But anyway, if the INVITE has been replied with a 200 it makes no sense at all to send a CANCEL so the proxy shouldn't reply 200 to the CANCEL, but a 481.
Not exactly, sorry, the proxy should forward the CANCEL stateless:
16.10 CANCEL Processing [...] If a response context is not found, the element does not have any knowledge of the request to apply the CANCEL to. It MUST statelessly forward the CANCEL request (it may have statelessly forwarded the associated request previously).
