“With the ongoing migration of telecommunication services to IP network architectures, including 3G, IMS and LTE, the media server plays a critical role in delivering scalable, real-time IP voice and video media processing,” said Diane Myers, directing analyst, service provider VoIP and IMS, Infonetics Research. “Radisys continues to deliver innovative media server product enhancements in their efforts to maintain and grow their leadership position.”

In 2010, Radisys announced its Integrated Mobile Media Server (IMMS), enhancing mobile service providers’ ability to grow new revenues from the explosion of 3G mobile video services and 4G Long Term Evolution (LTE) deployments.

Adoption of these solutions by our service provider customers and application partners is validation of our open standards-based media server products being successfully deployed across multiple applications and network rollouts. We look forward to continued success in 2011 and fulfilling our ongoing commitment to deliver the revenue-generating products and services that our customers desire.”
