What are Session Border Controllers?
Session Border Controllers are in the network perimeter – or border – to control and secure a SIP (Session Internet Protocol) by admitting (or denying), then directing communications between multiple parties and devices.
Session border controllers control communication through an organization or service provider’s IP network. A session border controller also handles all the signaling and media functions required to make SIP work seamlessly.
Incorporating a session border controller as part of a Unified Communications plan avoids the oversight that can leave systems open to security risks and cost an organization time and money.
