[Asterisk-Users] Problem when i make a DATA CALL

[Dilson Freitas]

We have here a TandBerg "videoconferencing system"  connected in asterisk
with a Beronet card BN4S0 (4 BRI ports). I`m trying to make a videoconferece
(video + audio) with this Tandberg to another Tandberg using the ISDN
channels through the BN4S0 BRI Card. But, i'm only obtaining audio calls,
the video not appears. When i try to make a 64K calls (data calls), the call
does not complete.

I`m trying with asterisk branch and trunk. The problem appears with both
versions.

I think that the problem is in libpri with "User Information Layer
1", because when i try to make the call the follow "pri debug span 1"
appears:

********* When i make a speech call: (i have sucess here) ***********

-- Executing Dial("mISDN/1-u3", "Zap/g2d/0211130710535|20|Tt") in new stack

Someone has some idea? Thanks a lot.
