so they can support sending media to very large numbers of viewers, potentially in the hundreds of thousands or more.  The rest of this article will discuss some of the architectural enhancements we need to make to Jitsi to support this.

  The first insight that will make this possible is to realize that in a streaming scenario, while the conference’s active participants need to know that they are being watched by an audience, they don’t need to know all the audience members’ identities or presence in real-time; nor do the audience members need to know about each other.  Thus, the system can be modified such that presence information about individual audience members is not sent to other conference participants, or to unnecessary parts of the backend; this reduces the amount of signaling traffic substantially.

  The second substantial change that we are making to the backend is to be able to have more sophisticated topologies for the Jitsi Videobridges to relay media among them.  Currently, when more than one Jitsi Videobridge is used in a conference (in Jitsi’s Octo/Relay technology), the bridges are connected to each other in a full mesh.  This topology minimizes the latency for media, but would not scale to very large conferences, where e.g. hundreds of thousands of participants might need several hundred bridges.  If every bridge in such a conference were connected to every other one, the bridges could be overloaded just sending media out.

  Instead, we are developing technology that can arrange bridges into more elaborate topologies.  In particular, our plan for very large conferences is to still have the conference’s active participants be connected to bridges which are arranged in a mesh; but the audience members would then be connected to bridges whose interconnection forms a tree extending from various nodes of the core mesh, so that the core media servers would only need to send media out to a limited number of connections to the audience’s bridges, which would then be forwarded out to the audience, possibly relaying through multiple bridges on the way.

  

  Finally, changes need to be made for the signaling servers used by the Jitsi back-end.  While information about audience members only needs to be propagated to selected back-end infrastructure servers, information about a conference’s active participants needs to be forwarded to the entire audience.  The existing XMPP servers that the Jitsi back-end uses aren’t designed for this level of load.  Thus, we are developing solutions such that this participant information can be mirrored from one XMPP server to another, allowing each server to handle only a manageable number of client connections while still getting the information to the entire audience quickly.

  Stay tuned!

  Your personal meetings team.

• Digium UCaaS as PBX Replacement: Part 2

  In my last blog, I wrote about a customer just wanting basic PBX features from “25 years ago” and whether it was possible to buy a business phone system today that would be able to effectively replace one of these older systems.

  The answer is “of course you can get a phone system” that handles the PBX feature requirements from 25 years ago. And it will do exactly what you want it to do, and are used to doing, in terms of calling and call routing and audio conferencing and voice mail, etc. And it can still be on-premises if you wish, but it can also run in the cloud. And you can use a handset just like your current system has. If this is what you want, we have it.

  But it will also come with other features, or the ability to add these features, because that is what many customers want today:

  • Chat
  • Presence
  • Video calling
  • Mobility (Calling to and from your smartphone and laptop)
  • Integrations to CRM systems
  • Ability to customize via adding applications (such as notification apps)

  So don’t be confused and don’t be afraid to upgrade because of the marketing buzzwords used today. You’ll have all your old features, but you’ll be able to use these new features as well. For instance, the mobility feature allows your business phone number to follow you around on your laptop and Smartphone – it will make you “look bigger” to your customers since you’ll be reachable more easily.

  Upgrade so you don’t put your business at risk because of a potentially failing old system. Come talk to us and we’ll be happy to help. PBXs are there today, just in different clothing.

• Digium UCaaS and the Education Industry: Equip Your School with Cutting-Edge Communications

  With Sangoma’s Education Solutions, School is Never Out for the Summer

  Education requires total commitment, and for good reason. After all, it involves nothing less than preparing young people for lifelong personal and professional success. Considering the stakes, school systems should prioritize high-quality and worry-free communications, but all too often they face challenges implementing and supporting the latest in telephony. Let’s explore why.

  Barriers to High-Quality School Communication

  School administrators are often confronted with funding shortfalls and end up scrapping IT investments. If that isn’t bad enough, many schools don’t have a permanent IT professional on staff, which means critical communications infrastructure goes unmaintained and improvements fall to the wayside.

  On top of this, user-friendliness inhibits the successful implementation of next-generation communications systems. Educators need systems they can easily pick up and run with, especially given the fact that “13.8 percent of U.S. teachers are either leaving their school or the profession altogether.” With this in mind, it’s clear that successful systems can’t require a steep learning curve. Educators need a solution that lets them focus on what matters most: teaching! 

  Thankfully, there is a solution that overcomes these not-so-insignificant barriers: Unified Communications as a Service (UCaaS). 

  What is UCaaS?

  Educators require an easy way to interact with parents, administrators, students, and coworkers. Many schools have answered that call by discarding existing telephony for cutting-edge voice over internet protocol (VoIP) solutions that pair high-quality voice with unified communication (UC) tools to create UCaaS systems. Uniting technologies like voice, video conferencing, instant messaging, email, SMS, and fax into a single platform, UCaaS is an affordable and customizable system that adapts to the needs of any school network. It can also have hugely positive implications for an organization’s overall effectiveness and culture, with recent survey data showing UCaaS translating to better productivity for 72% of respondents, higher collaboration for 91%, and faster problem solving for 88%.

  Ditch “Old-School” Methods

  “Parent notes” are a critical tool for keeping parents informed, but how often are they left in backpacks, found on the floor of the bus, or worse – eaten by the dog? With UCaaS in an educator’s corner, teachers can ditch these types of archaic communication methods in favor of crystal-clear voice or high-resolution video. Whether it be a one-on-one call with a co-worker or student, or a group video conference with parents, the flexibility maximizes the effectiveness of a school’s messaging by supporting whichever channel works best for the stakeholders involved. And this is just one example; the possibilities are practically endless when technology is on your side. 

  User-Friendly, Affordable Communications are as

  Easy as 1, 2, 3

  As a seasoned IT vendor successfully equipping schools with the best communication solutions for years, Sangoma has discovered an ideal way forward. By striking a much-needed balance through “must have” features while also remaining affordable, we ensure that schools will never be “out for the summer” or any other season when they work with us. 

  “It looks like we are saving about $400 a month so far,” said Sadie O’Brien, IT director for the Shiocton School District, after deciding to transition to [Sangoma] Switchvox.

  By eliminating up-front costs, Sangoma UC expertly walks the fine line between offering advanced communication features without straining an institution’s IT funding. Additional savings are gained from low annual fees, and the solution operates through an all-inclusive pricing model. This fixed, consistent, subscription-style billing structure fits comfortably within school system budgets. 

  What’s in it for You?

  Sangoma UC doesn’t just solve problems created by sparse technology budgets, it also addresses the administrative challenges faced by these institutions. The system can be administered via a single computer connected to the network – with no coding required. Everything is geared toward lowering the learning curve and easing the burden for education professionals right from the get-go. Let’s take a closer look at how it can impact some of the primary stakeholders within a given school district: 

  IT Professionals: IT support staff gain major advantages with Sangoma UC in that it requires no special software, hardware, or license keys – meaning there’s nothing to download or install. The entire system can be managed through a single pane of glass with customizable views and widgets. With a subscription-based model, dealing with lengthy updates or cumbersome maintenance becomes a thing of the past, instead transitioning to the vendor’s responsibility. 

  Teachers: The typical teacher is overworked and overwhelmed, meaning that any technology they use must always help, never hinder. Sangoma UC is simple and intuitive enough that teachers can simply pick it up and immediately start taking advantage of its mobility features, dedicated conference rooms, and more. 

  Administrators: Administrators within school districts have a lot on their plates – from tracking absences, to managing calls from parents and staff, to sending out alerts and emergency messages. Sangoma streamlines these workflows considerably with a full suite of easy-to-learn features, such as IVR, auto attendant, receptionist console, mobile and desktop apps, and RAY BAUM compliance.

  Move Education into the Future with Sangoma

  As a 100% web-based system, Sangoma UC centralizes communications and ensures access to all messages, applications, and tools, regardless of where users are or what device they’re using. 

  Having equipped more than 1,000 schools, we’re well aware of the communication challenges faced by school districts.

• Digium UCaaS as PBX Replacement: Part 1

  Yes, there are still business systems called “PBX’s” out there. These are on-premises business phone systems that basically just did calling in and out of a building, offered voice mail, could perform an audio conference call, could forward a call, and had a some ‘advanced” calling features like ring groups, or sending group messages (i.e. recording a message, and then sending it to a group of people – like an email but you recorded the email), or call screening. The phone system that ran the business if you will.

  And they ruled the roost at one time. You learned many of the intricacies of these systems to be the most effective communicator out there, augmenting your email with these phone systems features.

  These systems are out there still. Not all have been upgraded yet. But they are old, and many of these systems are even out of maintenanace. Still chugging along…until they are not….
  As VoIP marched on and the internet networks became faster, other communication modes such as chat and video entered the fray, and the need to have the systems on-premises dissipated. Today’s UCaaS systems were born.

  And with it it came newfangled terminology. No more analog and digital. Seats, bandwidth, Unified Communications, trunking, hosted, cloud, multi-tenant, single-tenant, collaboration, single sign-on, UCaaS, mobility, and CPaaS are now typical words used.

  But this doesn’t mean the requirements of the PBXs of 25 years ago are different. The need to have a phone system that “runs the business” is still there. And I’ve had some prospects / customers kind of wondering what is going on – “can’t we just get a phone system?”. And these prospects have not upgraded since it’s kind of confusing to them. They want to, because they know the “chugging along” at some point will simply stop, but they don’t want to make a mistake, or buy something they won’t be able to work well.

  The answer is “of course you can get a phone system”. I’ll talk about this more in my next blog.

• ng-voice Understanding 3GPP

  When it comes to developing new telecom technologies, there are hundreds of different factors to consider. Yet one crucial aspect of this process that cannot be overlooked is ensuring compliance with industry standards.

  About 3GPP

  The 3rd Generation Partnership Project (3GPP) is a collection of organizations that develop and recommend standards for the telecommunications industry. 

   

  The collective was initially formed in December 1998 when the European Telecommunications Standards Institute (ETSI) partnered with other standard development organizations to evolve the new technologies for the third generation (3G) of cellular networks. Since its formation, 3GPP has developed the most widely used 3G standard, as well as global fourth-generation (4G) and fifth-generation (5G) standards. 

   

  Technology engineers are advised to follow these principles when developing their products. The global technical specifications ensure compatibility between components because those standards are governing how those different systems and devices are built around the globe.

   

  The adoption of SIP by the 3rd Generation Partnership Project (3GPP) as a call control protocol was a major milestone for the standardization world as the IMS architecture became the first SIP-based standard commercial system, setting the guideline for following developments. Driven by the demand for multimedia communication services, the industry had to search for an efficient way to deploy those services in the existing and new networks. Wireless telecommunication operators and vendors had to adapt quickly, enabling a rapid introduction of IP and SIP services into their network through the IMS. The standardization effort has been driven by the 3GPP in close work with the Internet Engineering Task Force (IETF) to ensure the harmonization of standards.

   

  SIP standards set the baseline for the creation of CSCF and other functional elements in the IMS network, ensuring the interoperability of various network elements (UE, CSCF, etc), defining basic communication rules between the elements, and setting the guidelines for interconnecting with other network architectures. The standard body comprises the standards for data plane, user plane as well as session control in the SIP network.

  Why is it important for vendors to be standards-compliant

  There are a number of reasons why observing 3GPP principles is beneficial to vendors and operators alike, these include:
  

  Interoperability: 

   

  Operators will often look to integrate different technologies from multiple sources and vendors. Adhering to 3GPP’s standards allows vendors to incorporate best-in-class methodologies, processes, and engineering specifications, ensuring that the technologies required by operators all ‘speak the same language’ and can effectively integrate with one another. 

   

  Importantly, while 3GPP encourages companies to adhere to a specific standard, it does not stifle innovation or differentiation in the market as no limit is placed on how vendors develop and incorporate software together. 

  
  

  Scalability: 

   

  Talking of scalability, by meeting the standards set out by 3GPP, vendors, and operators can avoid a ‘rip and replace’ approach to existing infrastructure, making the deployment process faster and more cost-effective for all involved. Developing technologies in such a way that they’ll easily fit in with existing systems and can be easily adapted depending on growing subscriber bases, also allows for greater scalability as operator networks change and evolve. 

  
  

  Global reach: 

   

  The ability of customers and businesses to use their devices in multiple countries can also be attributed to the principles developed by 3GPP. Through these standards, network equipment can be manufactured and operated around the world, with no restrictions on usage – a huge development for the industry and a crucial factor for operators seeking scalability beyond their home borders.

  Going one step further

  The above factors are crucial to operators. However, the benefits of standardization go a step further and encourage greater collaboration across the industry. Technology developers are all working towards the common goal of furthering innovation in telecommunications, and by following the same standards and developing interoperable solutions, this can be done collectively, for the future of the industry. 

   

  ng-voice’s cloud-native IMS VoLTE / VoNR solution is standard-compliant, ensuring that it follows the principles laid out by 3GPP and can be integrated alongside other vendor technologies.

• Digium Let’s Revisit Hot Desking

  Back in June, I wrote a blog about hot desking. And I wrote at the time “But is hot desking of a physical phone an obsolete concept with Unified Communications? Does it even need to be in RFPs anymore? Because with UC, you can make and take phone calls with your work extension from your computer, or from your smartphone, via a UC client. I can do that no matter where I sit in the office.”

  Now, 4 months later, I got an email from a reader asking if I wanted to take that back because with the return to the office, many companies are going to hybrid models. Hybrid, to many, in addition to working both in the office and at home, means there are fewer offices. Because companies have downsized the physical space to save money.

  And now when you show up to the actual office, instead of going to a specific office or cubicle, you might just have to go find a place to sit. And so the phone at the “place to sit” is not hard wired with your extension. What I wrote is still valid and maybe even more-so if this is what hybrid means.

  What I will acknowledge, though, is that maybe there are some specific jobs where the company wants you on a deskphone, instead of on your smartphone, or the UC app. Security issues, for instance might come into play. So yes, I can see this being a part of RFPs with a hybrid environment if the use demands a physical phone while at the office.

  But if the UC client is used when working from home, what’s the difference if you are at home or in the office? Mobility is mobility. That’s all I’ll say.

• WebRTC Hacks Post-Peak WebRTC Developer Trends: An Open Source Analysis
  

  WebRTC had its peaks during the pandemic, but how is it doing now? Did all those new projects die, putting the community back at pre-pandemic “normal” levels or is WebRTC still going strong? I built and analyzed a dataset from over a million GitHub’s events since 2019 to help answer are there many new WebRTC-related repos, how many new users is WebRTC attracting, is the community coding as much as it used to, how are new API's like Insertable Streams and WebCodecs doing?

• ng-voice Sustainability in the telecommunications industry – challenges and opportunities

  Nowadays, it’s difficult to ignore the words sustainability, climate action, or carbon neutrality—and quite rightly so. 

   

  According to data from this 2021 BCG report, as an industry, telecoms generate 1.6% of all carbon emissions (almost 90% of which comes from Scope 3 emissions). Indeed, the overall ICT sector which comprises telecoms is responsible for 3-4% of all global emissions, and shockingly, equating to twice the levels of the aviation industry. If left unmanaged, the telecoms industry could be responsible for up to 14% of global CO2 emissions by 2040. This will only grow as data demands increase and consumers own more devices. This is forcing severe conversation about sustainability and net zero ambitions amongst service providers and vendors. 

   

  In an attempt to remedy the impact telecoms has on our planet, the industry — led by the GSMA — has set ambitions to transform itself to reach Net Zero carbon emissions by 2050. The GSMA is also encouraging the industry to think about how operators can support the United Nations’ Sustainable Development Goals (SDGs), by embedding these into their overall corporate social responsibility (CSR) strategy and prioritizing relevant goals that will see them have the greatest impact. In fact, some major operators are now leading the change by adopting SDGs as a key part of building a greener future and helping society thrive.

   

  So as mobile data continues to grow, legacy networks are being shut down and more 5G networks are deployed, how can the industry curb its impact on carbon emission and on our planet? One option is to look at more resource-efficient software solutions, such as cloud-native software. 

  How does sustainability relate to cloud-native solutions?

  A report by Accenture suggests that migrating to the cloud would lower the IT Industry’s Carbon Emissions to an equivalent of taking 22 million cars off the road, apart from resulting in 30-40% total cost of ownership (TCO) savings.

   

  As the first fully containerized and cloud-native IMS in the market, our solution’s resource footprint is dramatically lower than that of traditional legacy solutions — which not only presents a huge OPEX saving for our customers but also proves to be a more sustainable and energy-efficient option.

• François Marier Upgrading from chan_sip to res_pjsip in Asterisk 18

  After upgrading to Ubuntu Jammy and Asterisk 18.10, I saw the following messages in my logs:

  WARNING[360166]: loader.c:2487 in load_modules: Module 'chan_sip' has been loaded but was deprecated in Asterisk version 17 and will be removed in Asterisk version 21.
  WARNING[360174]: chan_sip.c:35468 in deprecation_notice: chan_sip has no official maintainer and is deprecated.  Migration to
  WARNING[360174]: chan_sip.c:35469 in deprecation_notice: chan_pjsip is recommended.  See guides at the Asterisk Wiki:
  WARNING[360174]: chan_sip.c:35470 in deprecation_notice: https://wiki.asterisk.org/wiki/display/AST/Migrating+from+chan_sip+to+res_pjsip
  WARNING[360174]: chan_sip.c:35471 in deprecation_notice: https://wiki.asterisk.org/wiki/display/AST/Configuring+res_pjsip
  

  and so I decided it was time to stop postponing the overdue migration of my working setup from chan_sip to res_pjsip.

  It turns out that it was not as painful as I expected, though the conversion script bundled with Asterisk didn't work for me out of the box.

  Debugging

  Before you start, one very important thing to note is that the SIP debug information you used to see when running this in the asterisk console (asterisk -r):

  sip set debug on
  

  now lives behind this command:

  pjsip set logger on
  

  SIP phones

  The first thing I migrated was the config for my two SIP phones (Snom 300 and Snom D715).

  The original config for them in sip.conf was:

  [2000]
  ; Snom 300
  type=friend
  qualify=yes
  secret=password123
  encryption=no
  context=full
  host=dynamic
  nat=no
  directmedia=no
  mailbox=10@internal
  vmexten=707
  dtmfmode=rfc2833
  call-limit=2
  disallow=all
  allow=g722
  allow=ulaw
  
  [2001]
  ; Snom D715
  type=friend
  qualify=yes
  secret=password456
  encryption=no
  context=full
  host=dynamic
  nat=no
  directmedia=yes
  mailbox=10@internal
  vmexten=707
  dtmfmode=rfc2833
  call-limit=2
  disallow=all
  allow=g722
  allow=ulaw
  

  and that became the following in pjsip.conf:

  [transport-udp]
  type = transport
  protocol = udp
  bind = 0.0.0.0
  external_media_address = myasterisk.dyn.example.com
  external_signaling_address = myasterisk.dyn.example.com
  local_net = 192.168.0.0/255.255.0.0
  
  [2000]
  type = aor
  max_contacts = 1
  
  [2000]
  type = auth
  username = 2000
  password = password123
  
  [2000]
  type = endpoint
  context = full
  dtmf_mode = rfc4733
  disallow = all
  allow = g722
  allow = ulaw
  direct_media = no
  mailboxes = 10@internal
  auth = 2000
  outbound_auth = 2000
  aors = 2000
  
  [2001]
  type = aor
  max_contacts = 1
  
  [2001]
  type = auth
  username = 2001
  password = password456
  
  [2001]
  type = endpoint
  context = full
  dtmf_mode = rfc4733
  disallow = all
  allow = g722
  allow = ulaw
  direct_media = yes
  mailboxes = 10@internal
  auth = 2001
  outbound_auth = 2001
  aors = 2001
  

  The different direct_media line between the two phones has to do with how they each connect to my Asterisk server and whether or not they have access to the Internet.

  Internal calls

  For some reason, my internal calls (from one SIP phone to the other) didn't work when using "aliases". I fixed it by changing this blurb in extensions.conf from:

  [speeddial]
  exten => 1000,1,Dial(SIP/2000,20)
  exten => 1001,1,Dial(SIP/2001,20)
  

  to:

  [speeddial]
  exten => 1000,1,Dial(${PJSIP_DIAL_CONTACTS(2000)},20)
  exten => 1001,1,Dial(${PJSIP_DIAL_CONTACTS(2001)},20)
  

  I have not yet dug into what this changes or why it's necessary and so feel free to leave a comment if you know more here.

  PSTN trunk

  Once I had the internal phones working, I moved to making and receiving phone calls over the PSTN, for which I use VoIP.ms with encryption.

  I had to change the following in my sip.conf:

  [general]
  register => tls://555123_myasterisk:password789@vancouver2.voip.ms
  externhost=myasterisk.dyn.example.com
  localnet=192.168.0.0/255.255.0.0
  tcpenable=yes
  tlsenable=yes
  tlscertfile=/etc/asterisk/asterisk.cert
  tlsprivatekey=/etc/asterisk/asterisk.key
  tlscapath=/etc/ssl/certs/
  
  [voipms]
  type=peer
  host=vancouver2.voip.ms
  secret=password789
  defaultuser=555123_myasterisk
  context=from-voipms
  disallow=all
  allow=ulaw
  allow=g729
  insecure=port,invite
  canreinvite=no
  trustrpid=yes
  sendrpid=yes
  transport=tls
  encryption=yes
  

  to the following in pjsip.conf:

  [transport-tls]
  type = transport
  protocol = tls
  bind = 0.0.0.0
  external_media_address = myasterisk.dyn.example.com
  external_signaling_address = myasterisk.dyn.example.com
  local_net = 192.168.0.0/255.255.0.0
  cert_file = /etc/asterisk/asterisk.cert
  priv_key_file = /etc/asterisk/asterisk.key
  ca_list_path = /etc/ssl/certs/
  method = tlsv1_2
  
  [voipms]
  type = registration
  transport = transport-tls
  outbound_auth = voipms
  client_uri = sip:555123_myasterisk@vancouver2.voip.ms
  server_uri = sip:vancouver2.voip.ms
  
  [voipms]
  type = auth
  password = password789
  username = 555123_myasterisk
  
  [voipms]
  type = aor
  contact = sip:555123_myasterisk@vancouver2.voip.ms
  
  [voipms]
  type = identify
  endpoint = voipms
  match = vancouver2.voip.ms
  
  [voipms]
  type = endpoint
  context = from-voipms
  disallow = all
  allow = ulaw
  allow = g729
  from_user = 555123_myasterisk
  trust_id_inbound = yes
  media_encryption = sdes
  auth = voipms
  outbound_auth = voipms
  aors = voipms
  rtp_symmetric = yes
  rewrite_contact = yes
  send_rpid = yes
  timers = no
  

  The TLS method line is needed since the default in Debian OpenSSL is too strict. The timers line is to prevent outbound calls from getting dropped after 15 minutes.

  Finally, I changed the Dial() lines in these extensions.conf blurbs from:

  [from-voipms]
  exten => 5551231000,1,Goto(2000,1)
  exten => 2000,1,Dial(SIP/2000&SIP/2001,20)
  exten => 2000,n,Goto(in2000-${DIALSTATUS},1)
  exten => 2000,n,Hangup
  exten => in2000-BUSY,1,VoiceMail(10@internal,su)

• François Marier Setting up a JMP SIP account on Asterisk

  JMP offers VoIP calling via XMPP, but it's also possibly to use the VoIP using SIP.

  The underlying VoIP calling functionality in JMP is provided by Bandwidth, but their old Asterisk instructions didn't quite work for me. Here's how I set it up in my Asterisk server.

  Get your SIP credentials

  After signing up for JMP and setting it up in your favourite XMPP client, send the following message to the cheogram.com gateway contact:

  reset sip account
  

  In response, you will receive a message containing:

  • a numerical username
  • a password (e.g. three lowercase words separated by spaces)

  Add SIP account to your Asterisk config

  First of all, I added the following to my /etc/asterisk/pjsip.conf:

  [transport-udp]
  type = transport
  protocol = udp
  bind = 0.0.0.0
  external_media_address = myasterisk.dyn.example.com
  external_signaling_address = myasterisk.dyn.example.com
  local_net = 192.168.0.0/255.255.0.0
  
  [jmp]
  type = registration
  contact_user = 5554561000
  transport = transport-udp
  outbound_auth = jmp
  client_uri = sip:5554561000@jmp.cbcbc7.auth.bandwidth.com:5008
  server_uri = sip:jmp.cbcbc7.auth.bandwidth.com:5008
  
  [jmp]
  type = auth
  password = three secret words
  username = 5554561000
  
  [jmp]
  type = aor
  contact = sip:5554561000@jmp.cbcbc7.auth.bandwidth.com:5008
  
  [jmp]
  type = identify
  endpoint = jmp
  match = jmp.cbcbc7.auth.bandwidth.com
  
  [jmp]
  type = endpoint
  context = from-jmp
  dtmf_mode = rfc4733
  disallow = all
  allow = ulaw
  allow = g729
  auth = jmp
  outbound_auth = jmp
  aors = jmp
  rtp_symmetric = yes
  rewrite_contact = yes
  send_rpid = yes
  timers = no
  

  and for reference, here's the blurb for my Snom 300 SIP phone:

  [2000]
  type = aor
  max_contacts = 1
  
  [2000]
  type = auth
  username = 2000
  password = password123
  
  [2000]
  type = endpoint
  context = full
  dtmf_mode = rfc4733
  disallow = all
  allow = g722
  allow = ulaw
  mailboxes = 10@internal
  auth = 2000
  outbound_auth = 2000
  aors = 2000
  

  I checked that the registration was successful by running asterisk -r and then typing:

  pjsip set logger on
  

  before reloading the configuration using:

  reload
  

  Create Asterisk extensions to send and receive calls

  Once I got registration to work, I hooked this up with my other extensions so that I could send and receive calls using my JMP number.

  In /etc/asterisk/extensions.conf, I added the following:

  [from-jmp]
  include => home
  exten => s,1,Goto(2000,1)
  

  where home is the context which includes my local SIP devices and 2000 is the extension I want to ring.

  Then I added the following to enable calls to any destination within the North American Numbering Plan:

  [pstn-jmp]
  exten => _1NXXNXXXXXX,1,Set(CALLERID(all)=Francois Marier <username>)
  exten => _1NXXNXXXXXX,n,Dial(PJSIP/${EXTEN}@jmp)
  exten => _1NXXNXXXXXX,n,Hangup()
  exten => _NXXNXXXXXX,1,Set(CALLERID(all)=Francois Marier <username>)
  exten => _NXXNXXXXXX,n,Dial(PJSIP/1${EXTEN}@jmp)
  exten => _NXXNXXXXXX,n,Hangup()
  

  Here username is my bwsip numerical username. When calls are placed, this gets automatically swapped in by my real JMP phone number, but Bandwidth appears to require its users to use their username in there caller ID string.

  For reference, here's the rest of my dialplan in /etc/asterisk/extensions.conf:

  [general]
  static=yes
  writeprotect=no
  clearglobalvars=no
  
  [public]
  exten => _X.,1,Hangup(3)
  
  [sipdefault]
  exten => _X.,1,Hangup(3)
  
  [default]
  exten => _X.,1,Hangup(3)
  
  [internal]
  include => home
  
  [full]
  include => internal
  include => pstn-jmp
  exten => 707,1,VoiceMailMain(10@internal)
  
  [home]
  exten => 2000,1,Dial(PJSIP/2000,20)
  exten => 2000,n,Goto(in2000-${DIALSTATUS},1)
  exten => 2000,n,Hangup
  exten => in2000-BUSY,1,VoiceMail(10@internal,su)
  exten => in2000-BUSY,n,Hangup
  exten => in2000-CONGESTION,1,VoiceMail(10@internal,su)

  exten => in2000-NOANSWER,1,VoiceMail(10@internal,su)
  exten => in2000-NOANSWER,n,Hangup
  exten => _in2000-.,1,Hangup(16)
  

  Firewall

  Finally, I opened a few ports in my firewall by putting the following in /etc/network/iptables.up.rules:

  # SIP and RTP on UDP (jmp.cbcbc7.auth.bandwidth.com)
  -A INPUT -s 67.231.2.13/32 -p udp --dport 5008 -j ACCEPT

• Digium Sangoma Announces Shipment of Its One Millionth Desk Phone

  

  Wow, we just shipped our one millionth phone! Over 10 years ago, Sangoma (and Digium) decided that having a seamless end-to-end Unified Communication system was important. And at that time, end to end system meant just the phone and the UC systems. So, we decided to release our own phones.

  These days, a UC system includes Sangoma’s UCaaS service (or on-premises version), the desk phone, mobile and desktop client software, Sangoma’s collaboration-as-a-service client (TeamHub), and Sangoma’s video meetings service (Sangoma Meet).

  The UC industry has come quite a long way in 10 years, but the phone is still part of the system, especially for brick-and-mortar businesses. And we are proud to serve all of these customers.

  As I said in the press release about this news, “Many of our customers use both desk phones as well as our mobile and desktop clients to communicate. And since we manufacture our own desk phones and develop our own cloud communications software, we are able to provide deep integration between our phones and our cloud communications services, in a way that other phone manufacturers or UCaaS companies simply cannot do. This kind of integration has contributed to the successful growth of this important product line at Sangoma, differentiating us from our competitors and leading to this one-million-unit milestone.“

  So, thank you to all the users of these phones, the distributors who fulfilled these phones, and the resellers who put our solutions into the end-user businesses. Let’s count the next million.

  The post Sangoma Announces Shipment of Its One Millionth Desk Phone appeared first on Sangoma Technologies.

• François Marier Using a Let's Encrypt TLS certificate with Asterisk 16.2

  In order to fix the following error after setting up SIP TLS in Asterisk 16.2:

  asterisk[8691]: ERROR[8691]: tcptls.c:966 in __ssl_setup: TLS/SSL error loading cert file. <asterisk.pem>
  

  I created a Let's Encrypt certificate using certbot:

  apt install certbot
  certbot certonly --standalone -d hostname.example.com
  

  To enable the asterisk user to load the certificate successfuly (it doesn't have permission to access the certificates under /etc/letsencrypt/), I copied it to the right directory:

  cp /etc/letsencrypt/live/hostname.example.com/privkey.pem /etc/asterisk/asterisk.key
  cp /etc/letsencrypt/live/hostname.example.com/fullchain.pem /etc/asterisk/asterisk.cert
  chown asterisk:asterisk /etc/asterisk/asterisk.cert /etc/asterisk/asterisk.key
  chmod go-rwx /etc/asterisk/asterisk.cert /etc/asterisk/asterisk.key
  

  Then I set the following variables in /etc/asterisk/sip.conf:

  tlscertfile=/etc/asterisk/asterisk.cert
  tlsprivatekey=/etc/asterisk/asterisk.key
  

  Automatic renewal

  The machine on which I run asterisk has a tricky Apache setup:

  • a webserver is running on port 80
  • port 80 is restricted to the local network

  This meant that the certbot domain ownership checks would get blocked by the firewall, and I couldn't open that port without exposing the private webserver to the Internet.

  So I ended up disabling the built-in certbot renewal mechanism:

  systemctl disable certbot.timer certbot.service
  systemctl stop certbot.timer certbot.service
  

  and then writing my own script in /etc/cron.daily/certbot-francois:

  #!/bin/bash
  TEMPFILE=`mktemp`
  
  # Stop Apache and backup firewall.
  /bin/systemctl stop apache2.service
  /usr/sbin/iptables-save > $TEMPFILE
  
  # Open up port 80 to the whole world.
  /usr/sbin/iptables -D INPUT -j LOGDROP
  /usr/sbin/iptables -A INPUT -p tcp --dport 80 -j ACCEPT
  /usr/sbin/iptables -A INPUT -j LOGDROP
  
  # Renew all certs.
  /usr/bin/certbot renew --quiet
  
  # Restore firewall and restart Apache.
  /usr/sbin/iptables -D INPUT -p tcp --dport 80 -j ACCEPT
  /usr/sbin/iptables-restore < $TEMPFILE
  /bin/systemctl start apache2.service
  
  # Copy certificate into asterisk.
  cp /etc/letsencrypt/live/hostname.example.com/privkey.pem /etc/asterisk/asterisk.key
  cp /etc/letsencrypt/live/hostname.example.com/fullchain.pem /etc/asterisk/asterisk.cert
  chown asterisk:asterisk /etc/asterisk/asterisk.cert /etc/asterisk/asterisk.key
  chmod go-rwx /etc/asterisk/asterisk.cert /etc/asterisk/asterisk.key
  
  # Commit changes to etckeeper and restart asterisk.
  pushd /etc/ > /dev/null
  /usr/bin/git add letsencrypt asterisk
  DIFFSTAT="$(/usr/bin/git diff --cached --stat)"
  if [ -n "$DIFFSTAT" ] ; then
      /usr/bin/git commit --quiet -m "Renewed letsencrypt certs." letsencrypt asterisk
      echo "$DIFFSTAT"
      /bin/systemctl restart asterisk.service
  fi
  popd > /dev/null

• François Marier Encrypted connection between SIP phones using Asterisk

  Here is the setup I put together to have two SIP phones connect together over an encrypted channel. Since the two phones do not support encryption, I used Asterisk to provide the encrypted channel over the Internet.

  Installing Asterisk

  First of all, each VoIP phone is in a different physical location and so I installed an Asterisk server in each house.

  One of the server is a Debian stretch machine and the other runs Ubuntu bionic 18.04. Regardless, I used a fairly standard configuration and simply installed the asterisk package on both machines:

  apt install asterisk
  

  SIP phones

  The two phones, both Snom 300, connect to their local asterisk server on its local IP address and use the same details as I have put in /etc/asterisk/sip.conf:

  [1000]
  type=friend
  qualify=yes
  secret=password1
  encryption=no
  context=internal
  host=dynamic
  nat=no
  canreinvite=yes
  mailbox=1000@internal
  vmexten=707
  dtmfmode=rfc2833
  call-limit=2
  disallow=all
  allow=g722
  allow=ulaw
  

  Dialplan and voicemail

  The extension number above (1000) maps to the following configuration blurb in /etc/asterisk/extensions.conf:

  [home]
  exten => 1000,1,Dial(SIP/1000,20)
  exten => 1000,n,Goto(in1000-${DIALSTATUS},1)
  exten => 1000,n,Hangup
  exten => in1000-BUSY,1,VoiceMail(1000@mailboxes,su)
  exten => in1000-BUSY,n,Hangup
  exten => in1000-CONGESTION,1,VoiceMail(1000@mailboxes,su)
  exten => in1000-CONGESTION,n,Hangup
  exten => in1000-CHANUNAVAIL,1,VoiceMail(1000@mailboxes,su)
  exten => in1000-CHANUNAVAIL,n,Hangup
  exten => in1000-NOANSWER,1,VoiceMail(1000@mailboxes,su)
  exten => in1000-NOANSWER,n,Hangup
  exten => _in1000-.,1,Hangup(16)
  

  the internal context maps to the following blurb in /etc/asterisk/extensions.conf:

  [internal]
  include => home
  include => iax2users
  exten => 707,1,VoiceMailMain(1000@mailboxes)
  

  and 1000@mailboxes maps to the following entry in /etc/asterisk/voicemail.conf:

  [mailboxes]
  1000 => 1234,home,person@email.com
  

  (with 1234 being the voicemail PIN).

  Encrypted IAX links

  In order to create a virtual link between the two servers using the IAX protocol, I created user credentials on each server in /etc/asterisk/iax.conf:

  [iaxuser]
  type=user
  auth=md5
  secret=password2
  context=iax2users
  allow=g722
  allow=speex
  encryption=aes128
  trunk=no
  

  then I created an entry for the other server in the same file:

  [server2]
  type=peer
  host=server2.dyn.fmarier.org
  auth=md5
  secret=password2
  username=iaxuser
  allow=g722
  allow=speex
  encryption=yes
  forceencrypt=yes
  trunk=no
  qualify=yes
  

  The second machine contains the same configuration with the exception of the server name (server1 instead of server2) and hostname (server1.dyn.fmarier.org instead of server2.dyn.fmarier.org).

  Speed dial for the other phone

  Finally, to allow each phone to ring one another by dialing 2000, I put the following in /etc/asterisk/extensions.conf:

  [iax2users]
  include => home
  exten => 2000,1,Set(CALLERID(all)=Francois Marier <2000>)
  exten => 2000,2,Dial(IAX2/server1/1000)
  

  and of course a similar blurb on the other machine:

  [iax2users]
  include => home
  exten => 2000,1,Set(CALLERID(all)=Other Person <2000>)
  exten => 2000,2,Dial(IAX2/server2/1000)
  

  Firewall rules

  Since we are using the IAX protocol instead of SIP, there is only one port to open in /etc/network/iptables.up.rules for the remote server:

  # IAX2 protocol
  -A INPUT -s x.x.x.x/y -p udp --dport 4569 -j ACCEPT
  

  where x.x.x.x/y is the IP range allocated to the ISP that the other machine is behind.

  If you want to restrict traffic on the local network as well, then these ports need to be open for the SIP phone to be able to connect to its local server:

  # VoIP phones (internal)
  -A INPUT -s 192.168.1.3/32 -p udp --dport 5060 -j ACCEPT
  -A INPUT -s 192.168.1.3/32 -p udp --dport 10000:20000 -j ACCEPT
  

  where 192.168.1.3 is the static IP address allocated to the SIP phone.

• François Marier Connecting a VoIP phone directly to an Asterisk server

  On my Asterisk server, I happen to have two on-board ethernet boards. Since I only used one of these, I decided to move my VoIP phone from the local network switch to being connected directly to the Asterisk server.

  The main advantage is that this phone, running proprietary software of unknown quality, is no longer available on my general home network. Most importantly though, it no longer has access to the Internet, without my having to firewall it manually.

  Here's how I configured everything.

  Private network configuration

  On the server, I started by giving the second network interface a static IP address in /etc/network/interfaces:

  auto eth1
  iface eth1 inet static
      address 192.168.2.2
      netmask 255.255.255.0
  

  On the VoIP phone itself, I set the static IP address to 192.168.2.3 and the DNS server to 192.168.2.2. I then updated the SIP registrar IP address to 192.168.2.2.

  The DNS server actually refers to an unbound daemon running on the Asterisk server. The only configuration change I had to make was to listen on the second interface and allow the VoIP phone in:

  server:
      interface: 127.0.0.1
      interface: 192.168.2.2
      access-control: 0.0.0.0/0 refuse
      access-control: 127.0.0.1/32 allow
      access-control: 192.168.2.3/32 allow
  

  Finally, I opened the right ports on the server's firewall in /etc/network/iptables.up.rules:

  -A INPUT -s 192.168.2.3/32 -p udp --dport 5060 -j ACCEPT
  -A INPUT -s 192.168.2.3/32 -p tcp --dport 5060 -j ACCEPT
  -A INPUT -s 192.168.2.3/32 -p udp --dport 10000:20000 -j ACCEPT
  

  Network time synchronization

  In order for the phone to update its clock automatically using NTP, I installed chrony on the Asterisk server:

  apt install chrony
  

  then I configured it to listen on the private network interface and allow access from the VoIP phone by adding the following to /etc/chrony/conf.d/asterisk-local.conf:

  bindaddress 192.168.2.2
  allow 192.168.2.3
  

  Finally, I opened the right firewall port by adding a new rule to /etc/network/iptables.up.rules:

  -A INPUT -s 192.168.2.3 -p udp --dport 123 -j ACCEPT
  

  Accessing the admin page

  Now that the VoIP phone is no longer available on the local network, it's not possible to access its admin page. That's a good thing from a security point of view, but it's somewhat inconvenient.

  Therefore I put the following in my ~/.ssh/config to make the admin page available on http://localhost:8081 after I connect to the Asterisk server via ssh:

  Host asterisk
      LocalForward localhost:8081 192.168.2.3:80
  

  Allowing calls between local SIP devices

  Because this local device is not connected to the local network (192.168.1.0/24), it's unable to negotiate a direct media connection to any other local (i.e. one connected to the same Asterisk server) SIP device. What this means is that while calls might get connected successfully, by default, there will not be any audio in a call.

  In order for the two local SIP devices to be able to hear one another, we must enforce that all media be routed via Asterisk instead of going directly from one device to the other. This can be done using the directmedia directive (formerly canreinvite) in sip.conf:

  [1234]
  directmedia=no
  

  where 1234 is the extension of the phone.

• ng-voice The potential of 5G SA – how is it set to impact the industry?

  The arrival of 5G has been an exciting development in the telecoms space, with operators across the globe already rolling out the technology to enhance their services and offerings. But now even greater excitement is building as operators set their sights on true 5G – 5G Standalone (or 5G SA). So, what exactly is 5G SA and what opportunities does it unlock?

   

  5G SA uses the 5G NR (5G New Radio) access network on a 5G network core, unlike non-standalone 5G, which uses a 5G NR access network overlaid on an existing 4G LTE network core. 

   

  The widespread use of 5G SA has myriad benefits, including:

  • The complete reliance on a 5G core unlocks the benefits of true 5G, namely improved bandwidth and speed of connection for end-users
  • Increased ability to scale and enhanced spectral efficiencies
  • Ultra-low latency, contributing to an overall more seamless experience for end-users

  Critically, 5G SA will act as a key driver in the monetization of 5G, allowing telcos to recoup their investment into the new network by enabling new use cases for the entire sector, including:

  • Private networks – private, 5G SA networks benefit from resilience, security, and autonomy. 
  • IoT – 5G SA is ideal for meeting Critical IoT requirements, providing flexible edge computing, reliability, and supporting Network Data Analytics.
  • Network slicing – enabling new revenue opportunities through vertical applications such as smart manufacturing.

  With the Ericsson Mobility report highlighting that the 5G SA rollout will double by the end of 2022 and that within 5 years, 5G SA-compatible devices will account for nearly half of all mobile subscriptions, it’s crucial that we understand what its impact is going to be on the industry. 

   

  The current global rollout 

  Across the globe, we’re beginning to see operators rolling out 5G SA to deliver a fully 5G experience to end users. In 2021, Vodafone Germany launched a 5G SA network, with 1000 antennas in 170 cities and municipalities, and plans to deploy a fully-SA network by 2023. Late last year, Telia launched its 5G SA core in Finland, with the service being initially available to selected users in around 20 areas across Finland. 

   

  Many other EMEA operators have plans to launch 5G SA networks this year, including Telenor Denmark, Orange, Vodafone Spain and Vodafone UK, with the latter launching a commercial pilot trial of 5G SA last year. 

   

  However, despite this development and proliferation of 5G SA, there is still a vast number of operators who are without plans to roll out the technology and are lagging behind. This could be for a variety of reasons, however, the fundamental challenge operators face is integration.

   

  Integration of 5G SA is challenging, and it requires new infrastructure and architecture, rethinking operations, embracing cloud-nativity principles, and a software-centric approach. This entirely new way of thinking and operating could be holding telcos back from investing in 5G SA, however, the benefits it will bring and the use cases it unlocks are set to outweigh the challenges of implementation.  

   

  To unlock the true benefits of 5G SA, being cloud-native is key. Moving to a fully cloud-native infrastructure can add additional benefits to the already enhanced service, including flexibility and fast deployment, with lower costs.

   

  5G SA and VoNR

  When talking about the rollout of 5G SA, we cannot do so without thinking about voice services. The rollout of 5G SA will give rise to VoNR, seeing less reliance on VoLTE as more and more devices become 5G SA-compatible. 

   

  VoNR has many benefits for end-users, including enhanced voice quality and preventing fallback onto 4G networks, which improves the overall quality of call experience. 

  VoNR will form a key part of operators’ 5G SA journey, but it’s crucial that operators consider the quality and capabilities of their current IMS core solutions, to provide a service that fulfills customer needs and expectations. 

   

  At ng-voice, we offer a VoLTE/ VoNR solution that is truly cloud-native and fully containerized. Our cloud-native IMS is the first 100% containerized and Kubernetes-based fully-fledged IMS solution in the market. With the smallest container sizes, a high level of automation, and minimal use of resources, our IMS is scalable, flexible, cost-efficient, and easy to deploy and manage.

• Digium Sangoma’s New Logo

  Sangoma is constantly evolving. And with it, our logo is evolving along with us.

  

  When we purchased Digium in 2018, we made a change to our logo and at that time, incorporated part of the Digium logo. But since that time, we’ve purchased VoIP Innovations, Star2Star, and now NetFortris. We are a different company since 2018, and we figured it was time for our logo come along. While our logo has changed, we still have the same pride and commitment to Asterisk (and FreePBX). Nothing has changed in that regard.

  What has changed is we’ve now grown into being a world-class Communications as a Service provider with over 70% recurring revenue. And through our partners we serve businesses ranging from SMBs to multi-location regional and national retail chains. It’s been truly awesome to have been part of this growth.

  And while we are probably most associated today with UCaaS and it’s nice to get accolades from Gartner and Frost and Sullivan about UCaaS, we also offer cloud services that complement UCaaS – Contact Center, Video Meetings, Collaboration, MSP services, CPaaS / Applications, Desktop as a Service, Access Control and Fax for example. We offer a wide range of Communications-as-a-Services, one we think is the broadest in the industry.

  And so we wanted to incorporate some kind of cloud element into our logo – to always have that in the background when people come to our website, when we’re presenting, etc. Because that’s who we are and who we will continue to be. We are also a strong company in many ways – fiscally, determined, intrepid – and that steel blue color is meant to evoke that.

  Welcome to the new logo.

• Digium UCaaS & the Concept of “One-stop-shopping” for Other Required Communications Services

  Over the summer, I’ve written a few blogs about the Frost and Sullivan whitepaper called “Modern Cloud Communications Empower the Hybrid Workforce�. This will be my final blog about it. One other part of that whitepaper talked about Unified Communications and then about other communication services beyond just UC.

  Organizations adopting unified communications-as-a-service (UCaaS) show strong preference for one-stop shopping. They choose to purchase an array of correlated services from their cloud private branch exchange (PBX) provider:

  • 91% integrated meetings and messaging
  • 88% cybersecurity solutions
  • 88% device as a service
  • 85% SIP trunking
  • 84% MPLS
  • 82% SD-WAN
  • 78% integrated contact center
  • 42% calling plans

  This is really interesting since this has been Sangoma’s strategy for a long time!

  

  We have everything Frost and Sullivan writes about in our chart above. The three to the right on the chart (managed SD-WAN, managed network connectivity, and managed security) were obtained via our acquisition of NetFortris in March of this year.

  And that’s how I’ll end this blog series. Frost and Sullivan validating our strategy.

• ng-voice My 1st month as a DevOps Engineer at ng-voice: Sara

  Who am I?

  My name is Sara Fattouh, and I am going to tell you my story of joining the ng-voice cloud-native team as a DevOps Engineer. I am an informatics engineer, I moved from Budapest, but I am originally from Syria.

   

  After my graduation, I worked as an assistant teacher at the University of Aleppo, where I was responsible for preparing and teaching functional materials in software engineering. I worked in Syria for 2 years as a software engineer, then I was awarded a scholarship to pursue my studies in Budapest, Hungary. While I was a master’s student, I joined Nokia as a trainee, after that, I was offered a full-time position as a software engineer.

  Why did I join ng-voice?

  DevOps engineers have a diverse and unique soft skill set as well as technical skills which are closely linked to the knowledge of the DevOps toolset: coding, and scripting.

   

  I joined ng-voice to embrace and adapt quickly to new responsibilities and I am eager to develop these skills to contribute to the mission of ng-voice: build a fully cloud-native IMS for the market.

  

  Getting settled in a new city

  When I arrived I had a lot of tasks to complete during my first few days, but with the team’s assistance, I was able to obtain a bank account and ‘Anmeldung’ very fast, I started receiving the mail in bulk. It’s Germany, no wonder

   

  I also joined a badminton group to keep the same habit I started in Budapest, playing badminton weekly and making new friends from different backgrounds.  It’s not a secret that in large German cities, finding an apartment is hard for everyone, not only for foreigners. The housing market in Hamburg is quite competitive, but knowing where to look will make your search easier.  There are a lot of real estate websites where new advertisements are published very frequently. I hope that these websites can help me find a suitable apartment to rent shortly.

  My experience as a DevOps Engineer at ng-voice so far

  I had a great time traveling to Germany and joining ng-voice as the staff was accommodating, especially during the visa application process. I traveled from Budapest, spent a 10 days vacation in Berlin, and finally made it to Hamburg. 

   

  On my first day, everyone was very welcoming and I liked every piece of my starter kit which was waiting for me on my desk. A nice onboarding specialist guided me through and helped me with the first steps to settling in the new city. What impressed me from the first day is the high organization, the accuracy, and good documentation of the tasks, not to forget the transparency among the employees. I’ve had a nice experience working at ng-voice in Hamburg overall. Everyone is easy to approach, friendly, and highly responsive. What I like the most about my teammates is how cooperative and eager to help they are.

   

  As a new joiner to ng-voice, I am proud, happy, and eager for more!

• Digium Considerations for a Unified Communications Prem to Cloud Migration

  Some companies are considering the transition from an on-premise unified communication system to a UCaaS system. There could be various reasons, ranging from the age of the prem system, to not wanting to manage the on-site system anymore (manually update the system, etc.), to it being part of your company’s strategy to move as much support systems to the cloud, to you are growing and you want your system to scale better and support remote offices.

  No matter what, there are considerations.

  One consideration is are the features the same? Some UC features are “easier” in an on-prem system, and some features are older and maybe not available on a newer UCaaS system (fax, analog phones anyone?, hot desking/hoteling for example) so if you have some favorite features or key older technology to support, make sure you ask.

  Or maybe you’ve built some of your business processes to work with the on-prem system very tightly. Make sure you ask about that and don’t assume it will work.

  Also, maybe you already paid for your phones, so does the UCaaS system support the phones you have already invested in?

  And you should create a plan once you’e decided to do it. Make sure there is a transition period where the prem system and the cloud system are both there, and start the data migration (voice mails, etc.) first. Then there are the applications that interface to the phone system that need to be migrated over as well. And make sure your network can support this.

  If you are considering a migration, Sangoma is here to help you. Give us a call. We offer both on-premise and cloud Unified Communication systems, and have literally helped migrate hundreds if not thousands of businesses from prem to cloud.

• ng-voice I deployed ng-voice’s cloud-native IMS over a 10 minute coffee break

  As telcos look for new ways to compete in the market and release new products and services to their subscribers, agility, efficiency and speed is vital. In this blog, we’ll explore the process of deploying our cloud-native IMS solution and the critical role that automation plays in the process. 

   

  Picture this:

  It was around 1 am…the time when most people are asleep. For me, however, this time means low network traffic and the perfect time to perform upgrades on network functions providing critical services. 

  I watched my laptop screen closely, hoping to avoid finding any issues during the upgrade process of a Call Session Control Function (a network function in the IMS). There was no room for error, as one mistake could impact millions of subscribers. I wanted simpler, better, faster….

  The above was a common experience in my past working career. However, you will be glad to know that there is a positive outcome. 

  A few months ago, I surprised myself by deploying ng-voice’s IMS over a coffee break. I ran a few commands using Helm, got my coffee, and before I knew it, in less than 10 minutes, the entire IMS solution was deployed in ng-voice’s lab. The summary of this breakthrough is one keyword: cloud-nativity.

   

  Understanding cloud-native principles

  Cloud-nativity is more than just deploying software in the cloud. It is a broad term that incorporates many capabilities. At ng-voice, there are several key cloud-native principles that we adhere to:

  • Infrastructure-agnostic: The IMS core can be deployed on any cloud or bare metal thanks to Kubernetes-based container architecture
  • Balances load: The solution provides load balancing and service-discovery
  • Self-healing: Active monitoring to identify and replace failed components to maintain availability 
  • CI/CD: Automation throughout the integration, delivery and deployment pipelines
  • Automatic scaling: Recognizes load continuously and adapts necessary capacity accordingly

  So, how do these principles work together to enable our IMS solution to be so easily deployed?

  ng-voice’s software is based on a greenfield microservices design, meaning that the system is developed from scratch without the restrictions of legacy infrastructure. This allows us to provide a truly personalized solution, avoid the constraints of monolithic software and ensure we can leverage small-sized containers to maximize efficiency and scalability. 

   

  We also prioritize using a DevOps approach from the start, which encourages faster, more streamlined development and deployment. A crucial part of our DevOps approach is ensuring efficient software lifecycle management through the CI/CD pipeline, bringing developers and IT operations teams together to deploy software more efficiently. The diagram below outlines how our CI/CD pipeline works:

  

  Although it’s possible to manually execute each of the above steps of the CI/CD pipeline, the true value of CI/CD pipelines is realized through automation. With automation as the backbone, the threat of human error is minimized, and a constant process for the testing and release of software can be maintained. 

  Benefits to MNOs, MVNOs, and Private Networks

  Automation brings several benefits to the telecoms industry by deploying cloud-native solutions:

  • Cost-effectiveness: Automation reduces the time to manage and deploy applications thereby maximizing efforts. This is of particular benefit to MVNOs, as they typically have smaller economies of scale, so maximizing their return on investment is critical
  • Increased efficiency:  Through end-to-end automated pipelines, features and software updates are ready for delivery faster and deployed faster. Pre-defined scripts and pipelines ensure that quality is reached in an optimal timeline
  • Scalability: By introducing an automated, cloud-native solution, network operators of all sizes can deploy new services and products quickly and simply, to meet changing subscriber demands and compete in the market. Furthermore, ng-voice’s IMS can be automatically scaled based on traffic demands

  While the benefits are clear, how do they translate in a real-life setting? Here we bring two different deployment use cases.

  Use case 1: Google Cloud

  The deployment of our IMS solution in the Google Kubernetes Engine (GKE) is a clear example of just how much difference automation can make. GKE provides a managed environment for deploying, managing, and scaling containerized applications using Google infrastructure. The GKE environment consists of multiple applications, grouped together to form a cluster, managed by Kubernetes. If one application goes down and another needs to start, Kubernetes will interact with the cluster to ensure this can effectively take place. 

  Deploying ng-voice’s IMS core in the GKE is extremely simple. We recently timed one of our Cloud Engineers and it took under ten minutes to carry out the following steps: 

  1. Install Kubernetes cluster of 3 nodes
  2. Add docker  repository credential to the default namespace
  3. Deploy all of  the network functions using Helm file in one command
  4. Glance back at your laptop and you’ll see that all the components are up and running, ready to connect to your core network
  5. Sit back and enjoy your calls!

  Use case 2: Bare metal 

  But deployment in the GKE isn’t the only environment that showcases the benefits of our solution. These can also be seen in a bare metal environment too. 

  1. The deployment kicks off with the host provisioning stage, of which the timeline depends on the customer
  2. From here, host preparation takes up to fifteen minutes
  3. In another fifteen minutes, the Kubernetes cluster is created
  4. The final step, which is installing the network functions, can be in five to ten minutes per network function
  5. The IMS core is up and running in a bare metal environment

• Digium What is UCaaS?

  Introduction

  Unified Communications as a Service (UCaaS) is a cloud-based solution that integrates communication features, applications, and services into one cohesive platform. By moving to a UCaaS platform, businesses can utilize the cloud’s mobility and scalability while reducing costs and increasing productivity. This article will go over what Unified Communications as a Service really means (and why it matters).

  What is UCaaS

  UCaaS is a term that refers to unified communications as a service. It’s an umbrella term for different communications services, including video conferencing and collaboration tools such as SangomaMeet and TeamHub.

  Businesses can utilize the cloud’s mobility and scalability by moving away from legacy components such as on-premise PBX systems. Additionally, most UCaaS systems enable your business phone number to be used by your smartphone and your laptop, enabling employees to work remotely very effectively.  By moving to a UCaaS platform, companies can save on upfront costs by deploying a pay-as-you-go approach to their business communications. The monthly cost of a UCaaS platform is usually lower than the monthly maintenance and service costs associated with on-premise systems, and there is no capital expenditure required for hardware or software purchases.

  Furthermore, with UCaaS, you don’t need to worry about purchasing new hardware or software every time you want to add new features; instead, you simply upgrade your subscription plan to gain access to new capabilities!

   

  Features of a UCaaS Platform

  A UCaaS platform has several features that make it stand out from other types of business phone systems. Let’s look at a few of the most important ones:
  

  • • Presence: This feature allows you to see which users are currently logged into the system and where they’re located in relation to your office, so you can call them when needed. It also displays indicators, such as, Do Not Disturb, Active, and Out of the Office.  
    • Mobility: The mobility feature allows you to stay connected regardless of your location. Through your office extension, you can make and receive calls, chat, and more with a softphone application on any device with an internet connection—a smartphone or tablet, for example—no matter where they are located as long as they have an internet connection. So you can work from home or from a remote location and still be able to use your office phone number!
    • Collaboration: Collaboration tools are designed specifically for sharing information among team members within one organization; these include chat rooms where people can type messages back-and-forth using text whenever needed instead of calling each other individually over the phone.
    • Unified Messaging: With unified messaging, users can manage many types of messages from a single application and switch communication modes on demand.
    • Video Conferencing: Stay connected with multiple users with conferencing. Conferencing allows a group of users to meet and speak via voice and/or video from multiple locations. This option is also available to outside organizations, partners, or clients. 

  UCaaS Benefits

  UCaaS offers a competitive advantage to businesses by reducing the number of independent tools, platforms, and solutions. It can streamline communications for organizations, regardless of size or industry. Because UCaaS integrates and optimizes all interactions, team collaboration and productivity are significantly improved, and the engagement of sales prospects, vendors, and customers. UCaaS facilitates: 

  • Increased collaboration between teams and departments
  • Improved security through centralized management of various communications devices and apps
  • Reduced costs due to the consolidation of messaging platforms into one centralized service
  • Reduced IT overhead since the cloud subscription enables security and other updates to be done by the cloud service, not by you.

  Why it Matters

  Businesses rely on communication tools to stay productive and competitive, and when it comes to motivating employees and increasing productivity, integrating communication tools empowers workers to handle multiple tasks quickly and efficiently. By integrating communications into one platform, companies can improve team collaboration and productivity while reducing costs.

• Digium How to Deploy or Migrate to UCaaS the Smart Way

  Let’s face it: launching a UCaaS (Unified Communications as a Service) system from scratch can seem pretty daunting. This type of cloud phone system incorporates many different types of communication / collaboration services to help your business succeed. Whether you’re talking about voice, video, messaging, meetings, presence or team-based collaboration, they’re all traditionally available as options.

  And while the hallmark of a UCaaS environment is its ability to bring together all of these elements, there are many (frequently overwhelming) considerations you have to make on the back end to determine if and how it can work for you. Then, there are past investments. Over the years, many businesses like yours have spent significant time and money toward implementing many traditional communication and collaboration options that are now outdated for the modern landscape.

  Previous choices, however, should not complicate matters when considering when, how and why to make that jump to an all-encompassing UCaaS infrastructure.

  Choose the UCaaS for YOUR Needs

  In most cases, your provider may be able to handle the dirty work for you. The key is to select the specific features and elements that your organization needs, and see what sorts of deployment options are available from the host.

  So … whether you’re starting out from scratch or migrating to a full-on – or even hybrid – UCaaS environment, most of this rollout involves the streamlining and automation of a la carte options.

  Consider Scalability …

  Communications and collaboration options abound, but are not all necessary in every business case. From a UCaaS perspective, it can be scaled as necessary, with features added or taken away in an a la carte fashion as your organization’s needs change. In other words, UCaaS allows you to establish custom communications infrastructure exactly as you need while also supporting future growth initiatives.

  For that reason, you should carefully evaluate the options and capabilities made available to you by the various providers, weighing them against your own unique needs.

  … While Embracing Flexibility

  One of UCaaS’ best traits is how optimal it is for remote and telework environments. This cloud-based system can be deployed across many different types of communication channels and devices. The flexibility it extends to YOUR deployment, however, should run so much deeper.

  In particular, focus on factors such as extending customer communications channels and streamlining CRM services with these options.

  Assessing Reliability

  With flexibility comes the need for reliability, a factor that can largely be out of many organizations’ control. Sadly, the stability of a UCaaS is largely tied to the state of your – and your remote workers’ – internet connection, as well as the relative strength of the service provider and UCaaS architecture that it provides.

  In most cases, the smart move is to choose a deployment that guarantees virtually unlimited uptime and availability, as well as geo-redundancy for better backup integrity. Many vendors claim accessibility to these. Reading customer and peer reviews, however, can often tell a different story.

  Focus on Real Time

  UCaaS users tend to be the most productive when they can communicate and collaborate consistently in real time, as if seated in the same room as one another.

  Weigh Cost Versus Benefit

  Like most extensive software deployments, the price tag will almost always play a factor. Choose a UCaaS system that gives you the most proverbial “bang for your buck,” weighing the critical features that you need against the feasible cost of their implementation.

  While it’s often good to take a chance, gaining access to the most sought-after features and elements for the lowest-available cost is almost always prudent.
