Sorry for disturbing you, but we have some problems with an installation with multiple (84) T1s from Quest. Now, our Problem is disconnected numbers are reported by sending in- band channel alert message and the B-Channel will have the tri tone and respective message but the line is never "picked up" and stays in ringing when dialling. So disconnected numbers are never detected as disconnected numbers. We tried this with digium and sangoma cards and the results are the same. Quest offered us a audible treatment of the line which made things even worse and would block the B-Channel for playing the message without asterisk being aware that the channel is still used. Otherwise we have a huge problem with congestion due to unavailable B- Channels when the number of connections in asterisk does not match the number of used channels / channels stay blocked after they have been hung up for several seconds, again this seems to be mostly the problems when b-channels carry audible alert messages. Thanks for any good suggestions! Frank Gorgas-Waller Explido Software USA Inc.
