For a CANCEL, the answer is 200 meaning that partysip has send a CANCEL
to the next hop and NOT meaning that the proxy will have a real answer
for the INVITE. The 487 (for the INVITE only) is trigerred by the new
CANCEL and after being received, will be forwarded by partysip as any
other response is forwarded.

Here is a link to a draft explaining the expected call flow:

http://www.ietf.org/internet-drafts/draft-ietf-sipping-basic-call-flows-01.txt

Here is the insteresting section:
