What makes Cisco Unified Broder Element a better choice then a conventional Session border controller?

CUBE, as an integral part of Cisco's collaboration solution, offers superior voice policy management, allowing for deep integration with Cisco Unified Communications Manager (UCM) and other Cisco voice infrastructure components for sophisticated call routing, manipulation, and control. This enables more granular control over voice call handling compared to generic SBCs that might focus primarily on boundary control and basic security.

SIP security is a fundamental function of any SBC, including conventional ones, and is not a differentiating factor where CUBE is inherently 'better' in a general sense, as both provide essential security features.

DTMF interworking is a standard function for both CUBE and conventional SBCs, ensuring proper handling of dual-tone multi-frequency signals across different networks.

Address hiding (topology hiding) is a core security and privacy function of all SBCs, including CUBE, preventing internal network details from being exposed to external networks.
