| 12:20-12:30 ♦ Welcome Note |
| 12:30-17:20 ♦ Technical Workshops |
| ♦ (Workshop) Kamailio For IMS – VoLTE |
| Carsten Bock, CEO NG Voice, Germany |
| An overview of the extensions offered by Kamailio for building IMS and VoLTE core platforms, with examples for various use cases, different IMS node types (I-CSCF, P-CSCF, OCS, ISC, S-CSCF, …) and integration with WebRTC. |
| ♦ (Workshop) Homer: From Zero To Hero |
| Giacomo Vacca, Owner RTCSoft, Italy |
| Homer is an Open Source tool for real-time analysis and monitoring of VoIP and RTC platforms. It supports all the major OSS voice platforms, it’s modular, easy to install and scales to carrier-grade infrastructures. Homer goes beyond collecting and correlating signalling and logs, and can also capture RTCP reports, QoS reports, and other events. Through an ElasticSearch endpoint, Homer supports BigData analysis of traffic.
This workshop focuses on the deployment of a multi-node Homer framework with various approaches: bash installers, Docker containers, Puppet. We’ll see how to configure Kamailio, FreeSWITCH (including the ESL interface), RTPEngine, Janus gateway (Events API), to collect signalling, RTCP reports, app-specific events and have them correlated and presented in a user-friendly GUI. For advanced users, we’ll present the installation of captagent, the standalone capture agent, hepgen.js to generate test traffic, and a Wireshark dissector to have full visibility of data flows. |
| 14:30-15:00 ♦ Break |
| ♦ (Workshop) Load Testing Of SIP and WebRTC Infrastructures |
| Lorenzo Miniero, Co-Founder Meetecho, Italy |
| Several tools exist for the stress and load testing of SIP infrastructures. Whether the purpose is to only test signalling, or involve media as well, there usually is a solution that can help achieve the desired result. When the SIP infrastructure is WebRTC based, though, this becomes a less trivial problem. In fact, generating a lot of legitimate WebRTC traffic is complex, and simply replaying previously captured traffic would break the security constraints imposed by all the involved protocols (ICE, DTLS, SRTP). This talk aims at providing an overview of the solutions already existing and widely used for SIP/RTP, and show how the approach must be refocused once WebRTC comes into the picture. |
| ♦ (Workshop) Cloud API For SIP Devices Management |
| Sherman Scholten, Obihai, USA |
| A presentation about device management cloud APIs and the relevance to network agnostic deployments of VoIP endpoints (phone or fax adaptors and IP phones). How it can improve user experience, ensure seamless firmware upgrades for security and new features, and facilitate operations for large VoIP services. |
| ♦ (Workshop) Kamailio Configuration Optimizations |
| Daniel-Constantin Mierla, Co-Founder Kamailio, Romania |
| A practical tutorial about the tools and mechanisms offered by Kamailio to optimize the execution of SIP routing scripts: caching systems and fast indexing of large data records, tips and tricks about SIP routing logic, smart execution control, benefits and drawbacks of various optimization options. |

| 09:30-10:00 ♦ Kamailio On Air! How Sveriges Radio Use Kamailio In Live Radio Broadcasts |
| Olle E. Johansson, CEO Edvina, Sweden |
| EBU, the European Broadcast Union, has standardised on using SIP as an infrastructure for radio broadcasting. The Swedish national public radio has built a next generation broadcast platform based on Kamailio, BareSIP and an in-house platform for managing the system. The talk will describe how this new platform is built, how it is used on in-house networks as well as mobile and remote Internet connections. The talk also describes how the new platform has changed how radio is produced – the transition from old ISDN technology to a IP based system with built-in support for mobility. |
| 10:00-10:30 ♦ Kamailio And Next Generation Emergency Services |
| Wolfgang Kampichler, Frequentis AG, Austria |
| Next Generation Emergency Services are designed to close the gap between the quickly evolving technologies (fixed and mobile IP-based communications) and the more conservative approaches required by the emergency communications industry. This presentation provides a comprehensive overview of the architecture envisioned and standardized for NG emergency services. An important functional element of this architecture is the emergency services routing proxy (ESRP), which is the SIP entity that makes decisions about the call routing by using service URNs, location information and domain specific routing policies. Kamailio, as feature rich, reliable and performant communications platform is well suited for such scenarios, therefore, this contribution gives also a deep insight into the process of next generation emergency call routing utilizing Kamailio. |
| 10:30-11:00 ♦ Coffee Break |
| 11:00-11:30 ♦ RTPEngine Media Processing For Fun And Profit |
| Andreas Granig, Sipwise, Austria |
| The Sipwise rtpengine for Kamailio provides various ways to analyze and process RTP flows for ongoing calls. This talk describes the concepts to report the quality of calls in real-time to Homer, to store raw RTP packets to PCAP files, and to record plain and encrypted audio call streams for standard SIP and WebRTC calls in WAV and MP3 format. |
| 11:30-12:00 ♦ Meshing and Virtualizing of IMS and EPC with Kamailio |
| Dragos Vingarzan, Core Network Dynamics, Germany |
| Leveraging the work done during the past decade with IMS and EPC in research as well as industry, this presentation is highlighting how these technologies can enable the operators to extend their offers beyond the traditional telecom services. |
| 12:00-12:30 ♦ We Have Got The Wizardry, What Now? |
| Dan Jenkins, Nimble Ape, UK |
| Why build any experience that isn’t magical for your user? Building anything truly extraordinary used to be really difficult; but today we can do it in a few hundred lines of code. But can you truly say you’re offering your users the most spellbinding experience possible? It’s doable today but we’re not doing it everywhere yet.
Natural Language processing, Real Time Image processing and speech recognition APIs; they’ve all moved forward at a rate of knots in the past couple of years. What used to require huge investment in hardware, software and talent is now available to everyone who can write a few hundred lines of code. Even though we have huge power at our fingertips with cloud and browser based APIs, we aren’t truly utilising this technology to make a meaningful difference to our customers, users and our businesses today. Building for tomorrow is difficult when we’re still thinking about yesterday. In this session you’ll learn about the APIs available to you today and how you can make a difference to what your applications are doing to build relationships with your users. Developing that connection with the user can be magical. Give your user magic. |
| 12:30-13:30 ♦ Lunch Break |
| 13:30-18:30 ♦ Conference Presentations |
| 13:30-14:00 ♦ Why I Love Kamailio |
| Fred Posner, LOD, USA |
| From large scale deployments to Raspberry PI systems, there isn’t much that Kamailio can’t cover. The software has come a long way, and yet there’s so much more we can do as a community to give back to the product. |
| 14:00-14:30 ♦ Why IVR Is Essential To RTC |
| Allison Smith, The IVR Voice, Canada |
| IVR is often seen as a necessary evil; an often abrupt and unwelcoming gateway to a company. Industries are realizing that their IVR sets the tone for callers — it tells them everything they need to know about the company and what it will be like to deal with them. It is essential that the outward-facing IVR on your RTC system (with Kamailio or without), is intuitive, easy to use, and presents your company in the most positive light. |
| 14:30-15:00 ♦ The Strategy And Technical Mechanics Of Building A VoIP Global Network |
| David Casem, Telnyx, USA |
| The internet is great for non-RTC based web applications. When it comes to telephony however, the fact that packets take the cheapest path – not the shortest – means that latency and packet-loss sensitive packets are exposed to not only degradation, but possible interception.
By leveraging cloud infrastructure, containerization, and a highly efficient VoIP PoP design, Telnyx has successfully shortened the length of the “last mile” by quickly taking packets off the internet and putting them on an MPLS-TE backbone. In doing so, not only we protect better users’ packets, but ensure uptime through geographic diversity, redundancy and resiliency. In this presentation, you’ll learn why and how Telnyx built a global, cloud agnostic network and the tooling used to deploy and manage it. |
| 15:00-15:30 ♦ Routing On The Host And Anycast SIP |
| Simon Woodhead, CEO Simwood, UK |
| The network is a strategic asset that can make a difference to your end-users’ communication experience. While most of VoIP platforms rely on unicast routing, here we show the advantages and how to build a SIP anycast routing for optimum node discovery, redundancy and scalability. |
| 15:30-16:00 ♦ Coffee Break |
| 16:00-16:30 ♦ What Is New In Asterisk |
| Matthew Fredrickson, Digium, USA |
| A few months ago, we closed out the year and Asterisk 14 was released. This talk is to take a look at Asterisk’s development, what’s going on there, and where the project is heading from a technology perspective, what are the new features and tools that can be used to leverage Asterisk for VoIP platforms and integrate it with other RTC components. |
| 16:30-17:00 ♦ Billion Calls With A Modern Stack |
| William King, Chief Architect, Flowroute, USA |
| In the realm of real time communications and messaging, what are some of the attributes of a modern software stack? From the perspective of a telecommunications operator and US CLEC, this presentation will cover topics such as containerization, test-driven development, continuous integration plus deployment, logging and introspection, service registry and discovery, and load testing, and how these minimize dev-ops response latencies. Understanding the problems addressed strategically by a modern software stack provides the foundations for building tactical responses to dev-ops challenges. |
| 17:00-17:30 ♦ Building A Modern Doorbell With A $9 Device And WebRTC |
| Tim Panton, |pipe|, Germany/UK |
| Learn how to build a doorbell using the Pi-zero-w $9 Linux machine, solving the following problems: 1) setup and config – how do you get a wifi password onto a device with no keys? 2) pairing – how do you get a device to identify itself and it’s owner? 3) network transparency – how do you get through a complex NAT? 4) notifications – how to wake a smartphone 5) media transfer – how to talk with your visitor. As usual there will be a stupidly dangerous demo and lots of VoIP tools will be (mis) used. |
| 17:30-18:30 ♦ Open Discussions Panel – VUC Visions |
| Randy Resnick, VUC, France |
| What is new and exciting in the real time communications? What will be there in one or two years from now? Open discussions with a selected group of guests. |

| Marius-Iulian Corici, FhG Fokus Institute, Germany |
| An overview of the testbeds and platforms for 5G offered by Fraunhofer Fokus Research Institute, generally available for industry or academic entities, what they offer and how they can be used to plan, test and assert feasibility of new ideas for the future of communications. |
| 14:00-14:30 ♦ Getting Started With WebRTC |
| Chad Hart, Voxbone, USA/Belgium |
| Starting with an overview and brief history of WebRTC, a 5-year-old real time communications technology, this presentation will look at WebRTC use cases in modern communications. Chad will show how you or your company can get started with WebRTC and implement APIs while being aware of the back-end considerations and challenges. |
| 14:30-15:00 ♦ RTC-TIE: Building an RTC Threat Intelligence Exchange |
| Alexandr Dubovikov, QSC, Germany |
| Unlike other industries, the VoIP and RTC ecosystem lacks an accessible network for threat intelligence, leaving many Operators on their own reinventing the security wheel. It’s time for our Community to secure itself with a real-time trusted, voluntary, federated Pub/Sub Exchange, instantly exposing Attackers, Abusers and new Threats, acting as an open and distributed Lock natively integrated at the core of our favorite stacks. |
| 15:00-15:30 ♦ Diameter Processing with Kamailio |
| Carsten Bock, NG Voice, Germany |
| While SIP is a common protocol for Kamailio, Diameter is not. Diameter Processing was heavily limited to be client-side operations in Kamailio, e.g. acting as Client for an Online-Charging System or for requesting QoS in an VoLTE network. Until now. Apart from our Online-Charging-Server module (which we added last year), we recently added a generic Diameter-Processing Module to our beloved and long-term friend and SIP-Proxy Kamailio. Diameter-Processing in Kamailio? In this talk I will sched some light on the development, the goal and capabilities of this development. |
| 15:30-16:00 ♦ Coffee Break |
| 16:00-16:30 ♦ Listening By Speaking – An Under-Estimated Security Attack On Media Servers And RTP Relays |
| Sandro Gauci, Enable Security, Malta/Germany |
| In this presentation we take a look at a vulnerability affecting a number of media servers, some of them being often used together with Kamailio. The vulnerability allows hijacking of the RTP stream without a typical man-in-the-middle attack. We include demos, packet captures and other fun and practical ways to explain the vulnerability. Then we will assess the impact of such a vulnerability as it affects traditional media gateways for VoIP systems as well as the WebRTC infrastructure. Finally we discuss potential solutions and hopefully have a bit of a Q&A too! |
| 16:30-17:00 ♦ Kamailio As A Stateless, Containerized Session Border Controller |
| Jan Lorenz, Pascom, Germany |
| This specific use case presentation demonstrates how Kamailio can be used as a containerized, stateless session border controller whose main mission is to protect and defend an existing Asterisk infrastructure from the inherently dangerous and nefarious internet. |
| 17:00-17:30 ♦ Kamailio.cfg Scripting Languages |
| Daniel-Constantin Mierla, Co-Founder Kamailio |
| Since v5.0.0, Kamailio allows several scripting languages to be used for building SIP routing logic. From the old-good native scripting language, to Lua, Python or JavaScript, one can choose the language that is more suitable for own needs. Besides the flexibility and extensive list of extensions coming with Python, Lua or JavaScript, with some of them (Lua and JavaScript) it is also possible to reload the config routing script without restarting Kamailio. The talk will reveal the benefits and limitations for all these scripting languages that can be used inside kamailio.cfg. |
