Thanks for your response. I didn't precised than i'm developping a proxy server.
A proxy server needs to respond to the cancel with a ok and forward a clone of the cancel request to all the callees. But i can't retrieve the callees because the cancel does not match any server transaction and i can't create a new one. I want to know if a cancel request must be matched to a server transaction or not. Thanks.
