I have a 2851 router with E1 interface connected to an ISDN network provider and a BRI interface connected to a Sony PCSA-B384S Video Conferencing unit.
I want the VC unit to be able to dial via the BRI circuits and "break out" through the E1 (ie. an ISDN call all the way through the router).
I have a layer 1 connection between the VC unit and the BRI, but the VC cannot establish a call.
I have attached a config file.
I know that q931 debugs would be useful and I will try to obtain these shortly, however, any help you could give based on the attached config would be much appreciated
