Redirect-Action Set to Proxy

The following occurs if you set the redirect-action parameter to proxy on the Oracle® Enterprise Session Border Controller:

1. X (UAC) sends an INVITE to the Oracle® Enterprise Session Border Controller.
2. The Oracle® Enterprise Session Border Controller forwards the INVITE to Y (UAS).
3. Y sends the 3xx REDIRECT response to the Oracle® Enterprise Session Border Controller with a different URI in the message header.
4. The Oracle® Enterprise Session Border Controller forwards the 3xx REDIRECT response to the previous hop. X receives the 3xx REDIRECT response from the previous hop.
5. X redirects all subsequent requests to the URI in the message header received from Y.

   The following illustration shows an example of a dialog between X, Y, Z, and the Oracle® Enterprise Session Border Controller during a redirect-action session set to proxy.
