OpenSER is a Session Initiation Protocol (SIP) proxy server, call router, and user agent registration server used in Voice over Internet Protocol and instant messaging applications. OpenSER is free software and is licenced under the GNU General Public License.
OpenSER can be used in small systems, for example in embedded systems like DSL-router, but also for large installations with several millions of customers for Internet Service Providers.1 The software is mainly distributed as source code, but some vendors like Cisco also sell hardware that contains an embedded OpenSER.2
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. OpenSER is mostly written in the C programming language and runs primarily on Unix-like operating systems. New functionality can be embedded through its module interface.
On 28 July, 2008 the OpenSER project was renamed to Kamailio, because of trademark conflicts. Shortly after that, the project was divided and an addition effort, OpenSIPS, forked stemming from a conflict between the core-developers.34 Development and maintenance of the software is now conducted by two separate development teams, each of them with different priorities and agendas. In November 2008 the Kamailio developers announced to team up with the SIP Express Router developers to form the sip-router project.56
