OpenSER is a SIP proxy server, call router, and user agent registration server
used in VoIP and instant messaging applications.
It provides all the functionality you may expect from a standard PBX.
The OpenSER-project was created on 14 June 2005 by two SIP Express Router (SER)
core-developers, Bogdan-Andrei Iancu and Daniel-Constantin Mierla, together
with the SER-contributor Elena-Ramona Modroiu. New functionality can be embedded through its module interface.
On 28 July, 2008 the OpenSER project was renamed to Kamailio, because of trademark conflicts.
Please note that OpenSER no longer exists.
It was divided into two projects, Kamailio and OpenSIPS.
The two projects are currently very similar, since they are built on the same code base.
