MMR Call Redirection for Azure Virtual Desktop, Windows 365 now available
Today, I am pleased to share the launch of Multimedia Redirection (MMR) Call Redirection for Azure Virtual Desktop and Windows 365. Call Redirection allows users to enjoy audio calls on Windows delivered from the cloud just as they would through their local Windows OS.
What is MMR Call Redirection?
Call Redirection redirects WebRTC calls from Azure Virtual Desktop session hosts and Windows 365 Cloud PCs to local client devices to reduce latency and improve call quality. Prior to this release, customers may have experienced interruptions to their calls that impaired productivity. With the release of Call Redirection, customers can have like-local audio calls while using WebRTC-based calling apps on Azure Virtual Desktop and Windows 365.
MMR Call Redirection extension pop-up
MMR Call Redirection also works seamlessly with Windows App, a unified app that provides a gateway to securely connect to Windows on any device or app across Windows 365, Azure Virtual Desktop, Remote Desktop, Remote Desktop Services, Microsoft Dev Box, and more. This provides users with an enhanced video and audio experience. Learn more about Windows App.
