Kamailio v1.4.0 Released

KAMAILIO v1.4.0 is released

August 7, 2008

Kamailio is the new name of the SIP server known so far as OpenSER. Due to trademark issues, the OpenSER project had to change the name. Officially, the new name was announced on July 28, 2008.

Version 1.4.0 brings many new features since OpenSER v1.3.0 as well as improvements to existing components. An important share of effort was directed to code cleanup and stability. Moreover, new features in core and old modules were added while other 6 new modules were introduced.
