Summary:                    [patch] channels stuck in ringing state forever
Description: 
Scenario:
CALLER -> INVITE            ->  ASTERISK -> INVITE            -> CALLEE
CALLER <- SESSION PROGRESS  <-  ASTERISK <- SESSION PROGRESS  -> CALLEE
CALLER <- RINGING           <-  ASTERISK <- RINGING           -> CALLEE

After this short network out of order causes further packets lost and
channels are stuck in "show channels" forever.

Caller and callee gateways seem to hangup channel by retransmission
timeout, so they are clean and tidy.

You can reproduce this with attached sipp scenario being run on callee
side.
It simply doesn't response anything after Ringing - you'll see channels
stuck.

Attached patch.
I didn't find any info regarding this issue in RFC3261, so I invented my
own timeout of 1 minute. I guess this should be done configurable.
