[Asterisk-video] h264 with Polycom HDX series

[Loïc]

Hi,

I'm trying to use Asterisk 1.4.29 to connect two Polycom HDX in High  
Definition h264 format with SIP.
When I use h263 , no problem. However, when I try to use h264 I can not  
have the video streams. The communication is well established : I have a  
G711 audio stream but no video.

If I use a SIP h264 videophone with a Polycom HDX, the Polycom well  
receives the video stream but no video on the SIP videophone.

Any ideas what is the problem ?

sip.conf
