Careful Dale. It is required if the early answer was *unreliable*. If the early answer was in a *reliable* 18x, then its repeat in 200 is *optional*. I agree in that case that it is a bad idea to include it, but it is allowed. Oops, my mistake. I assume that the obligation of the UAS to put the SDP in the 200 is removed when it receives a PRACK of a provisional response that had SDP? That is, if it *doesn't* get PRACKs that it expects, it must put the SDP in the 200.
