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:
