automated call-in dispatch system where hundreds of people call in daily for
2-3 minutes each. The extension is set up to get their information, then
text-to-speech the dispatch information (via odbc). It then loops 5 times

though, I see calls via ‘core show channel dahdi/1-1’ that have a time of >

ODBC timing out, or TTS failing for some reason. When a channel gets in
this state, the call doesn’t seem to progress through the dialplan, they always
display the TTS line. Doing a ‘dahdi destroy channel 1-1’ doesn’t seem to
be effective – the only way I’ve been able to clear the calls is to do a ‘dahdi

Can you post the CLI output of a call that gets "hung"? I'd
like to see where it's hanging on. <br>
<br>
Also, as a work-around to attempt to solve the symptom and not the underlying
issue, you could maybe setup a cron job that runs once every ten minutes that
checks for stale calls using AMI, and then hangs up any calls up that are over
10 minutes long? Using the AMI Hangup command?<br>
