Microsoft Teams Rooms

Microsoft Teams Rooms (MTR) is Microsoft's dedicated room conferencing platform — running on Windows or Android devices paired with certified hardware from Poly, Logitech, Yealink, and others. Its network footprint is notably compact: Microsoft has consolidated Teams media to just UDP 3478–3481 plus TCP 443 for signalling, making it one of the more straightforward UC platforms to configure at the firewall.

Scope: Microsoft Teams Rooms — select the deployed product/version; optional services require separate selection.
