A session border controller (SBC) is a dedicated hardware device or software application that governs the manner in which phone calls are initiated, conducted and terminated on a Voice over Internet Protocol (VoIP) network. An SBC provides security, interoperability, routing and other functions in a Session Initiation Protocol (SIP) network. It defines and monitors the quality of service (QoS) status for all sessions, ensuring that the callers can actually communicate with each other and that emergency calls are delivered correctly and prioritized above all other calls. An SBC can also serve as a firewall for session traffic, applying its own quality of service (QoS) rules and identifying specific incoming threats to the communications environment. Service provider class Session Border Controller (SBC) is designed to handle the high call volumes that the carrier will experience and provide full range of features required for carrier operations. Enterprises require different features than those provided by carrier session border controllers, including support for T1/PRI interfaces, small sites, local resiliency and interoperability certification with enterprise unified communications (UC) vendors.
