H264 / vp8 over IAX2 with PJSIP

Asterisk Asterisk Support
1

Hello,
I’ve successfully configured an Asterisk server for video calls with h264 or vp8.
Calls between users in one Asterisk gets video.
Calls that are routed over IAX2 to users in another Asterisk (with the same configuration) do not get video.

I notice that if codecpriority=disabled in iax2.conf, the video is negotiated but no video stream seems to be passing through.

I’ve reached roads-end on this and would like some ideas on what I’m missing.

Video support in IAX2 is old, and very very basic. It does not support exchanging additional video negotiation details for example.

Thank you for the explanation. That should mean my effort to rewrite our software to use PJSIP instead of IAX2 was the right way to go.
