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.

Hello,

Looking at the Q.931 spec (3.1.2), it looks like our PBX would be correct
to stop sending digits when it receives a CALL PROCEEDING message, since at
that point Asterisk has indicated that it won't accept further
establishment information.
