Kamailio Git Branch 5.1 Created

The GIT branch 5.1 for Kamailio project has just been created, it will host the release series v5.1.x. To get this branch from GIT, you can use:
 git clone https://github.com/kamailio/kamailio.git kamailio
 cd kamailio
 git checkout -b 5.1 origin/5.1
Hopefully in two-three weeks time frame the full release of Kamailio v5.1.0 will be out.
From now on, any corresponding fix has to be pushed first to master branch and then cherry-picked to branch 5.1. No new features can get in branch 5.1. Enhancements to documentation or helping tools, as well as kemi exports are still allowed. If you are not sure about doing or not a backport, ask on sr-dev mailing list.
The master branch can now get new features, which will be part of the future 5.2.x release series.
Thanks for flying Kamailio!

ClueCon Weekly With Fred Posner

FreeSwitch project is running a weekly video conferencing call for many years now, named ClueCon Weekly. Kamailio project has been present several times in the past.
The edition from Wednesday, Nov 8, 2017, has Fred Posner as a guest. Long time Kamailio community member and advocate, Fred invites you to attend the session and be part of the discussions about Kamailio and FreeSwitch, how to use them together for building modern real time communication systems.
How to connect to the conference call is detailed at:
For video you need an WebRTC capable browser, but there are good options to connect only for audio, via SIP or even from PSTN or mobile phone — very convenient ways to listen while still working.

OSS IRIS Broadcast Project Launched

Olle E. Johansson, a very long time community member and developer of Kamailio, has announced the launch of IRIS Broadcast Project, an open source radio broadcast software:
“”IRIS Broadcast is a project founded in Sweden to publish Open Source software for professional radio broadcast.
Our solutions are based on the EBU and IETF standards and are built for national public radio to manage our external contribution platform.””
Olle had a related presentation at Kamailio World Conference 2017 (video), talking about using Kamailio in radio bradcasting industry.
The code of IRIS project is published on Github at:
It includes the repository that shows how to configure Kamailio to use it as part of IRIS project:
With the inevitable phaseout of ISDN lines in the next years, SIP has been more and more adopted in the broadcasting industry, allowing open source RTC software to enter easier into this market.
Wishing all the best to IRIS project and looking forward to more usage of Kamailio beyond IP telephony.
Thanks for flying Kamailio!
