This is incorrect. Asterisk *does* support far-end disconnect supervision, if you're using Kewlstart signaling. (Check to make sure you're using signalling=fxo_ks or signalling=fxs_ks in your channel driver configuration. And yes, you must spell signaling with two ls if you're using Asterisk 1.4 or earlier.) If you're simply using loop-start signaling, Asterisk won't be looking for the far-end disconnect signal. (For future reference, and to clarify Danny's point, Asterisk has no way of doing *answer* detection on FXO ports, as the telcos here in the US don't signal when the far end has answered. In other countries, the telcos will often do a polarity reversal to indicate far-end answer. That being said, we absolutely support *hangup* supervision.) -- Jared Smith Training Manager Digium, Inc. _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
