Explanation

Cisco Unified Border Element (CUBE) is a Cisco IOS-based Session Border Controller (SBC) that acts as the demarcation point between enterprise and service provider VoIP networks. Its core features include: (A) Protocol Interworking - CUBE translates between different VoIP signaling protocols (e.g., H.323 to SIP), enabling interoperability between disparate systems. (E) Address Hiding - CUBE masks internal IP addressing schemes from external networks, protecting network topology from exposure. (F) Security - CUBE provides NAT traversal, TLS/SRTP encryption support, and acts as a security boundary to prevent toll fraud and unauthorized access. (G) Video Integration - CUBE supports video call flows, enabling unified video and voice communications across network boundaries. The distractors (B) Bandwidth Control, (C) Admission Request, and (D) Automated Alternate Routing are not primary CUBE feature categories. Bandwidth control and CAC (Call Admission Control) are functions more associated with CUCM or RSVP agents, and Automated Alternate Routing is a CUCM dial plan feature.
