Techopedia Explains Session Border Controller

A SBC manages data session communication between two entities and is associated with the following voice call streams:

One or more management signaling exchanges

Early SBC versions used a peer-to-peer (P2P) system for network border management. This functionality was gradually expanded to manage major service provider and backbone network deployments for residential and enterprise clients.
