Redirect-Action Set to Recurse-305-Only

The following occurs if you set the redirect-action parameter to recurse-305-only 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 a 305 REDIRECT response to the Oracle® Enterprise Session Border Controller with the same URI as the URI sent in the original request.
4. The Oracle® Enterprise Session Border Controller forwards the 305 REDIRECT response to X (UAC).
5. If 305 response received, X sends requests to Y directly. If other 3xx responses received, requests are sent to URI specified in the 3xx response (works the same as if redirect-action set to proxy).

   The following illustration shows an example of a dialog between X, Y, and the Oracle® Enterprise Session Border Controller during a redirect-action session set to recurse-305-only.
