Subject: [asterisk-users] DAHDI hangup detection<br>
<br>
I am running Asterisk 1.6.1.6 and DAHDI/DAHDI tools 2.2.0.2 compiled<br>
from source on a Debian Lenny box, also running FreePBX 2.5.2. I also<br>
have an OpenVOX TDM400 card installed with an FXO port on port 1, and an<br>
FXS port on port 2. I have a POTS line installed and working on the FXO<br>
port.<br>
<br>
However I've encountered a weird problem that I can't seem to figure<br>
out. I have incoming POTS line calls set to ring a SIP extension (a<br>
cisco IP phone). It works, but here is the issue:<br>
<br>
- If an inbound call comes in on the POTS line and hangs up before the<br>
call hits voicemail or during the voicemail greeting, Asterisk does not<br>
appear to detect this condition.<br>
- As a result of this, a voicemail is being left with a dialtone and<br>
notifying me<br>
<br>
As a workaround, I have set busy detection in chan_dahdi.conf and set 12<br>
seconds for a minimum voicemail message in voicemail.conf, but I must be<br>
missing something or something is potentially broke. While this<br>
workaround works, I don't suspect this behavior I am experiencing is<br>
normal and I am having a hard time putting a finger on it.<br>
<br>
Thanks for any replies.<br>
<br>
Stephen<br>
