Kamailio SIP Server v5.1.10 stable is out – a minor release including fixes in code and documentation since v5.1.9. The configuration file and database schema compatibility is preserved, which means you don’t have to change anything to update.

Important note: v5.1.10 is the last planned release in the 5.1 series, marking the end of official maintenance for branch 5.1. Consider to upgrade as soon as possible to 5.2.x or 5.3.x series to ensure you are running supported releases.

Kamailio® v5.1.10 is based on the latest source code of GIT branch 5.1 and it represents the latest stable version. We recommend those running previous 5.1.x or older versions to upgrade. There is no change that has to be done to configuration file or database structure comparing with the previous releases of the v5.1 branch.
