Part of the Cisco® Collaboration Edge Architecture, Cisco Unified Border Element (CUBE) is an enterprise-class Session Border Controller (SBC) solution that makes it possible to connect and interwork large, midsize, and small business unified communications networks with public and private IP communication services.

As a licensed feature set of Cisco IOS® XE Software, CUBE has a wide range of capabilities that may be used to secure, monitor, and maintain business-critical connections and to ensure compliance with industry standards. Collectively, CUBE features provide exceptional flexibility when architecting highly available enterprise communications networks that save money and offer richer voice and video collaboration experiences to users.

The vCUBE feature set is available for both the Cisco Cloud Services Router 1000V and Catalyst 8000V Edge Software products.
