CANCEL is not a stand alone transaction, it is tied to the INVITE transaction, thus if CANCEL is not getting 200ok, there is no failure route block executed for it. Furthermore, on a transaction stateful proxy, the CANCEL is hop by hop, the incoming one is absorbed and the outgoing one is generate by Kamailio. Local generated requests don't get failure route executed as well.
