OpenSER Developer(s) The OpenSER Team Initial release June 14, 2005 Stable release 3.2.0 / October 18, 2011 Written in C Operating system Linux and other Unix-variants Type Voice over Internet Protocol License GNU GPL Website www.kamailio.org, www.opensips.org 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 routers, but also for large installations at Internet service providers with several million customers.[1] The software is primarily distributed as source code, but some vendors like Cisco also sell hardware that contains an embedded version of 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 added 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 forked into an addition effort, OpenSIPS, stemming from a conflict between the developers.[3][4] 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.[5][6]
