Thanks Steve, have done as you suggested and it works perfectly. Would this be considered a bug since the T or t directive in the dial plan probably should preclude native bridging if the end result is to prevent a transfer? _______________________________________________ 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
