The HDLC problems were NOT solved or lessened. However, the telco (after insisting that they had throughly tested the lines) discovered that there was indeed a problem (unbalanced voltages in one of the pairs). When they fixed this problem, my "HDLC Abort" problem went away completely. The lesson I've learned: It's always the telco's fault :-) _______________________________________________ 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
