Kamailio World is the Open Source Communication conference in Europe this spring!

From web site:

Kamailio World will be THE conference to attend for everyone in Europe that works with Open Source communication – from classic PSTN over IP, VoIP to realtime communication platforms! While the conference is focused on Kamailio, it also covers related projects like SEMS, Homer SIPcaptureAsterisk and FreeSwitch and how they relates to small and large Realtime SIP platforms with Kamailio!

Where the European SIP engineers meet!

The Kamailio World conference will be the meeting place for everyone that works with Open platforms for realtime communication in Europe. Many projects, many companies and many people meet for a couple of days to share experiences, mingle and brainstorm about new ideas. Open Source Realtime software is used everywhere, from small businesses to large carriers. After ten years of development, there’s still quite a lot going on with new solutions, new devices and new technologies like Opus, WebRTC, SIP Outbound, WebSockets and much more. Register today and be part of the first Kamailio World conference!

Case studies, new software, cool projects – we’re covering it all!

The list of speakers includes the project leader and founder of Asipto, Daniel-Constantin Mierla, Carsten Bock who has worked with Kamailio and carrier IMS platforms for a long time,  Olle E. Johansson, Asterisk and Kamailio developer, consultant and trainer, Stefan Wintermeyer – the creator of the Gemeinchaft Open Source PBX based on FreeSwitch and many more. Read the full list on the conference web site!

The conference is in Berlin, April 16-17 2013! The Voip Users Conference, VUC,  is the media partner covering the conference. Randy Resnick, the VUC Grand Old Man will be at the conference both speaking and doing live coverage from the conference floor!

Registration is open – see you in Berlin!

Kamailio Development Workshop, Feb 14-15, 2013, Alicante, Spain

Want to learn more about the inside of Kamailio? Next Kamailio Development Workshop takes place in Alicante, Spain, during February 14-15, 2013.
The event is organized by Asipto and University of Alicante, Master’s Degree in Telecommunication Engineering.

The coordinator of the workshop is Daniel-Constantin Mierla, co-founder of Kamailio project. The goal of the event is to present how to write your own code for Kamailio SIP Server. Note that it is not a training for VoIP administrators looking to learn how to configure and operate Kamailio-based SIP-VoIP platforms.

During the two days in the workshop, following topics will be approached:
  • internal architecture
  • SIP parser
  • memory manager
  • locking manager
  • database API
  • config file language interpreter
  • RPC interface
  • pseudo-variables and transformations framework
  • internal libraries
  • module interface – write your own extensions in C as modules
  • documentation docbook format
The price per attendee is 140 Euro. The participants going to Kamailio World will get a 30Euro discount to the registration fee for the conference in Berlin.

Number of seats to the workshop is limited and access will be granted in first come first served fashion. Registrations or requests for more details must be done via email at:

registration [at]

For people that happen to be in the area but not interested in programming C and/or not participating to the class, there will be a Social Networking Event during the evening of Feb 14, where we meet for food, drinks and discussions about SIP, VoIP and more.

Participation to the evening event is open and free for anybody, very likely to be a dinner or a pub session where every participant pays for himself/herself. Registration is still required so we know how many seats to reserve and send you the location of the event.

Development is frozen for Kamailio v4.0.0

Last midnight was the term to freeze the development for next major release v4.0.0. For a while, the GIT master branch should get only commits related to bug fixes, documentation improvements and updates of the additional tools.

If any developer needs to store code of new features in the repository, he/she has to use personal branches (or temporary branches in tmp/ when many developers work on the same code). After unfreeze, these branches can be merged in the master branch. Therefore, what is now in master branch will be the code base for v4.0.0, after release the config file you build now will just work.

For 1-2 months from now on, the main focus with the master branch is testing. The v4.0.0 will be out after mid of February, 2013, exact date to be set later based on the results during testing phase.

There were many additions, so any kind of help testing is very appreciated. Fortunately the core and most of the very used classic modules were not changed much, ensuring good stability. But there are old very used pieces such as usrloc/registrar that got touched as well, so try to test as much as possible the components you are using in your configs.

Many brand new additions should give enough reasons to look at v4.0.0:
  • no more duplicated modules – Kamailio-SER integration has been completed
  • websockets support – make calls between web browsers directly through Kamailio
  • IMS modules (about 10) are part of the distribution
  • SIP Outbound extension
  • embedded provisioning interface
  • … for more see the draft of what is new in devel version
Please provide any kind of feedback on sr-dev mailing list or the bug tracker.

FOSDEM 2013 – Free, open, secure and convenient communications


Another edition of FOSDEM is getting close, many Kamailio folks will be at the event, something that got a tradition in the past year. As I type here, people are discussing on mailing list about another get together dinner.

We hope to have a presentation in the Telephony devroom, Peter Dunkley is planning to present how to use the websockets support in Kamailio, which allows calls from web browsers to go directly through Kamailio, without any additional server software.

This year Kamailio will be represented in the main tracks as well. Daniel-Constantin Mierla, co-founder of Kamailio, will be part of a panel about Free, open, secure and convenient communications. The session is scheduled for Sunday, 14:00-14:50, Feb 3, 2013, in amphitheater Jason.

The other participants in the panel are: Daniel Pocock, author of Lumical, Peter Saint-Andre, author of XMPP specification at IETF, Emil Ivov, author of Jitsi, Evan Prodromou, founder of StatusNet and Simon Tennant, the team leader of BuddyCloud.

Be sure you join the session and the debates about the challenges in the open communications. Why VoIP interconnect is not as easy as email? Are there viable alternatives to Skype, Twitter, Facebook or other popular walled-garden services? What can be done to make more popular the services based on open source and open standards?

You can read an interview with Daniel Pocock about this session at FOSDEM web site.

Next Kamailio major release to be v4.0.0

The next major release of Kamailio will be versioned 4.0.0. The release series 3.x took care of Kamailio-SER integration, now that is completed, there is no duplicated module anymore.

Besides finishing the integration process, next major release brings several other very important additions:
  • websockets support – a new transport layer that allows calling through Kamailio directly from web browsers
  • IMS extensions – the IMS related modules are part of the main branch (about 10 new modules)
  • possibility to add ICE candidates to SDP when using RTPProxy for media stream relaying
  • over 10 new modules from the merged SER flavour
  • several other brand new modules, including Diameter peer and embedded provision interface
Freezing of the development for next major release is scheduled for end of Thursday, January 10, 2013. Then follows the testing period, with release target date just after mid of February.

Don’t forget about Kamailio’s first dedicated conference. It is the place where to learn more about the project, how and where to use it, as well as the chance to meet the people involved in the development and management. Read more about Kamailio World Conference at:
