RM561648Microsoft Teams: Town hall media optimization for VDI attendees

What’s new

Teams now supports audio and video offloading for Town hall attendees in VDI environments that are using the new optimization. Media streams are offloaded directly to the user’s local device, improving performance and delivering a high definition viewing experience while reducing virtual desktop resource usage.

Who it applies to

• Windows endpoints only using the new VDI optimization

• Supported VDI platforms:

o Azure Virtual Desktop and Windows 365

o Citrix

o Omnissa

o Amazon WorkSpaces

What stays the same

All attendee interactivity features remain supported, including captions, DVR, reactions, streaming chat, and Q&A.

Additional details

First party and third party eCDNs are supported. When enabled, the attendee’s endpoint establishes a direct peer to peer connection using the local device network, avoiding virtual desktop double hop traffic.

Action required

No action is required if the new optimization for Microsoft Teams is already enabled.
