Session Border Controller (SBC)

A Session Border Controller (SBC) is a device used in telecommunications, particularly for managing voice over internet protocol (VoIP) calls. It acts like a gatekeeper for these calls, ensuring they are secure, high-quality, and compatible with different networks. SBCs help protect against unauthorized access, control call traffic, and enable smoother communication between different service providers. They are essential in modern communication systems, allowing users to connect seamlessly and safely, whether they're making a phone call, video conferencing, or streaming audio over the internet.
