Cancel is hop by hop. It is not forwarded. So, in theory, the Max-Forwards can be the default value (70) when the statefull proxy sends a new CANCEL.
See section 9 of RFC 3261. A stateful proxy responds to a CANCEL, rather than simply forwarding a response it would receive from a downstream element. For that reason, CANCEL is referred to as a "hop-by-hop" request, since it is responded to at each stateful proxy hop.

I am testing the proxy functionality of a statefull sip stack. Is it mandatory that the Max-Forwards header be decremented in CANCEL request when it is forwarded from one hop to an other.
