Kamailio World 2016 – May 18-20, in Berlin

The next edition of Kamailio World 2016 is planned to take place in Berlin, Germany, during May 18-20, 2016. We are now analyzing if there are potential major conflicts with other events — if no update in the next few days, then the dates and location are final!


It will take a little while until we will open the call for speakers and registration, however, worth to mention by now that next year the Kamailio project celebrates 15 years of development. We expect a larger number of participants as well as special guests, therefore it is highly recommended to submit proposals as soon as the process is open.

The event is hosted again at Fraunhofer Forum, in the heart of Berlin, like the past editions. Additional space was rented to be able to accommodate better the exhibition and the services for participants.

Keep an eye on kamailioworld.com for updates!

Looking forward to meeting many of you in Berlin next year!

Kamailio World 2015 – One Week Before

kamailio-world-ddOne week before and we are ready to welcome the guests of the 3rd edition of Kamailio World Conference & Exhibition.

The content is filled with excellent technical tutorials in the first day and vast range of hot topics covered during the two conference days — Kamailio, SIP, WebRTC, Asterisk, Sems, JsSIP, Performance and Traffic Monitoring, OpenStack, Kazoo, Erlang, Cloud PBX, OTT or VoLTE are among them.

We are honoured to have an impressive list of speakers, from those that are involved in building the communications, able to share their expertise from deep technical aspects to market needs and business perspectives.

Over all, the event has grown continuously from its first edition, special thanks to our sponsors : FhG Fokus, FhG Forum, Asipto, Sipwise, sipgate, Simwood, Obihai, Matrix, Digium, Tyntec, NG Voice, CoreNetDynamics, Pascom, VoiceTel, 2600hz and VUC.

This is an event you must not miss!

Looking forward to meeting many of you next week in Berlin!


Kamailio World 2015 – The Schedule

It is one month till the start of Kamailio World 2015, time has passed very fast since we announced the event, accelerated by April filled with many public holidays.

The first draft of the schedule is now available, as usual, expect many speakers to tune the content of their presentation along the way to the day of the talk, to surprise the audience with challenging concepts and visions.


At this edition we were pleasely surprised by the number of submissions, but it was an extremely hard task to select the sessions. To accommodate as much as possible, we are introducing the lightning talks, two of 10 minutes each, to give the opportunity to present shortly about interesting ideas or updates of applications used in Kamailio and VoIP eco-system.

The two days of conference are filled with 28 sessions, the event being completed with 5 technical workshops during the pre-conference day. Several exhibitors will be available during the conference days with showcases of their products or solutions, ready with many demos on site.

We are very grateful to our sponsors, which made possible to bring again a consistent number of speakers, ensuring first class quality content for the entire event.

In about 4 weeks, we will be ready to welcome you in the beautiful city center of Berlin. Don’t miss the opportunity to attend this event, it is unique across Europe, bringing open source and real time communications industry together, bridging flexibility innovation with telecommunication businesses. It is now the right time to register!

See you in Berlin at the end of May!

Kamailio World 2015 – The Workshops

It is now about one month and a half till the start of Kamailio World Conference 2015. Continuing with the same event structure like in 2014, the afternoon of the first day, the 27th of May, is filled with several technical workshops. These sessions are intended to give a more hands-on perspective on the subjects, with deeper technical content.


Last year, Sipwise showed how to deploy sip:provide CE – the open source out of the box IP Telephony Operator Platform – in a matter of minutes and customize it to fit better your needs. This year, Daniel Grotti, a long time SIP and Kamailio fellow, is going to show how to enable WebRTC for sip:provider CE in order to bridge the communication between the web world and the classic SIP phones. Few other typical use cases will be approached during the session.

Carsten Bock, from NG Voice, is returning with another tutorial to show more of what can be done with Kamailio for IMS and VoLTE deployments. Besides the tutorial, the plan is to have a VoLTE testbed on site for the duration of the entire event, so the participants can test with their own devices.

After presenting at the past editions the concept and the development of CGRateS, a carrier grade open source CDR rating engine, Dan Bogos is now coming with a hands-on session about how to integrate it with Kamailio for prepaid and postpaid billing.

Ability to troubleshoot SIP routing and analyze the flows on the wire is one of the core elements required for VoIP engineers. Lorenzo Mangani, one of the co-founders of Homer SIP Capture project, is going to deliver a session on how to use existing open source tools (including Homer and sipgrep, but not limited to) to make the SIP troubleshooting process easier.

Click-to-dial has been the most notoriously referred example to demonstrate and integration of web-services with telephony and became a “hello world” example application. Nevertheless numerous methods have failed to gain adoption due to various integration difficulties. CTI APIs was forgotten before it started because of too many vendor ties, B2BUA-based call-control didn’t gain traction because the simple feature wasn’t worth the trouble, and REFER-based CTD was not even understood by many vendors. With WebRTC the situation is different: the integration falls aside, as web client speaks its own language with server. With current infrastructure technologies available out there, elasticity is the key factor that balances between costs and short time scalability demands, defining the profitability. It is time to show how to build a Javascript-based client backed by openstack-powered infrastructure in a simple step-by-step manner, which can be used as getting started reference for building more complex services.

All together are providing an amazing amount of knowledge from the people with first hand experience, those that built the systems. It is a unique opportunity at Kamailio World to get face to face to interact with such people.

The content of conference days is filled with other very interesting sessions, including as well valuable technical details, presenting scalable and secure architectures or other products that can be used to complete the VoIP platforms with new features. Right now you can see details for a sections of presentations in the Schedule page.

Be sure you don’t miss Kamailio World Conference 2015, during May 27-29, in Berlin, Germany – it is the open source real time communications event in Europe!

Secure your participation and register now!

See you in Berlin!
