Session Border Controller

A Session Border Controller (SBC) is a networking device used in voice over IP (VoIP) and video communication. Its main role is to manage and secure connections between different networks, such as between a company's phone system and the internet. It helps ensure that calls are clear and reliable by handling things like call setup, maintaining quality, and protecting against security threats. Essentially, it acts like a gatekeeper, making sure that communications are efficient, secure, and end-user experiences are optimal.
