It depends on what we mean by "ignore". It can ignore the SDP CONTENT, but it cannot ignore the fact that it now receives the SDP answer in a reliable response, that terminates the offer/answer transaction. I know it sounds messy, and that's why I wouldn't like to say anything else than the SDP in a unrelaible resposne is a copy of the SDP answer - nothing more. It's a copy of the answer, the UAC can assume it is identical to the answer, but it is NOT the answer :) As soon as we start talking about sending SDP answer in unreliable responses people may think that it finishes the offer/answer transaction, and then we need lots of text saying that is not the case... Confuses it does.
