Hi I'd like to deploy an environment as follows:

a telephony gateway, which converts PSTN phone calls to H.323 calls. a gatekeeper, which is responsible for admission control and address translation, etc. If a user wants to use the gateway, he must pass the authentication, such as an valid ID/password.

My problem is: is it possbile for the gatekeeper to do the authentication with RAS channel or other H.323 messages?

It seems that admission control by the gatekeeper is for an H.323 endpoint, not for a 'user' of that endpoint. So in the above gateway environment, the gateway is admitted to the H.323 network, while the user might use a wrong ID/password to be rejected to use the gateway. Therefore it's not appropriate for the gatekeeper to do the authentication job. Am I right?

Thanks a lot.
