Session Border Controllers (SBCs) provide security, interoperability, routing and other functions in a Session Initiation Protocol (SIP) network. However, not all SBCs are created equal, and not all SBC customers have the same criteria.
While most network vendors will tell you they have a plan for IP evolution, we put our plan into practice every day in some of the world's largest networks. At the heart of that evolution is the hybrid media gateway that started it all: the Sonus GSX series. Over 40% of all long distance IP-voice traffic passes through a Sonus GSX gateway—making it the world's most trusted media gateway.
The GSX 9000 high-density gateways support a flexible mix of TDM and IP ports for a seamless evolution from circuit-based to SIP-based networks. As network traffic evolves to all IP, the GSX 9000 gateway evolves with it through a simple upgrade to become the SBC 9000 Session Border Controller. In addition to TDM network support, Sonus provides SS7 network interconnect through the SGX 4000 Universal Signaling Gateway. Together, the GSX and SGX gateways deliver complete legacy network interconnect for a smooth transition to SIP technology.
