Session Border Controller

A session border controller (SBC) is a device regularly deployed in Voice over Internet Protocol (VoIP) networks to exert control over the signaling and usually also the media streams involved in setting up, conducting, and tearing down telephone calls or other interactive media communications. Early deployments of SBCs were focused on the borders between two service provider networks in a peering environment.
