Hi! The RFC 3841, in the section 5 titled 'UAC Behavior' says,
"The Accept-Contact, Reject-Contact, and Request-Disposition header fields in an ACK for a non-2xx final response, or in a CANCEL request, MUST be equal to the values in the original request being acknowledged or cancelled. This is to ensure proper operation through stateless proxies." Why do we need to include these headers in the ACK or a CANCEL request?
