Zoom Room Controller

Trio 8500 and 8800 systems, when optimized for Zoom Rooms, act as a controller via the system’s touch user interface and provide audio for Zoom Room meetings through the built-in speakers and microphones.

This software release runs Zoom Rooms Controller software 5.14.0 (1920) as embedded software. For more information on this Zoom release, see the Zoom Help Center.


For the latest setup instructions, see the Integrating Poly Trio Systems with Zoom Rooms Solution Guide at Poly Solutions for Zoom Environments.

Microsoft Teams

The Microsoft Teams application is included in this UC Software release for use on CCX 400, CCX 500, and CCX 600. The Teams version included may be updated independently of the UC Software version using the Teams Admin Center. 

For more information on Teams versions, see What’s new in Microsoft Teams.



IMPORTANT:    UC Software includes the Microsoft Teams base profile in every release; however, Microsoft support of a UC Software release depends on the version delivered by Microsoft through the Teams Admin Center.
