Building Kamailio in Docker

Thanks to Victor Seva from Sipwise, the Travis-CI jobs for building Kamailio were upgraded to useDocker containers.

A part of continuous integration process for Kamailio project, the builds are triggered by commits to master and stable branches, helping to detect compilation issues on different OS distributions, which typically happen due to different versions of libraries.

The bonus is that the same build system can be used locally by anyone, being it developer or VoIP engineer. Quite useful in cases when one wants to backport patches or develop its own extensions.

You can read the description of the build system as well as get the scripts from the source code of Kamailio, in the folder test/travis-ci. You can browse the content of the folder online at:

Enjoy!

Kamailio v4.3.4 Released

Kamailio SIP Server v4.3.4 stable is out – a minor release including fixes in code and documentation since v4.3.3. The configuration file and database schema compatibility is preserved.

Kamailio (former OpenSER) v4.3.4 is based on the latest version of GIT branch 4.3, therefore those running previous 4.3.x versions are advised to upgrade. There is no change that has to be done to configuration file or database structure comparing with older v4.3.x.

Kamailio Dispatcher Discovery Service with NodeJS and Etcd

An interesting resource for those relying on NodeJS for various needs and using Kamailio as load balancer in front of Asterisk or eventually other SIP systems (Freswitch, media servers, PSTN gateways, etc…):

• https://www.npmjs.com/package/kamailio-etcd-dispatcher

Practically, this tool can be run along side with Kamailio and each SIP system (e.g., Asterisk), usingEtcd as communication channel to publish what SIP systems are available. Based on this information, the tool instance next to Kamailio is generating the dispatcher.list and instructs Kamailio to reload that file.

Etcd is a highly-available key value store for shared configuration and service discovery developed as part of CoreOS project.
