Session Border Controller (SBC) VoIP is a key component in modern IP-based voice communication systems. It operates at the edge of the network and manages SIP sessions to ensure secure, stable, and high-quality voice communication between internal systems and external VoIP connections.
What Does an SBC Do?
An SBC controls how voice sessions are established, monitored, and terminated. It acts as a gatekeeper for SIP traffic, ensuring that voice calls are handled efficiently while protecting the network from external threats.Key Advantages of SBC VoIP
