The Sonus SBC 1000 is purpose-built for midsize enterprises and branch offices, delivering robust security while offering unparalleled interoperability between disparate networks. The SBC 1000 also features built-in survivability for Microsoft and BroadSoft, so calls go through even if the wide area network (WAN) goes down. 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 on-site technician. Smaller businesses and branch offices can now enjoy the same industry-leading SBC technology used by large service providers in an appliance designed specifically for their unique needs.
