There is MIKEY, but it is a bit overkill for most CPE vendors to
implement. It looks like draft-ietf-mmusic-sdescriptions-12.txt is getting
the most traction. I know of at least 4 CPE and 2 SBC that support it, I
know there is at least one KIKEY CPE, but I don't know of any major SBC
vendor that has implemented it.
