I have experienced the same problem and would really like to see what the others have to say.
While testing, I put my router with a BRI-1B-S/T card behind a PBX with an NTI card and the problem vanished. This led me to believe that the problem has something to do with the telco. I *think* the telco switch may not be able to detect, in a timely fashion that your isdn line is active, because European ISDN switches normally deactivate layer 1 or layer 2 of an idle isdn line. Removing and re-inserting the cable sort of resets the layers 1 and 2. Has the same effect as typing "clear int brix/y" on the router.
