<BR>
I found this same issue with all H.264 devices in the 1.4.x. The problem is that the main branch (correct term?) of Asterisk isn’t supporting FMTP for the RTP payload in H.264. This is used to declare the H.264 profiles/levels and other options in the call SDP, and without it, the SIP device hears strange voices about H.264, is confused, and does nothing ;-)<BR>
<BR>
Follow this old thread (<a href="http://www.mail-archive.com/asterisk-video@lists.digium.com/msg00101.html),">http://www.mail-archive.com/asterisk-video@lists.digium.com/msg00101.html),</a> it’s worked well for me using Polycom PVX and other SIP H.264 devices.<BR>
<BR>
Regards,<BR>
