Hello, Can anyone help with an issue regarding the H264 profile level being passed through Asterisk? We have a video call like this:
Caller A -> Asterisk -> Called B Caller A's INVITE SDP offers "profile-level-id=42801f", and Called B replies a 200 OK containing "profile-level-id=42801e" in its SDP. Note that this ends with an 'e' rather than an 'f'. The problem is that Asterisk forwards the 200 OK to Caller A with "profile-level-id=42801f" in the SDP, so not what Called B sent. Caller A then starts transmitting video in a resolution that Called B can't handle, and the video is displayed as blank. My question is, since Asterisk doesn't do video transcoding, why doesn't it pass though Called B's "profile-level-id=42801e" unchanged? If it did then Caller A might use a resolution that Called B can handle. We are using Asterisk 11.25.3. Thanks in advance for any assistance. -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782
