Summary:                    [patch] Ghost calls with queues and spa942 and 922
Description: 
I am testing a simple static queue setup and i often get ghost calls (right
after the caller hangs up before anyone has answered) on my linksys phones
(but not on x-lite).

I also get these errors:
channel.c: ast_prod: Prodding channel ... failed
chan_sip.c: handle_response: Remote host can't match request CANCEL to
call ...

To reproduce it you have to call and be placed in que, noone answers, let
the "periodic-announce" start playing and then hangup.

I see a 2 weird things happen (imho):
- Right after caller hangs, Asterisk sends an INVITE and immediately a
CANCEL. Imho it shouldn't send any of them.
- Phone returns a "481 call does not exist".

  Prevent phantom calls to queue members.
  
  If a caller were to hang up while a periodic announcement or position
  were being said, the return value for those functions would incorrectly
  indicate that the caller was still in the queue. With these changes,
  the problem does not occur.
