Note: Kamailio is the continuation of the former OpenSER project, name changed on July 28, 2008, due to trademark issues. First version under Kamailio name was 1.4.0. Older versions continued to use OpenSER name. Project site and SVN repository on SourceForge.net still use the old name OpenSER. Source code since release 3.0.0 (when the merge of source code trees of Kamailio and SER was completed) is hosted on GIT repository athttps://github.com/kamailio. Starting with version 4.0.0, SER has been absorbed in Kamailio flavour, which became the default distribution of the project.
