Has someone else answered the call from the queue?
Has the pickup attempt failed?</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">app_queue places a call to perhaps more than 1 interface the caller hangs up in a race with a pickup of
the called interface from a 3 party [as best i can tell].
the result is a channel left orphaned that cannot be removed with no thread running on it this is happening frequently enough over various sites.
when the "pickup" is done the channel should be bridged or about to be bridged running autoservice on it till this happens is probably the correct thing to do WRT DTMF and the like and will allow the hangup frame to flush it.

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think waiting for a bridge that may never happen is not the way to go here. It sounds more like a problem in app_queue.c:wait_for_answer() not cleaning up correctly in a race between a queue member answering the call and the caller hanging up.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">i have only witnessed it in app_queue i suspect it may happen elsewhere ill look into app_queue further</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">seems like app_queue [and others likely] can leave a orphaned channel with no bridge and no thread running on it.
this is "ungood" here is a small patch that starts auto service waits for bridging and turns it off allowing the
hangup frame to get through and shut down the channel ... </pre>
