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 -- Making new call for cr 32776 -- Requested transfer capability: *0x00 - SPEECH*> Protocol Discriminator: Q.931 (8) len=35 > Call Ref: len= 2 (reference 8/0x8) (Originator) > Message type: SETUP (5) > [04 03 80 90 a3] > Bearer Capability (len= 5) [ Ext: 1 Q.931 Std: 0 Info transfercapability: Speech (0)> Ext: 1 Trans mode/rate: 64kbps, circuit-mode(16)> * Ext: 1 User information layer 1: A-Law (35)* *********** When i make a data call: (i don't have sucess here, it does not complete the call) ********** -- Executing Dial("mISDN/1-u4", "Zap/g2d/0211130710535|20|Tt") in new stack -- Making new call for cr 32777 -- Requested transfer capability: *0x08 - DIGITAL*> Protocol Discriminator: Q.931 (8) len=45 > Call Ref: len= 2 (reference 9/0x9) (Originator) > Message type: SETUP (5) > [04 02 88 90] > Bearer Capability (len= 4) [ Ext: 1 Q.931 Std: 0 Info transfercapability: Unrestricted digital information (8)> Ext: 1 Trans mode/rate: 64kbps, circuit-mode(16)> *Ext: 0 User information layer 1: Unknown(24)* Someone has some idea?
