New module - get UA config via presence service

Kamailio SIP Server has now a new module named presence_profile - the module extends presence server implementation with ability of handling ua-profile event. When an user agent subscribes to ua-profile event for its own AoR, it will retrieve profile data document via body of NOTIFY request.

The profile data document format is usually specific per user agent, such documents have to be built and added to presentity table by the admin or a third party application.

New module – execute control commands over HTTP

The development repository of Kamailio SIP Server includes a new module, named xhttp_rpc, that allows execution of RPC control commands via HTTP(S). Just for example, you can list active TCP connections, dump user location records from memory, reload the records for LCR or load balancing rules.

The module reuse existing xhttp module, therefore it has no external library dependencies and the processing rate matches the performances of processing SIP requests.
