About SIP Interfaces

The SIP interface defines the transport addresses (IP address and port) upon which the Oracle® Enterprise Session Border Controller receives and sends SIP messages. You can define a SIP interface for each network or realm to which the Oracle® Enterprise Session Border Controller is connected. SIP interfaces support both UDP and TCP transport, as well as multiple SIP ports (transport addresses). The SIP interface’s SIP NAT function lets Hosted NAT Traversal (HNT) be used in any realm.
