The future is here for Session Border Controllers with Virtual TSBC, the full-featured, configurable subscription-based virtual session border controller!

By removing the physical layer from the SBC, it is much easier for customers to deploy the industry’s latest and most advanced technology. Just as importantly, it introduces a new pricing structure that eliminates CAPEX, and reduces OPEX to a point where carriers and service providers can deploy this SBC with licensing and full support, for less money than they’ve previously paid to support their existing SBCs. We think this new combination of performance and price point is a game-changer for the Session Border Controller marketplace. It will allow service providers to migrate to the latest and best technology without the CAPEX shock factor.

The new downloadable Virtual Tsbc, which is the industry’s first subscription-based virtual SBC from a brand name manufacturer of telecommunications equipment for carriers, supports up to 60,000 concurrent SIP sessions. It enables high performance SIP to SIP translation (B2BUA), header manipulation, extensive and flexible call routing, available transcoding, all while protecting the carrier’s network infrastructure from DoS and DDOS attacks.

The Virtual TSBC works on industry standard hardware and VM environments. It can also be deployed with external routing engines which will ease the implementation into existing carrier networks. The Subscription-based model eliminates CAPEX, and the Virtual Tsbc ensures revenue protection and peace-of-mind for carriers due to its reliability, security protection and full support.
