Summary:                    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".
