The Cloud Communications division of NTT has chosen Radisys as sole supplier of media server licenses for Business Continuity Cloud Communications offering

HILLSBORO, OR, U.S. – April 22, 2021Radisys® Corporation, a global leader of open telecom solutions, today announced that the Cloud Communications division of NTT, an international technology services company, has chosen Radisys’ Engage Media Server to enable the migration of its legacy PSTN (Public Switched Telephone Network) conferencing solution to cloud-based communications platform. Radisys’ Engage Media Server delivers reliability and high performance for virtualized media processing as well as an innovative license migration solution that enables network-wide operations in the cloud.   


  • The COVID-19 pandemic has led service providers to rethink how they deliver voice and conferencing services to an increasingly remote work force and support changing usage patterns. At the same time, service providers are accelerating their migration to cloud-based communications services to better support business continuity and dynamic movement of capacity around the network.
  • To support these trends, NTT is migrating its legacy PSTN conferencing solution to a virtual environment. It is consolidating all licenses from multiple vendors for its legacy system and is now working with Radisys as the sole supplier for its Business Continuity Cloud Communications offering which delivers real-time voice and video communications. Radisys’ virtual Engage Media Server meets NTT requirements for license flexibility, performance and reliability.
  • By consolidating all media processing licenses with Radisys in a cloud environment, NTT will reduce the number of legacy licenses that need to be supported, while increasing the utilization of licenses in the network by 30 percent. NTT will be able to dynamically move capacity around the globe to where and when it’s needed.
  • Radisys’ Engage Media Server provides a range of media capabilities that streamline and enhance digital customer experiences. It provides services such as high-value voice and video features and enables NTT to leverage the cloud to offer reduced costs and access to users worldwide. The cloud-based Engage Media Server delivers:
    • Scalable HD voice and video communication services such as WebRTC, Keyword Detection and Speech to Text. 
    • Architecture flexibility as an integrated Media Server or as a decomposed Media Resource Function.
    • Consolidation of media processing under one, service agnostic platform. 

Chief Technology Officer for NTT Ltd.’s Cloud Communications, Jean Turgeon said, “Business continuity is critical during these uncertain times as we deliver essential conferencing and collaboration tools that allow to people to work and learn remotely from home. Radisys’ Engage solution has been a part of our legacy network, delivering the performance and reliability our customers demand. As we make the jump to the cloud, we are pleased to consolidate all of our licenses under Radisys’ Engage Media Server. It offers a diverse selection of real-time HD audio and video services and its support for future functionalities keeps the door open for continued innovation that allows us to serve our customer base as efficiently as possible.”
