----------------------------------------

Hi - yes, and that patch has the obvious advantage of requesting a key frame on the first received video frame.

> In a video call Linphone and PJSIP clients use SIP INFO to request a video key frame. These packets appear to be silently dropped by the Asterisk PJSIP channel. Asterisk chan_sip appears to send a 200 OK response. In both cases the pkts are never forwarded on and video quality can be poor as a result.
