Kamailio SIP Server v4.3.7 stable is out – a minor release including fixes in code and documentation since v4.3.6. The configuration file and database schema compatibility is preserved.

Kamailio v4.3.7 is based on the latest version of GIT branch 4.3, therefore those running previous 4.3.x versions are advised to upgrade. There is no change that has to be done to configuration file or database structure comparing with older v4.3.x.

Important Note: v4.3.7 is the last official release from branch 4.3. Therefore it is strongly advised to consider upgrading to v4.4.x or 5.0.x as soon as possible to benefit of proper source code maintenance.
