When we had a MCI ct1, they couldn't send us proper supervised hangup on a loopstart encoded DS0. They claimed it to be a problem with the software on their switch. Their solution was to switch to groundstart. Our end solution was to drop them and switch to Telcove(formerly Adelphia) and get a PRI where we controlled the signaling with asterisk. -- 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
