    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.
