FYI, I was looking at the IANA registry for SDP parameters ( http://www.iana.org/assignments/sdp-parameters/sdp-parameters.xhtml) and noticed that there was a registration for addrtype E164 linked to this CS draft. There's a problem that there's already an addrtype E164 in RFC3108. This earlier usage of E164 should have been registered with IANA but seems to have been missed. To complicate things the format of the RFC3108 E164 addrtype is different to the one in the CS draft. I've already raised this with IANA but I thought it would be worth mentioning in MMUSIC.
