There can still be changes in the timelines, therefore keep an eye on the website for latest updates.
At this edition we have again sessions covering the major open source SIP/VoIP projects: Kamailio, Asterisk and FreeSwitch, as well as industry perspectives from a consistent group of renowned speakers. You can learn about the impact of 5G for local network innovations or how to build 4G networks with open source; scalability, reliability and security are well covered across many workshops and presentations; how to use latest Homer SIPCapture or what is new in Asterisk along with the no-touch auto provisioning system for FreeSwitch.
More relevant projects are represented, such as Wazo, dSIProuter, reSiprocrate, Janus Gateway, CGRateS, SIP3.io; differences on voice and video media processing; WebRTC – how to build a softphone with web technologies; the RTPEngine project developed at fast pace in the past two years, adding transcoding, call recording, audio play back and more, the talk about it is something that should not be skipped.
Three interactive sessions complete what looks like being the most impressive content of a single Kamailio World edition to date, respectively the traditional VoIP Visions panel, Dangerous Demos and the new show Your Deployment On Stage. The conference content is accompanied by two social events in the evenings on Monday and Tuesday: Berlin City Boat Trip and Cockatail Party.
Kamailio SIP Server v5.1.8stable is out – a minor release including fixes in code and documentation since v5.1.7. The configuration file and database schema compatibility is preserved, which means you don’t have to change anything to update.

Luis Martin Gil from zaleos.net has published a blog detailing how to create a new module for Kamailio using C++. Although Kamailio is written in C, sometimes C++ can be a more convenient programming language for a module, especially if it needs to link against an external C++ library. Another useful benefit can be the ability to use existing unit testing frameworks. These and other benefits are detailed in the article published at:
Besides bringing a consistent group for distinguished speakers, with every edition we aim to improve the interaction between all the participants. From the first edition of the event we had the VUC Visions panel and Dangerous Demos, along with the cocktail party for social networking. At the previous edition we introduced the Ask Me Anything session with Kamailio core developers.
In 2019, we are adding two new sessions to offer even more chances that the participants know each other and network between them, opening the doors for partnerships and collaboration. These are:
Your Deployment On Stage – 5 Minutes 5 Slides – the session is coordinated by Markus Monka, head of IT infrastructure at sipgate.de. In this session any participant can come in the front of the others and speak about how they use Kamailio or what they are offering in the VoIP/RTC space. Think of it as a quick exposure, letting the others notice your presence so they can approach during the breaks or social networking event for further discussions. Time is limited, the proposals will be accepted in the order they are received. You can contact us starting now and get your 5min — use the web form for it. Important note: this session is not for accepted speakers, but for the registered attendees.
Berlin City Tour By Boat – with special credits to sipgate.de for sponsoring it, this new social networking event during the evening of May 6, 2019, aims to offer a relaxing time combine sightseeing in the beautiful city center of Berlin with enjoying a few drinks, overall enabling more chances to chat between us.
Looking forward to meeting many of you in Berlin at Kamailio World Conference 2019! You still have the chance to secure your seat now at the early registration fee:
