I have a couple of Asterisk 13.4 servers with an IAX2 trunk between them:



[phone1] <--pjsip--> [server1] <--iax2 trunk--> [server2] <--pjsip--> [phone2]


With this setup, audio calls work fine, but video doesn't work:

I get a black window and if I remember correctly, I was getting white noise in one direction (not sure if the noise thing is asterisk's fault or the phone's).
I do see the video packets going through when I enable debugging on iax2, so this is strange.


I tested with linphone, pjsua, and a Grandstream gxv3240.



Video calls that don't go through the iax2 trunk work fine (eg: both phones in the same server).


If I change the trunk to use pjsip, video works fine, but then I have other problems that am still working on.

I'd rather keep using iax2 for my trunks for a while, so my question is:
Is anybody using video in this kind of setup?




Thanks.

I never got video to work over IAX2 trunks, specifically with the GXV- 32xx grandstreams. I've tested without success with asterisk 1.8 & 11.

I only managed video over SIP trunks and only at VGA resolution max over DSL links (~80-100ms latency), with barly acceptable frame rate.
