[Asterisk-video] Trouble making outbound video calls

[Joost Kuif]

Hello people,

I am trying to make outbound videocalls with asterisk 1.4.22 and dahdi.
For triggering the call i use the asterisk spool directory.
I am at the point where asterisk is able to dial out to the mobile, and
the h324m_loopback is working ok. audio and video are working ok with
the loopback function. See details below.

When i change the h324m_loopback to the mp4play application and redial
again the mp4play function doesn't play audio or video.

One thing that gets my attention: why seems the transfercapability of
the channel in both cases SPEECH? the CLI logging says VIDEO is
requested for the transfercapability. Am i missing a patch? I did the
amr patch, the userlayer1 patch. The dahdi driver 2.0.0 and libpri 1.4.7
seems to already have the changes that last year had to be patched
manually.

Is it possible at all to initiate a video call and use mp4play through
the spool mechanism of asterisk? If not, what mechanism do you prefer if
you want to dial out automated (without dialing out initiated via a sip
client or whatsoever)? AMI interface maybe?


Regards and thanks for your help,

Joost Kuif
