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.

queue show does show ringing...but here's the really interesting
information, why are there 2 callers shown, and only 1 phone ringing! This
happens with any strategy other than "ringall"

    -- Executing [s at macro-trunkdial:2] Queue("SIP/jeff-08210380",
"satellitebox1|r|||10") in new stack
satellitebox has 2 calls (max unlimited) in 'leastrecent' strategy (0s
holdtime), W:0, C:0, A:1, SL:0.0% within 0s
   Members:
      IAX2/000B3C01789D (Not in use) has taken no calls yet
      IAX2/000B3C02275D (Not in use) has taken no calls yet
      IAX2/000B3C022762 (Not in use) has taken no calls yet
      IAX2/000B3C022772 (Not in use) has taken no calls yet
      IAX2/000B3C02275C (Not in use) has taken no calls yet
      IAX2/000B3C02276C (Not in use) has taken no calls yet
      IAX2/000B3C02276F (Not in use) has taken no calls yet
      IAX2/000B3C016F39 (Ringing) has taken no calls yet
   Callers:
      1. Zap/8-1 (wait: 0:04, prio: 0)
      2. SIP/jeff-08210380 (wait: 0:02, prio: 0)
