SBC
SBC, or Session Border Controller, is a device or software that manages and secures communication sessions, particularly in Voice over IP (VoIP) networks. It acts as a gatekeeper at the edge of a network, controlling signaling and media streams between different networks or devices. SBCs help prevent unauthorized access, ensure call quality, and facilitate interoperability between various systems. They also provide security features like encryption and firewall functions, protecting against threats such as toll fraud or eavesdropping. In essence, SBCs ensure safe, reliable, and seamless voice and video communication across different network environments.
