I don't think the zhones support external notification of alarm other than the LEDs. The CACs do for sure, and therefore it is a good bet the Adtran stuff does as well. I know on my CAC hardware there is an external plug to tie into to put any number of monitors on to detect when it has had a problem. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
