When you take a moment to look over your logic above, you will see you are trying to explain the same thing with both entries. A timing of zero is to ignore line timing and generate your own. The channel bank would then use the line timing to sync itself. A timing of non zero is to pick up timing from the line in lessening priority as the numbers increase. You would want to set a timing of 1 if you are connecting the span to a PSTN provider or some hardware connected to the PSTN. You would set other non zero timings for other PSTN touching lines. Only put a zero in place if you already have timing or if you are sending to a non PSTN connected device. -- 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
