A Session Border Controller (SBC) and a gateway serve distinct roles in a communication network. An SBC primarily manages and secures Voice over IP (VoIP) calls by controlling signaling and media streams, providing functions like call admission control, encryption, and protection against DoS attacks. In contrast, a gateway facilitates the conversion between different network types or protocols, such as between traditional Public Switched Telephone Networks (PSTN) and IP networks, enabling interoperability between disparate communication systems.
