Summary:                    Queue handling problems with IAX/possibly others
Description: 
I'll be glad to develop a fix for this, but I need some feedback as to
why/what/and general intentions.

I have 8 IAX members of a very basic rrmemory queue. When a call comes
into the queue, it will pick a single IAX channel to ring. 

The major problem is that until that IAX channel is answered, ALL
consecutive calls are routed to the same IAX channel. So, here's the
scenario.

> Inbound call -> app_queue -> ring IAX device
http://bugs.digium.com/view.php?id=1
> Inbound call -> app_queue -> ring IAX device
http://bugs.digium.com/view.php?id=1
> Inbound call -> app_queue -> ring IAX device
http://bugs.digium.com/view.php?id=1
IAX device http://bugs.digium.com/view.php?id=1 ANSWERED
> Inbound call -> app_queue -> ring IAX device
http://bugs.digium.com/view.php?id=2
> Inbound call -> app_queue -> ring IAX device
http://bugs.digium.com/view.php?id=2

and this should look like:

> Inbound call -> app_queue -> ring IAX device
http://bugs.digium.com/view.php?id=1
> Inbound call -> app_queue -> ring IAX device
http://bugs.digium.com/view.php?id=2
> Inbound call -> app_queue -> ring IAX device
http://bugs.digium.com/view.php?id=3
IAX device http://bugs.digium.com/view.php?id=1 ANSWERED
> Inbound call -> app_queue -> ring IAX device
http://bugs.digium.com/view.php?id=4
> Inbound call -> app_queue -> ring IAX device
http://bugs.digium.com/view.php?id=5

I would like to discuss why this is happening, or if it's intentional for
other channels such as SIP/ZAP/etc.

I have a patch for iax for counting currently active calls (minus
registrations/pokes/etc) which can help here too.
