As services such as Unified Communications, Conferencing, Collaboration, and Contact Centers, all continue their migration to cloud environments, it is vital that SBCs make that same transition. Ribbon's virtualization strategy continues on its heritage of ensuring secure, reliable, and scalable real-time communications.  With the virtualization of our SBC, we take the same extensive feature and functionality of our appliance-based SBCs, but now provide a software-only solution, the SBC Software Edition (SBC SWe).

With SBC SWe, service providers can be sure they will deliver secure real-time communications in multiple virtual and cloud environments without compromising scale, performance, or feature functionality.
