PLANO, Texas, Oct. 21, 2024 /PRNewswire/ -- Ribbon Communications Inc. (Nasdaq: RBBN), a global provider of real time communications technology and IP optical networking solutions to many of the world's largest service providers, enterprises, and critical infrastructure operators to modernize and protect their networks, today announced that it has been selected as the technology provider for the US Department of Defense Information Services Agency (DISA) Soft Switch Backbone (SSBB) RFP awarded to ValidaTek, Inc. The mission of the SSBB is to provide a global, secure, and resilient mission critical voice communications infrastructure to all branches and agencies of the US Department of Defense.

Ribbon is delivering state of the art voice communication infrastructure components to help modernize and secure DISA's communications network, reducing cybersecurity vulnerabilities while lowering the cost of operations.

"The defense community is confronting an ever-escalating security threat environment, which legacy phone systems and communications equipment are ill-equipped to address," said Bill Grabner, Ribbon's Vice President, Federal Markets.
