Would the channel-bank route affect this?
Another thing to find out is whether there are loading coils on the circuit. That can cause all kinds of strange problems if you're not using a purely electromechanical analogue phone. Did you test these circuits using a regular fax machine plugged directly into the circuit? Can you test with a good old-fashioned 56K modem; are you able to connect at a minimum of 28.8K? The fact is that line impairments can be quite expensive for telcos to fix. Right or wrong, it is a part of the reason why they'll attempt to convince you to give up on getting the problem solved. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
