The Ribbon Communications Session Border Controllers (SBCs) help the world’s leading enterprises reduce communications costs, enable Unified Communications (UC), and protect their networks against Internet Protocol (IP)-based attacks. Now small businesses and branch offices can enjoy the same industry-leading SBC technology in a right-sized appliance designed specifically for their networks. The SBC 1000 Session Border Controller is an advanced SBC that's independently verified for performance, delivering robust security features and interoperability between disparate networks. The SBC 1000 configurations are designed for ease of deployment and growth. Both session and port expansion can be remotely enabled via a simple license, eliminating the need for a truck-roll and an on-site technician. The Ribbon SBC 1000 also features a wide range of I/O and call capacities, as well as built-in survivability for Microsoft® Skype® for Business, Polycom®, BroadSoft™, and other SIP/TDM/FXx clients—so, calls go through even if the wide area network (WAN) goes down. The SBC 1000 is certified for direct routing with Microsoft Teams.
