SIP B2BUA Peering

The Oracle® Enterprise Session Border Controller operates as a SIP B2BUA. It terminates SIP sessions and re-originates them as new sessions as they are routed through the Oracle® Enterprise Session Border Controller. For each session, it establishes NAPT translations and re-writes SDP to allow all session related media to be routed through the Oracle® Enterprise Session Border Controller. It generates new call IDs and modifies SIP headers to prevent any protected SIP addresses and route information from being transmitted to external peers. The Oracle® Enterprise Session Border Controller supports multiple SIP interfaces that are associated with a set of media ports, thus appearing as multiple virtual SIP gateways.
