Thats true of telcos in the states as well. I wouldn't doubt it if many telcos behaved that way. I believe one of our previous providers had mentioned that if they encountered too many errors in a certain time frame the switch automatically disabled the line. While I took it as a warning to not muck with the config too often or much, but I bet it is to force someone to take notice of something is failing. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ 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
