Joachim,

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.

Subject: H.323 AnnexD & mandatory fax OpenLogicalChannel elements


Hi all,

>From H.323 AnnexD, D.7:
"The H.323 AnnexD gateway shall send both a voice
and a fax OpenLogicalChannel element in the setup
message".

Could anyone envolved in the development of AnnexD
please outline the facts behind the _mandatory_
voice _and_ fax OpenLogicalChannel elements?

Does this really mean that a H.323 gateway needs to
open (or, at least offer) a fax channel beside each
voice call if it intends to be also AnnexD compliant?
The gateway can decide on the type (voice, fax) of
the connection anyhow only _after_ the end-to-end
voice channels are connected.


Thanks in advance,
Regards
