Kamailio World 2019 – Registration Is Now Open

The registration for the 7th edition of Kamailio World Conference is now open! More details and registration forms are available on the website:
Like at the previous editions, the event spans over three days, May 6-8, 2019, taking place at our usual venue, in the hearth of Berlin city, Germany. The first day contains the technical tutorials, the following two days are for conference presentations and exhibition.
With this edition, we are introducing a new social networking event during the evening of the first day, the 6th of May. The goal is to allow more time for interaction and networking between participants, as well as get a taste of Berlin. Therefore, this event is organized outside of the conference venue, couple of options being considered at this time, like city tour by boat or double deck bus, pub or pizza party. The cocktail party will take place as usual, during the evening of the 2nd day, the 7th of May. More updates about this new social networking event in the near future!
Note also that the Call For Speakers is still in progress and we already have a consistent group of submissions, if you plan to present at Kamailio World 2019, hurry up with the proposal! Scalability and security, WebRTC, IMS and VoLTE or IoT with Kamailio as well as related projects such as Asterisk or FreeSwitch are among the topics to be covered this year.
Keep an eye on the website of the event, soon we will publish more details about accepted speakers and the first draft of the agenda.
Looking forward to meeting many of you in Berlin at Kamailio World 2019!

Planning Fosdem 2019

Fosdem 2019 is approaching, so we surveying to see who from the community plans to go to the event. We also plan to organize again a dinner on Saturday evening, a tradition for our project at the past 10 editions or even more.
Henning Westerholt will give a presentation about Kamailio in the RTC Devroom.
Several other developers plan to go to the conference as well, among them Daniel-Constantin Mierla, Federico Cabiddu and Alexandr Dubovikov, therefore we open here the invitation to join for everyone in our community. Of course, at Fosdem will be developers from other VoIP projects, like Asterisk, Janus, CGRates, Homer, Jitsi, …
At the past editions we typically had two “kamailio” events:
  • (1) an “ad-hoc” developers meeting in the cantina (or other available
    room around) to discuss about short term plans for Kamailio — time and
    place being decided as we meet there between us (expected in the
    afternoon of Saturday or during Sunday).
  • (2) a dinner at a place nearby, with other VoIP folks joining us
If you plan to go to Fosdem and want to join the dinner, announce yourself on sr-users@lists.kamailio.org mailing list. Just be aware that you have to pay for your food and drinks at the dinner, unless we are going to be surprised again by a generous sponsor that covers partially or completely to dinner.
If you need more details about Fosdem, the website is:
