<pre wrap="">Raj,
I am just confirming it happens here as well.
CentOS 5.7. Asterisk 1.8.15.1. DAHDI 2.6.1.
Digium, Inc. Wildcard TDM410 4-port analog card (rev 11)
Loadzone = us
The problem started manifesting itself after I switched to 1.8.x from
1.6.2.x
Typical scenario: a caller apparently hangs up, dial plan goes into
voice mail and records a 50 sec message with the CO tones. Then
something happens and the line finally gets hung up.

I feel this is a different problem:
<b>Problem 1</b>: Asterisk receives incoming call from PSTN. Caller hangs up.
Asterisk doesn't notice hangup and continues in the dialplan.
<b>Problem 2</b>: Asterisk receives incoming call from PSTN. Asterisk
eventually executes HangUp(). Caller does not get hung up.
Correct me if I'm wrong, but yours seems to be the first, whereas mine
is the second.
Solved the first one by loading the appropriate zones, loading the
Digium card driver with the correct opermode (which must be one of the
best-kept secrets on the Internet!) and enabling busydetect in Dahdi.
Stuck at the second one for now.

You are absolutely right. I am experiencing the <b>Problem 1</b>.
I never experienced your <b>Problem 2</b>.<br>
<br>
In my opinion my problem is related to the call supervision (reverse
polarity or voltage drop) being missed by Asterisk on occasion. I
do not use busydetect as I do not want to have false positives.<br>
<br>
Good luck with your Problem 2 struggle.<br>
