Hi,

I want to collect RTCP reports from snom devices via FS's event system.
Unfortunately it doesn't support it. Maybe because it is still a draft:

http://tools.ietf.org/html/draft-ietf-sipping-rtcp-summary-05

I wonder whether this feature is planed in near future.



Nevertheless I hacked sofia.c and sofia-presence.c to get it working
just for testing. Here is the "git diff":

It simply allows SIP PUBLISH events of type "vq-rtcpxr" and adds the sip
payload to the internal event body.
