[Asterisk-video] h324m video on Sangoma E1 problem

[Karim Morsli]

Guys,

I have been following the threads re:3G calls w/ Video with great interest,
as I have been wanting to experiment with that. I've seen the benefits of 3g
video calls whilst traveling internationally, but here in the US, I can not
do it just yet. Or am I wrong? Anyone in the US able to conduct 3G video
calls?

Thx,
Karim

Thanks, it almost works now. 
The h324m_loopback works perfectly but when i tried to call my softphone via
h324m_gw, i see video on my mobile but i dont see video from mobile on
softphone (Ekiga).
Wireshark shows incoming video RTPs as: PT=Unknown
Outgoing RTPs are: PT=ITU-T H.263
