Chapter 4 in RFC3262 says:

"The UAC MAY acknowledge reliable provisional responses received after
the final response or MAY discard them."

Now, IF the UAC chooses to acknowledge reliable provisional responses after the final response is received, which route set should it use for the PRACK? The route set it used for the other PRACKs in the "early state", or the possible new route set is has for the "confirmed state"?
