 +===== Overview =====
 +
 +**SIP Express Router** (aka **SER**) is the initial name of the project that emerged into Kamailio starting with 2008. It is a high-performance, configurable, free Session Initiation Protocol (SIP) server licensed under the open-source GNU license, offering a large set of features. Started in 2001, before the publishing of RFC3261 (SIP v2.0) in summer of 2002, Kamailio-SER pioneered the development of many SIP extensions and pushed further the real-time communications over IP.
 +
 +Initial project web site was:
 +  * http://iptel.org/ser
 +
 +Used over the time:
 +  * http://sip-router.org
 +
 +Now the web site is:
 +  * http://www.kamailio.org
 +
 +It is the oldest and most robust open source SIP server, routing **billions of VoIP minutes every month world wide**, being used from Telcos and Carriers to ITSP and SOHO  environments. If you haven't heard of it so far, it is very likely because your VoIP provider routes the calls fast and reliable with SER-based SIP servers, so you don't need to build your own system.
 +
 +First source code commit of SER-Kamailio was done **15 years ago**: **Sep 3, 2001**. According to GIT log, first three commits were:
 +
 +<code>
 +git log --pretty=format:"%h%x09%an%x09%ad%x09%s" --reverse | head -3

 +
 +That is ** 5479 days** of continuous development, with hundreds of contributors, estimated cost of development: **over 18 000 000 USD** (averaged 70000USD/year/developer and 261 person-years).
 +
 +===== Summary of Evolution =====
 +
 +  * **September 2001** - initial commit, SER was then developed for about one year internally at FhG FOKUS Institute, Berlin, Germany

 +  * **June 2005** - [[http://www.openser-project.org|OpenSER]] forked from SER, code hosted by Source Forge: http://sourceforge.net/projects/openser/
 +  * **July 2008** - OpenSER was renamed to [[http://www.kamailio.org|Kamailio]]
 +  * **November 2008** - SER and Kamailio teams decide to join development efforts and merge the source code trees of the two applications
 +    * development portal for both changed to: http://sip-router.org
 +  * **January 2010** - version 3.0.0 is released, from a source code tree containing both SER and Kamailio
 +  * **Septeber 2011** - the project celebrates 10 years of development
