asterisk users - Mar 2006 - What do the Queue timeouts really mean?

Rather than continue to go in circles with queues, I'll ask upfront.

What exactly does the timeout option in queues.conf specify? The docs contradict
themselves on the meaning. What exactly does the timeout option passed to
Queue()? Docs are flaky there also.

I have a BIZARRE situation where I'm transferring a call from one box to
another with IAX where the call is handled by Queue(). When I set timeout= in
queues conf, the queue terminates at this timeout period and sends CHANUNAVAIL
back to the calling server, eventhough the call was already accepted, and was
picked up by Queue().

When I set timeout to something, each agent rings for 15s. Where is that coming
from? I don't have it in Queue(), in the Dial callback, or in queues.conf.

This is REALLY confusing.
