If the line is down (or incorrectly configured), you could be offhook without dialtone, though. I think the DSP suggestion might be the way to go. It would certainly be nice to have this functionality in asterisk, in general. I don't think there's currently (pun?) a way to detect if a POTS line is down. - Noah _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-gui mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-gui
