The Sonus SBC 2000 is an advanced SBC designed to help medium-sized enterprise networks safely and cost-effectively embrace the new world of SIP-based communications, such as Voice over IP (VoIP). The SBC 2000 delivers all of the features you would expect from the Sonus family of SBCs, including robust security, high availability and proven interoperability with leading business solutions like Microsoft Lync Server. The Sonus SBC 2000 also allows calls to go through even when the wide area network (WAN) goes down, with built-in survivability for Microsoft and BroadSoft. The SBC 2000 configurations are designed for ease of deployment and growth. Session and T1/E1 port expansion is remotely enabled via a simple license, minimizing the need for a truck roll and on-site technician.
