No, Ricardo, that is not the correct inference. First, if the ACK is an
end-to-end ACK (as for a 200 OK), it is generated by the sending
endpoint, and the SER proxy is not responsible for constructing it.
Secondly, there are various reasons why an ACK may have a request line
not equal to the Contact URI established as the dialog target, having to
do with backward compatibility with RFC 2543.
