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 Martin Euchner. ----------------------------------------------------------------------- | Dipl.-Inf.
