      An outgoing call may not get hung up if a pre-connect incoming ISDN call is disconnected.
      
      If the ISDN link a pre-connect incoming call is using fails or is reset,
      the outgoing leg may not hang up or be delayed in hanging up.  (Causes:
      PRI_CAUSE_NETWORK_OUT_OF_ORDER, PRI_CAUSE_DESTINATION_OUT_OF_ORDER, and
      PRI_CAUSE_NORMAL_TEMPORARY_FAILURE.)
      
      Just hang up the call if the incoming call leg hangs up before connecting
      for any reason.  It makes no sense to send a BUSY or CONGESTION control
      frame to the outgoing call leg under these circumstances.
