EventsThe annual Cluecon conference, an event focused as usual on open source telephony and real time communications, starts soon in Chicago for the 10th edition, during August 5-7, 2014.  Make sure you meet Kamailio developers and users if you attend the conference!

Expect many from our project environment to be there speaking or in audience. Also, be sure you don’t miss Alex Balashov, from Evariste Systems and member of Kamailio project management team, who will give a presentation with tips and tricks about Kamailio on the 6th of August at 15:30.

Definitely an event one should attend, giving the opportunity to get in touch and learn updates from developers of other popular open source projects such FreeSwitch, Asterisk, Jitsi or Kazoo. Also, take the chance to connect with friends of our project from Truphone, Simwood, Ziron, Star2Start Networks, 2600hz or Aeriandi. Security is a hot topic (as always), Phil Zimmermann and Alan Johnston will be there to discuss the challenges and possible solutions.

June 2nd, 2014

EventsWant to learn more about the inside of Kamailio? Next Kamailio Development Workshop takes place in Paris, France, during July 9-10, 2014.

The coordinator of the workshop is Daniel-Constantin Mierla, co-founder of Kamailio project, the entire event being organized by Asipto, Germany and Orange, France.

The goal of the event is to present how to write your own extension in C 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

  • 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

In other words, main outcome of the workshop is developing on site a sample module that exports new parameters, functions, RPC commands, pseudo-variables, deals with locks, private and shared memory, accesses SIP message attributes and updates SIP message content, a.s.o.

The price per attendee is 240 Euro.

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 has to be done via email at:
