If I understand you correctly, the answer is yes: a UA can send SDP to its peer UA that contains a multicast address in the c= line, and the peer UA will send SDP to that address. That will have the desired effect if the network infrastructure correctly routes packets with that destination address. I've never heard of this being done. It's not clear to me why one would want to.
