Vineet,

I do have the recommendation H.323AnnexD that is available from the ITU website. The sentence can be found on page 4 (D.7: Interactions with gateways and T.38/AnnexB devices), second paragraph.

Furthermore, section D.2 (Scope) says, that "An H.323 terminal that supports the procedures of this Annex shall interwork with T.38/AnnexB terminals". The interoperability with T.38 AnnexB terminals thus is mandatory.

My understanding of this is that AnnexD compliant H.323 gateways must use the fastStart procedures and open both, fax and voice channels when the receiving gateway is also a H.323 terminal supporting AnnexD.

I think you have a draft version of Annex D and not the decided version. I can't find the sentence you mentioned in your email in my copy of Annex D.
