Summary:                    [patch] no audio with SIP call to ISDN PRI, if
neither Progress or Proceeding are received.
Description: 
After an upgrade from Asterisk SVN-r178446 to Asterisk 1.6.1-Branch.

Calling from SIP a phone to our ISDN PABX there is now no audio in either
direction.
Calling from the PABX into an Asterisk SIP phone audio is fine.

Audio on outbound call works fine on Asterisk 1.6.1.0-rc3 Tag,
but is broken on Asterisk 1.6.1.0-rc4 Tag.

The original patch (noted below) needs further work, to ensure audio path
is up when call is 'answered', may be earlier, when 'ringing' is received.

  No audio on calls from Asterisk to various ISDN devices until DTMF sent
by caller.
  
  Add missing clearing of the dialing flag when the ISDN call is
CONNECTED.
  (i.e. When libpri generates the event PRI_EVENT_ANSWER.)
