Summary:                    Agent shows "(In use)" and will not receive queue
calls while agent is logged in waiting for queue calls (1.4.22)
Description: 
I have a queue with approximately 50 total agents, about 20 of which will
be logged in at any given time.  Seemingly randomly (if there's a pattern,
I haven't discovered it), sometimes after an agent completes an inbound
call the agent status (as displayed in "show queue x") changes to "(In
use)" and the agent never again receives a call until that agent logs off
and logs back into the queue.  

This will happen about 15-20 times every day with seemingly random agents
at seemingly random times.  It happens when there's only one agent logged
in or when we have a full 20 logged in.  I can't identify a pattern that
would cause this problem.

This causes a huge problem, because we are missing calls and breaking our
SLA agreements with clients even though we have enough capacity and people
sitting waiting for calls.  As a workaround we are trying to get each agent
to log off the queue and log back on the queue after each call, but they
often forget.

---------------------------------------------------------------------- 
After doing several tests, here's some data I've come up with.

1. With my current setup, an Agent can take exactly one call. After that,
he will never get a "beep" from the queue. Using "queue show" I see that
his status is "not in use."

2. I see the Agent's status permanently change to "in use" if the phone he
is using re-registers with Asterisk.

Have you also seen the behavior that an agent can take exactly one call
before not being able to accept any more?
