Redirect—LRQ Management Sample 3
In this call flow, the SIP server issues a 2xx Successful message that is not supposed to be sent (because a 3xx, 4xx, or 5xx message should be sent in response to the Oracle® Enterprise Session Border Controller ’s INVITE). The Oracle® Enterprise Session Border Controller sends a BYE message to the SIP Redirect Server, but it tries to initiate the session again, this time successfully. The final sample call flow shown rarely occurs.
