I'm trying to use Asterisk as a voice mail system and all is going well except for one issue. When the outside caller drops the connection Asterisk doesn't sense it. It keeps the line open for about 2 minutes before dropping it. The FXO is attached to a key system (hybrid PBX). There was a home-type digital answering machine previously on the same extension and it was able to sense disconnect without any problems. The interface is a non-Digium single port FXO card (modem) with R13 & R19 removed to mimic the Digium card. The software is the current release of Asterisk@home from ISO format (self booting CD that does an OS install and Asterisk compile automagically). My question is if Asterisk has settings to control disconnect sense, or do I have to look at the key system (hybrid PBX) that it's attached to. -James
Your line must provide disconnect supervision, which it sound like you say that it does, and you must configure that Zap trunk in asterisk for "kewl start" signaling (fxoks) which makes use of the disconnect supervision.

If not, there's not a damn thing you can do. -A.

If I dial the Asterisk machine as a local extension my PBX will send a busy signal when the line is dropped and Asterisk seems to detect it with busy + progress enabled, but when an outside caller is forwarded to the extension it doesn't get the busy-on-drop. There's a few settings I can try in the PBX (an Iwatsu ZTD).
