The OpenSER project has been “renamed Kamailio“,  a hawaiian word (kama’ilio) which means talk or to converse.  If you go to the openser.org website, you’ll be redirected to kamailio.org. Starting with version 1.4 which is planned for release on August 7, 2008,  OpenSER will be called Kamailio.

So it’s about time to say goodbye to OpenSER and say hello to Kamailio, but let us also welsome OpenSIPS, a continuation of the OpenSER project.

Don’t be confused, Kamailio and OpenSIPS have taken the OpenSER code and pursue different goals and directions, this is called “forking” and it happens in an open-source project like OpenSER.

OpenSIPS (Open SIP Server) is a mature Open Source implementation of a SIP server. It is more than a SIP proxy/router as it includes application-level functionalities. As a SIP server, it is the core component of any SIP-based VoIP solution. OpenSIPS unifies voice, video, IM and presence services in a highly efficient way.

OpenSIPS has released OpenSIPS 1.4.0. with the following new functionalities:

• dialog profiling extension
• local route for internally generated requests
• dial plan / translation module
• general NAT traversal module (for non-invite signalling)
• peering and rate limit (traffic shaping) modules

OpenSIPS 1.4.0 has included the following enhancements:

• SRV load balancing (based on weights)
• nonce re-usage verification (safer authentication)
• bug fixing - code, specs and functionality bugs.
