H.323 Registration Proxy

The Oracle® Enterprise Session Border Controller provides a registration proxy feature that allows a gatekeeper to authenticate a registration before accepting it. This feature is key when two factors are present: authentication is required, and an RRQ from an endpoint includes a token and/or cryptographic token. If authentication for that endpoint is to work, the Oracle® Enterprise Session Border Controller must forward the registration requests received from the endpoint to the gatekeeper separately.When you do not use the H.323 registration proxy, the Oracle® Enterprise Session Border Controller combines all registrations received from H.323 endpoints into a single RRQ and sends it to the gatekeeper. Using the H.323 registration proxy, you can configure the Oracle® Enterprise Session Border Controller to use separate forwarding.

When registration requests are forwarded separately, each RRQ must have a unique CSA. This means that the Oracle® Enterprise Session Border Controller must perform a one-to-one translation of the CSA in the incoming RRQ to a distinct transport address. The translated address replaces the endpoint’s CSA in the outgoing RRQ. Then the Oracle® Enterprise Session Border Controller must listen for incoming calls that arrive at this translated transport address for the registered endpoint.
