ACK messages are in the same INVITE transaction ?
No, e2e ACKs are a transaction in their own right.
However:
(a) They will have the same CSeq number as the INVITE to which they correspond;
(b) They are a bit "special" in that they gather no responses.
My SBC is asterisk, and does not insert Record-route headers. Is it a normal behaviour for an SBC ?
Only proxies add Record-Route headers. The job of the endpoints is to marshal them into Route headers in in-dialog requests.
