[asterisk-users] Video through IAX2 trunks

[Alan]

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.
