A Session Border Controller (SBC) is a network function which secures voice over IP (VoIP) infrastructures while providing inter-working between incompatible signaling messages and media flows (sessions) from end devices or application servers.
Use SBC for VoIP threats
A Session Border Controller (SBC) will allow you to connect your remote workers and SIP trunk(s) securely to your phone system without compromising security, automatically detecting VoIP threats and taking action.
Additionally, SBCs can automatically translate codecs and audio with built-in interoperability and transcoding capabilities.
Detect malicious VoIP traffic
SBCs sit between your internet connection and corporate network and analyzes all the VoIP traffic that passes through.
It is designed with security features to detect malicious VoIP traffic and automatically take action to save your network.
