    Kamailio – 15 Years of Development

    Fifteen years ago, on September 3, 2001, inside Fraunhofer Fokus Research Institute, first commit to the source code repository of Kamailio has been made by Andrei Pelinescu-Onciul:
    Here are the references to the first three commits:
    # git log --pretty=format:"%h%x09%an%x09%ad%x09%s" --reverse | head -3
    512dcd9 Andrei Pelinescu-Onciul Mon Sep 3 21:27:11 2001 +0000 Initial revision
    888ca09 Andrei Pelinescu-Onciul Tue Sep 4 01:41:39 2001 +0000 parser seems to work
    e60a972 Andrei Pelinescu-Onciul Tue Sep 4 20:55:41 2001 +0000 First working release
    The project was initially named SIP Express Router (aka SER), years later – after a fork, a rename and a merge – it converged into into what is now the Kamailio project. It has been a fabulous journey so far, in a more than ever challenging market of real time communications.
    Well known for its performances, flexibility and stability, Kamailio has set a relevant footprint in open source and open communications, enabling entities world wide to prototype, launch new services and build scalable businesses, research and innovate in real time communications. More over, the project has succeeded to create an amazing community of users and contributors, the real engine behind its successful evolution.
    Its time to celebrate the moment, everyone involved deserving it — thank you all!
    In a few months the project will deliver v5.0.0, its 16th public major release, with a restructuring of the source tree to match current modern approaches and more flexibility in choosing the language for building the desired SIP routing rules. Stay tuned!
    Thank you for flying Kamailio!

    VUC – SER-Kamailio At 15 Years

    This week on Friday, September 2, 2016, we will join the VoIP Users Conference (VUC) moderated by Randy Resnick for an open discussion about the evolution of Kamailio project.
    On September 3, 2001, the fist commit was pushed for what was then SIP Express Router (SER) project at Fraunhofer FOKUS Research Institute in Berlin, Germany, project that evolved over the time in what is now Kamailio.
    A lot of great things happened along the way, there were also some not-very-pleasant moments, but hey, that’s life! Join us to listen or share such moments — if Kamailio made your live easy or bad, if you have a funny story to tell or a photo/video to share, you are welcome on board!
    We started the celebration at Kamailio World Conference 2016, now we gather online of a non-technical debate of whether the project succeeded to deliver on its promises.
    Several people already confirmed the participation, like Alex Balashov, Daniel-Constantin Mierla and Fred Posner. We expect VUC regulars such as James Body to be around.
    Anyone can connect to VUC and listen audio or watch the video session via SIP or YouTube live streaming. For more details see:
    Should you want to actively participate in the discussion, contact us via email at registration [at] in order to plan a bit the structure. Last minute joining is also possible, but a matter of capacity for the video conferencing system.
    Thank you for flying Kamailio!

    SIPit 32

    The next SIPit – the SIP Tnteroperability Test Event – will be held at the University of New Hampshire Interoperability Laboratory, in Durham, New Hampshire, USA, during September 12-16, 2016.
    SIPit facilitates testing your SIP implementations, gathering of SIP professionals that develop phones, PBXes, servers or other SIP application to enable peer-to-peer an multiparty tests.
    There is a great testbed of various NAT networks for those of you working with NAT traversal issues, including IPv6 in the network as well as an extensive set of tests for TLS. This year, there will also be a focus on STIR – the new secure identity handling in SIP.
    Olle E. Johansson explains why you should participate in the next slides:
    To register and learn more details, go to the main SIPit web site:
    Along the past 15 years, Kamailio-SER participated at many of the SIPit events, which is reflected in the robustness of the application. This edition, at least Olle will be again there to ensure the latest version stays rock solid.
    Many of the automatic tests on site are built using Kamailio, go there and hammer it!
    Thank you for flying Kamailio!
