Redirect—LRQ Management Sample 2

The following diagram shows how the Oracle® Enterprise Session Border Controller handles the exchange when the SIP Redirect server declares either that there is an error or that there is no such user. These SIP messages come from either the 4xx Request Failure or 5xx Server Failure series. In the example below, the SIP Redirect server returns a 401 Unauthorized message, which the Oracle® Enterprise Session Border Controller interworks and communicates to the H.323 gatekeeper as an LRJ. Then the H.323 gatekeeper/gateway issues an ARJ to the H.323 endpoint.
