Summary:                    [patch] [regression] Overlap dialing to PSTN failing
after https://issues.asterisk.org/view.php?id=16789
Description: 
In the UK, local and national calls can be variable length. In Asterisk
1.4.26.2 (and previously) the following dialplan (extract) works:

;National Calls
exten => _0[127]XXXXXXXX!,1,Dial(${GLOBAL(TRUNK)}/${EXTEN})
exten => _0[127]XXXXXXXX!,2,Hangup

In Asterisk 1.4.30, after the 10th digit has been received the call goes
to CALL PROCEEDING. No further digits are then received and forwarded to
the PSTN. It appears the ability to do "pass-through" overlap dialling
doesn't work anymore.

---------------------------------------------------------------------- 
The recovery was a restart of Asterisk.
I think we've tripped over this bug because of the dialplan problem. The
call was very short, and was just the inband message from the PSTN saying
number unobtainable (because last dialled digit was never sent). So, the
user just hung up.

Does the inband error message count as a call? If it doesn't, would the
call release properly after user DISCONNECT? It seems the q931 code checks
to see if the call is active first before sending RELEASE.

I'll do some more debugging and raise another bug.
