What is the difference between Cisco Unified Border Element and a conventional Session Border Controller?

Both CUBE and conventional SBCs offer robust SIP security features, including TLS, SRTP, and protection against denial-of-service attacks.

DTMF interworking, such as converting between RFC 2833 and SIP INFO, is a common feature provided by both CUBE and conventional SBCs.

Cisco Unified Border Element (CUBE) is deeply integrated into the Cisco Unified Communications ecosystem, allowing for advanced voice policy enforcement that leverages Cisco UCM routing and features. CUBE offers more specific and granular control over call routing, media flow, and policy applications within a Cisco-centric environment, often aligning directly with UCM call control policies.

Address hiding (topology hiding) is a standard security feature implemented by both CUBE and other SBCs to conceal internal network topology.
