Hi, Martin:
I am responding to your general question:
I like to pint out that we will create "one common VLF/HLF protocol" that can be used by all applications (H.323, H.310, H.324, IMT-2000, and others) that like to support mobility related value-added services.
So, I do not think that we have agreed at all to extend H.225.0 Annex G for that purpose that will ONLY be specific to H.323 mobility.
If the properties of H.225.0 Annex G protocol are so good that we need to use all those for solving the mobility related VLF/HLF problems, we can still use those properties, if needed, for the "VLF/HLF protocol," but we will definitely NOT term as "H225.0 Annex G protocol." We will name it as a "new protocol" that can be used by all applications without restricting it ONLY to H.323.
The conclusion is that the proposal of extending the H.225.0 Annex G for the VLF/HLF services to make it specific ONLY for H.323 is HIGHLY controversial and will create many protocols (instead of one) for the same purpose within ITU. It will be disaster for both service provider and equipment manufacturer community.
Best regards, Radhika R. Roy AT&T

Hi Jaakko,
I'm not certain, whether I really understand the purpose of the EncryptionToken. If I look at Annex G v1, H.235 Clear and CryptoTokens are always present in each Annex G message; they are conveyed within AnnexGCommonInfo and thus are already part of each annex G message. Thus, I would say, that EncryptionToken is somewhat redundant and we do not need that this way.
The other question I have concerns AuthenticationRejection: Why do you reverse tunnel - that is, feed back - the tunneled message in the reject?
Finally a general question: Once there was a discussion that Annex G not only be used among Border elements as currently defined in the H.225 Annex Gv1 scope, but to extend its usage for mobility purposes. If this were true, then Annex G could be applied also between the GK-VLF/BE and between HLF/BE-AuF. What is the current status of that discussion?
Kind Regards

Mr. Fortinsky et al,
I have uploaded MD-110 containing a contribution on adding new, authentication related messages to the H.225 Annex G protocol, to the URL:
ftp://standard.pictel.com/avc-site/Incoming/Mobility-AHG/MD-110_AdditionOfMe ssagesToH225AnnexG.zip . I will send the contribution also to the two meetings in Geneva, but if you send comments really quickly (tomorrow) to me, I may be able to make some changes to the contribution, before distributing it.
