Consider the following scenario:

UA sends peer UA BYE
Recipient of BYE sends OK and tears down the dialog.
OK gets lost so sender of UA re-sends BYE.
Now there's a dialog in Terminated State but no server transaction (it
has already been removed).

What is the most appropriate way for the receiver of the retransmitted
BYE to respond?

Should it respond with OK, CALL_OR_DIALOG_NOT_FOUND or SERVER_FAILURE
( due to the fact that the in-dialog BYE has been sent with a
previously seen cseq number) ?
