Voice stream multiplexing

I would like to know if the VoIP forum decided on a standard for voice stream multiplexing? Is there any proposals except the Hitachi proposal?

IETF AVT working group proposed at least 4 drafts to implement it, does the VoIP forum intend to corporate with IETF on that issue?
