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.
