 You're seeing this as a byproduct of the functionality at play here. 
app_queue has to establish a channel to ring the queue member and 
whether or not that queue members has answered, when the channel is torn 
down, you're going to get a hangup event.

 If you want to see the actual actions driven by app_queue you'll want 
to take a look at the AgentCalled, AgentConnect, AgentComplete manager 
events with the eventwhencalled behavior enabled for the queue in 
queues.conf. There's also a RINGNOANSWER queue action that is logged, 
but it doesn't presently throw a manager event when it happens. This 
might be a nice addition if you're looking to monitor for these events 
via the manager.
