A little background. I'm integrating asterisk as the voicemail service for an old Meridian/Norstar pbx which has an ATA-2 connected. The ATA-2 is used to connect an analog device (such as a voice modem) to the pbx. In the past we've used vgetty and a voice modem with varying degrees of success.
The problem is the ATA-2 does not provide disconnect supervision. When the outside caller hangs up, the line just goes silent. No busy signal. If the inside analog device hangs up the call, the ATA-2 then provides a dial tone. Right now, we've been using silence detection in voicemail to determine when the call ends. This works most of the time. On longer calls (say more than 5 minutes), sometimes the silence detection does not function and the call continues (with a bunch of recorded silence) until the maximum voicemail length limit is reached. Obviously, busy-detect is not going to work. The current silence threshold is set at the default 128. The FXO module is configured with Kewl Start signalling. Would I get better results (or any different results) if I switched to Loop Start? Any other ideas?
