SIP SDP Address Correlation

SIP SDP address correlation ensures that when the Oracle® Enterprise Session Border Controller receives a request containing SDP, the L3 source address of the request is compared against the address in the c-line of the SDP. When the addresses match, the session proceeds as it normally would. If there is a mismatch, the call is rejected with the default 488 status code. You can also configure the code you want to use instead of 488.

This functionality works only with non-HNT users. The value c=0.0.0.0 is an exception and is always processed.
