Dear Mme Lapierre, I find it a little confusing that your email says that standards makers will present what the signalling of VoIP will look like, and that your agenda refers to the session as an H.323/IP workshop, yet none of the scheduled talks seem to talk about H.323. Rather there seems to be a focus on the gateway control protocols (SGCP and IPDC) which as you know, are being pushed by some parties as replacements for H.323. Can you clear up my confusion?

Good evening,

please find attached an invitation to a workshop on VoIP where key VoIP experts will be present. Standards makers will present what the signalling of VoIP will look like, and its impact on the network architecture. IP / VoIP manufacturers will be there. Operators will be discussing how and when they see VoIP in their networks. I will be happy to chair this session.

The workshop is sponsored by the TINA consortium, so that the entry is free. Nevertheless, we need to know the number of persons who will attend to determine the room size, so be kind enough to register if you or a representant of your company are coming.
