B2BUA Hosted IP Services

The Oracle® Enterprise Session Border Controller acts as an outbound proxy for SIP endpoints and performs the operations required to allow UAs behind NATs to initiate and terminate SIP sessions (Hosted NAT Traversal).

The Oracle® Enterprise Session Border Controller caches registration requests from SIP endpoints and forwards them to the appropriate softswitch or registrar in its backbone network. All subsequent signaling between the endpoint and the backbone network is through the Oracle® Enterprise Session Border Controller. Also, all calling features such as caller ID, call waiting, three-way calling, and call transfer are all supported transparently through the Oracle® Enterprise Session Border Controller.
