Global provider of SIP communications, Sonus Networks has introduced Sonus SBC SWe, the industry's first software-based Session Border Controller (SBC) designed to deliver unlimited scalability with the same features and functionality of the Sonus SBC 5000 Series on a virtualised platform. The Sonus SBC SWe allows customers to choose to deploy it on industry-standard servers or in virtualised environments and is scalable from as few as 25 to an unlimited number of sessions. Sonus will provide customers with a set of performance specifications for customers' host platforms, and customers can then rapidly exchange capacity, calls per second, features, transcoding and security capabilities with a license key as business demands change. The Sonus SBC SWe utilises the same codebase and management interfaces as existing Sonus hardware-based infrastructure and allows customers to deploy a fully featured SBC co-resident with other applications. For larger enterprise customers that might require a physical SBC in their data centres, the Sonus SBC SWe enables them to extend the same SBC capabilities to remote locations and branch offices without deploying additional hardware at each location.
