What is Session Border Controllers?

A Session Border Controller (SBC) is a network element that controls signaling and media streams involved in setting up, conducting, and tearing down calls in Voice over Internet Protocol (VoIP) or multimedia communication systems. They are deployed to manage security, interoperability, and quality of service (QoS) in VoIP networks. SBCs are commonly used at the edge of a network to protect it from attacks, ensure compatibility between different VoIP devices and protocols, and optimize media streams for efficient bandwidth usage.
