Kamailio v3.0.0-RC1

Kamailio v3.0.0-RC1 is out - first release candidate for a new major version ...

The tarball with sources of Kamailio 3.0.0 RC1 is available at:

Target of release candidate is to ease the usage and testing. It is a version with a huge set of new features and enhancements, the first one using the SIP Router core framework, thefore we focus on heavy testing.

There is also now a tutorial to guide the installation of Kamailio 3.0 branch from GIT repository:

Two wiki pages were created to collect what is new in Kamailio 3.0 and how to migrate to this version:

Both documents still need a lot of care since many new features are missing or are not detailed, and definitely update guidelines do not cover all changes. Anyone can contribute and that is very much appreciated.

As we keep hunting and fixing issues, improve documentation, I hope to get to full release Kamailio 3.0.0 very soon. Enjoy RC1 meanwhile and report any issue you find to sr-dev at

Install Kamailio 3.0.0 from GIT

Just published a new a tutorial to guide the installation of Kamailio 3.0.0 from GIT repository:

This is a wiki page, open for improvements to everybody.

Now it is the time of release candidate, with full 3.0.0 to be out soon, but the tutorial is going to be valid for all releases numbered 3.0.x

Roadmap to Kamailio 3.0.0

I announced the plan to release Kamailio 3.0.0 next Wednesday or day after (October 28 or 29). With some delays, testing is going fine in my side, still some bits to be done, here is what I collected:
- taking in consideration $du updates in branch route
- import fixes from sr_3.0 branch
- complete core statistics and handling of drop reply

I believe is feasible, in the worse case we can package it at respective date and allow a bit more time for testing, but we unfreeze code and can go for new development. I encourage people to start writing migration documents.
