From bare SIP and VoIP, to IMS, EPC, Fokus continues to explore how to evolve, optimize and scale communications between humans as well as machines. With the reach experience of successful projects at all layers of communication stack, the team of researchers at Fokus is now leveraging SDN, NFV and Cloud to offer a complete 5G playgrounds to industry players. The talk is revealing the current hot topics in research and gives a perspective of what to expect in the near future in the RTC evolution.
10:00-10:30 ♦ Building a Programmable Mobile Core Network
Werner Eriksen, VP Communication Services at Telenor Digital
Introducing the flexibility developers want, and opening up the required APIs in a running multi billion dollar operation is not trivial. In a response to this Telenor Digital has built a full stack MVNO setup which from the ground up provides programmability that enables us to build products and services with internal and (soon) external developers.
10:30-11:00 ♦ Coffee Break
11:00-11:30 ♦ Open Discussions Panel – Design And Evolution Of SER-Kamailio Architecture And RTC Services
Moderator, To Be Announced
Discussing the reasons behind SER-Kamailio architecture, what was done right or bad, which of those past decisions will stand today and what can be improved in the future.

Among panelists:

  • Andrei Pelinescu-Onciul – the developer writing the first lines of code for SER back in 2001, main architect of the core, configuration file interpreter, memory manger, etc.
  • Dorgham Sisalem – former manager of Mobis Department at FhG Fokus Institute, the department that started SER in 2001 and did most of the development in the early years of the project
  • Jiri Kuthan – former deputy manager of Mobis Department at FhG Fokus Institute, involved also in writing code for SER (core, tm module, etc.), well known for his raids around the globe to promote the project at various events.
11:30-12:00 ♦ Update Your SIP! A Journey Beyond RFC 3261
Olle E. Johansson, Owner Edvina, Sweden
Much has happened and a few things still need to happen with the SIP protocol since the original v2.0 RFC was published over ten years ago. This talk takes you beyond RFC 3261 and highlights a few additions to SIP that solves issues – and a few we may want to look into soon.
12:00-12:30 ♦ Bridging Kamailio To The Matrix Ecosystem
Matthew Hodgson, Co-founder of, UK
Matrix is an open standard for decentralised persistent communication over IP. It provides simple HTTP APIs and open source reference implementations for securely distributing and persisting JSON over an open federation of servers. Matrix can be used for decentralised group chat, WebRTC and VoIP signaling, Internet of Things data transfer, and anywhere you need a common data fabric to link together fragmented silos of communication. Our focus is on simplicity and security.One of the goals of Matrix is to connect all open communication services together – either natively or via the Application Services (AS) API. This API makes it easy to bridge existing services and protocols into the Matrix ecosystem. Last year, we tried to hack together a Kamailio bridge just before Kamailio World 2015 – this time we have built a proper one by extending the Kamailio server directly!

In this talk we will look at this new bridge and demo calls from Kamailio to Matrix and vice versa. We will also discuss further features and extensions we can add to the bridge, and look at new features in Matrix, such as conferencing and anonymous access.

Matrix is managed by a non-profit open source project acting as the neutral custodian for the standard.

12:30-13:30 ♦ Lunch Break
13:30-14:00 ♦ The Architecture Of Asterisk 13
Matthew Jordan, Lead Developer Asterisk Project, Digium, USA
While Asterisk has been around since 1999, the project is not static, and the open source developers contributing to Asterisk have not been idle. At different points in the project’s history, major architectural improvements have been made that have radically changed the capabilities Asterisk provides to its users. In this presentation, the architecture of Asterisk 13, the latest Long Term Support release, will be discussed. In particular, the talk will focus on Asterisk’s bridging core, message bus, and other internal frameworks that can be used by developers to extend and enhance the open source project.
14:00-14:30 ♦ Your whole network as a [SIP] IPS
Simon Woodhead, CEO Simwood, UK

14:30-15:00 ♦ Interconnecting With Deutsche Telekom Using Open Source Software
Sebastian Damm, Sipgate, Germany
Over the next years, more and more carriers will be urged to switch their interconnections with Deutsche Telekom from SS7 to NGN/SIP. In this talk I will show you how this can be done using just Open Source software. I will also cover some behaviour changes that arise from the switch to the “new next generation world”.
15:00-15:30 ♦ A Tale Of Two Worlds: Bridging SIP And WebRTC With Janus
Lorenzo Miniero, Co-Founder and Main Developer Janus Project, Meetecho, Italy
… or why gateways don’t necessarily have to be seen as pure evil! Janus is an open source, general purpose, WebRTC gateway. Its modular and extensible nature allows it to be used in several different real-time multimedia applications and contexts, ranging from more traditional scenarios like streaming and conferencing to more innovative ones involving heterogeneous devices. One of the available modules enables Janus to act as a WebRTC-to-SIP gateway, thus providing WebRTC users with an easy option for interacting with an existing SP infrastructure. The presentation will first introduce Janus and its architecture in general, to then describe in better detail how the SIP gatewaying feature can be used, and the ongoing efforts to make this even more seamless from a protocol perspective. An overview on existing applications exploiting this functionality will also be presented.
15:30-16:00 ♦ Coffee Break
16:00-16:30 ♦ A Look Back At 9 Years Of Friendly Scanning And Vicious SIP
Sandro Gauci, Enable Security, Germany

12:30-13:30 ♦ Lunch Break
13:30-14:00 ♦ High Quality Telephony Using A Fail-Safe Media Relay Setup
Pawel Kuzak, Core Developer VoIP Infrastructure, 1&1 Germany
With more than 3 millions VoIP customers and over 9 millions registered VoIP numbers, 1&1 is one of the biggest VoIP providers in Germany. For years, we have been focusing on SIP signalling only, using a high-availability Kamailio setup supported by some Asterisk servers providing for comfort services. With the rising number of customers and the advent of possibilities for provisioning Quality of Services (QoS), we had to deal with RTP traffic also. Furthermore, the upcoming IPv6 requires bridging from IPv4 to IPv6 customers. Hence, in 2014, media relays were introduced into our VoIP backend. This talk will show the challenges that arise with this setup, how they have been solved using the Sipwise rtpengine together with a Kamailio (control) proxy, and future perspectives.
14:00-14:30 ♦ Scaling VoIP Network – The good, The Bad And The Down Right Ugly
Nir Simionovich, CEO of Greenfield Tech, Israel
We’ve all designed a VoIP network that required a re-design or a major re-factor at some point. The purpose of this talk is to discuss several methodologies and evolutions of VoIP platforms, specifically, in the service delivery world. We will discuss issues relating to application scaling and not network scaling, as network scaling is fairly simple.This is an in-depth discussion of development methodologies and technologies, targeted mainly towards developers, architects and engineers.
14:30-15:00 ♦ Telephony Evolution At CERN
Francisco Valentín Vinagrero, VoIP Architect, CERN, Switzerland
Sharing the experiences at CERN (the European Organization for Nuclear Research) for migrating its legacy PABX-based telephony system towards a software-based architecture designed to meet tomorrow’s communication needs. With the introduction of open-source call routers and Session Border Controllers (SBC), it is expected to foster the introduction of new services and increase the agility of the telephony network to adapt to new requirements and standards.
15:00-15:30 ♦ Solving the Class 4 Interface with Kamailio
