The collaboration will deliver scalable, flexible, and future-ready voicemail technology.

Radisys Corporation has announced that Unisys has selected Radisys’ Engage Media Server to enhance its voicemail offerings for Tier 1 mobile network operators (MNOs).

Radisys’ Engage Media Server enables Unisys to further modernize its infrastructure related to voicemail offerings and align with its cloud and container strategy. One of the critical voicemail services the Radisys platform provides is the Media Resource Function (MRF), responsible for tasks such as media mixing, transcoding, and dual-tone multi-frequency (DTMF) signal detection. Unisys chose Radisys’ Engage Media Server for its ability to deliver performance in virtualized and cloud-based deployments.

“The capabilities of Radisys’ Engage Media Server align with our cloud strategy and provide the performance and flexibility we need to continue to innovate our offerings and meet our client demands,” said Sean Tinney, vice president of solution management, Enterprise Computing Solutions, Unisys. “Radisys’ Engage Media Server not only delivers the media processing capabilities required for our advanced voicemail services but also ensures seamless integration with our existing systems, setting a strong foundation for continued growth and innovation.”

Radisys’ Engage Media Server supports real-time audio and video services, including VoLTE and Unified communications (UC), as well as advanced analytics like speech recognition and video quality enhancements.

“Radisys’ Engage Media Server platform is capable of handling complex media processing while enabling integration and scalability,” said Al Balasco, Head of Media, Core and Applications Business, Radisys. “We are confident that this platform will help support Unisys in delivering voicemail experiences to their clients.”

Unisys will begin transitioning to the Radisys server this year with a large operator in Germany.
