Cisco Unified Border Element (CUBE)
Cisco Unified Border Element (CUBE) is an enterprise-class Session Border Controller (SBC) that facilitates secure, scalable, and flexible voice and video connectivity between enterprise networks and service provider SIP trunks. It performs four critical functions: session control, security, interworking, and demarcation. CUBE supports signaling interworking between SIP and H.323 protocols, media interworking for DTMF, fax, modem, and codec transcoding, as well as address and port translations for privacy and topology hiding. It also provides billing and call detail record (CDR) normalization, quality-of-service (QoS) and bandwidth management, and media services such as media forking and proxying. CUBE can be deployed on Cisco routers or as a virtualized solution on Cisco UCS servers, supporting centralized, distributed, or hybrid deployment models.
