  Dialplan starts execution before the channel setup is complete.
  
  *  Issue 15655: For the case where dialing is complete for an incoming
  call, dahdi_new() was asked to start the PBX and then the code set more
  channel variables.  If the dialplan hungup before these channel variables
  got set, asterisk would likely crash.
  *  Fixed potential for overlap incoming call to erroneously set channel
  variables as global dialplan variables if the ast_channel structure failed
  to get allocated.
  *  Added missing set of CALLINGSUBADDR in the dialing is complete case.
