Fosdem 2015

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.

Don’t forget about the next open source RTC event in Europe, the 3rd Kamailio World Conference, in Berlin, Germany, during May 27-29, 2015.

New Kamailio Module: dmq_usrloc

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.

The readme of the module is available at:

Kamailio 4.2 Tips: #12 - Execute RPC Commands In Config

Although part of a new module in Kamailio v4.2 - jsonrpc-s - this bit worth a special mention: one can now execute RPC commands from kamailio.cfg using the function jsonrpc_exec(...).

The main purpose of these commands was the execution from external applications, but sometimes comes handy to get access to them.

Next example shows how to execute dispatcher.reload:

jsonrpc_exec('{"jsonrpc": "2.0", "method": "dispatcher.reload", "id": 1}');

An useful use case for the above command can be execution in a rtimer route to perform period reload of dispatcher records.

Another example is to terminate an active dialog using h_entry and h_id.

jsonrpc_exec('{"jsonrpc":"2.0","method":"dlg.end_dlg","params":[4,8],"id":2}');

The RPC command has to be given as parameter to jsonrpc_exec() in JSONRPC 2.0 request format.

There are over one hundred RPC commands exported now by Kamailio and the number is increasing with each major release -- no doubt that many of them can be useful to trigger from kamailio.cfg.

Enjoy it!
