Subject: [Megaco] Megaco: which spec to use?

Hello, 

May I ask some questions about which Megaco spec to hold on to...

For Megaco, Ietf has different documents:
  a.. Gateway Control Protocol Version 1: RFC 3015 (http://www.ietf.org/rfc/rfc3015.txt?number=3015) 
  b.. draft-ietf-megaco-3015corr-01.txt
  c.. draft-ietf-megaco-3015corr-02.txt (http://www.ietf.org/internet-drafts/draft-ietf-megaco-3015corr-02.txt)
As there is no RFC for version 2 yet, the only norm is version 1. Vendors who implemented specifcic corrections and amendements specified in the corrective documents are in fact not conform to the official Megaco spec, as "it is inappropriate to use Internet-Drafts as reference material or to cite them other than as work in progress." Is this interpretation correct?

Now, my second question: what about ITU-T's H.248 specifications? I understand that RFC 3015 corresponds to H.248. But what about H.248.1, H.248.2, etc. Are they official or just corrections and ideas for a new official spec yet to come?

Is any vendor relying on this spec, or does everybody take the RFC 3015?

Thanks in advance,
Pascal
