This white paper presents real-world case studies describing how three organizations benefitted from implementing Cisco® Unified Border Element (CUBE), a session border controller (SBC) deployed on Cisco Integrated Services Routers (ISRs):
- An IT service provider with 100 employees migrated to Session Initiation Protocol (SIP) at its own pace by deploying CUBE alongside a Cisco time-division multiplexing (TDM) gateway on the same Cisco router
- A healthcare provider with 150 sites implemented CUBE, increasing availability and capacity, blocking unwanted calls and faxes according to voice policy, and lowering costs by 10-15 percent
- A global commodities trader deployed CUBE to interoperate with service providers around the world that implement SIP in subtly different ways, and to support high-definition videoconferencing
