The 15th Fosdem conference takes place in Brussels, Belgium, during Jan 31 – Feb 01. No open source telephony dev room this edition, allowing more time to discover other cool open source projects, many very useful to combine in deploying VoIP platforms, such as virtualisation, configuration management and monitoring.
Still a big group of Kamailio friends are around, among them: Alexandr Dubovikov, Giacomo Vacca, Adam Linford, Olle E. Johansson, Dan Bogos, Henning Westerholt, Daniel-Constantin Mierla. A dinner event is planned together with Emil Ivov and the Jitsi team.
A new module is available in the Kamailio development branch: dmq_usrloc
This module adds replication of user location records to multiple Kamailio nodes using the distributed message queue (dmq) module. It’s developed by Andrey Rybkin, one member of our expanding development team.
Replication of location records has been possible for a long time in Kamailio, using either actions in routing blocks such as t_replicate() or uac_req_send() or relying on the presence_reginfo + pua_reginfo modules. Also, using database replication layer or clusters was an option as well.
Integration with dmq offers more flexibility in adding and removing Kamailio nodes from the SIP platform and a simplified configuration file.
Kamailio SIP Server v4.2.2stable is out – a minor release including fixes in code and documentation since v4.2.0 – configuration file and database compatibility is preserved.
Kamailio (former OpenSER) v4.2.2 is based on the latest version of GIT branch 4.2, therefore those running previous 4.2.x versions are advised to upgrade. There is no change that has to be done to configuration file or database structure comparing with older v4.2.x.
