Microsoft Teams Cloud Video Interop (CVI) service is a Microsoft Qualified third-party solution that allows standards-based third-party meeting rooms (telepresence) and personal video devices (VTCs) to join Microsoft Teams meetings. Many organizations have already invested in legacy video teleconferencing devices which they may want to continue using. Cloud Video Interop provides a cloud-based solution with little or no on-premise infrastructure that allows these existing solutions to participate in Teams meetings. This blogpost walks through step-by-step the configuration of Poly's RealConnect CVI service for Teams. Full details on how to configure CVI can be found in this MSDocs webpage.
