Example 2
The Oracle® Enterprise Session Border Controller might determine from a local policy lookup that several routes are applicable for forwarding a SIP message. The Oracle® Enterprise Session Border Controller will try each route in turn, but the SIP response recursion disable feature can be implemented to stop the route recursion when a configured responses message is received by the Oracle® Enterprise Session Border Controller. See the following example:

There are a few conditions on the parameter used to configure response recursion:
- SIP Route Recursion is configurable for either the SIP interface or session agent.
- 401 and 407 are preconfigured for all configured SIP interfaces. They are not configured for session agents.
- The format is a comma-separated list of response codes or response code ranges: 404, 484-486.
- Only response codes that fall within the 3xx, 4xx, and 5xx range may be specified.
