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. vineet -----Original Message----- From: joachim.fabini@SEA.ERICSSON.SE [mailto:joachim.fabini@SEA.ERICSSON.SE] Sent: Thursday, May 06, 1999 2:20 AM To: ITU-SG16@MAILBAG.INTEL.COM 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 --Joachim Fabini --------------------------------------- Joachim Fabini Ericsson Austria AG Pottendorfer Strasse 25-27 A-1121 Vienna, Austria voice: +43 1 81100-5127 fax: +43 1 81100-4686 email: Joachim.Fabini@ericsson.com ---------------------------------------
