SIP Interop Comes to Microsoft Teams Rooms on Android (MTR-A) | What’s New & Requirements
Graham Walsh (Microsoft MVP, Neat) explains a new Message Center update introducing SIP interop for Microsoft Teams Rooms on Android, a capability previously available on Teams Rooms on Windows. Starting in early June 2026, it will be off by default and requires a Teams Rooms Pro license plus a Cloud Video Interop/SIP interop provider license (currently Pexip). SIP interop enables cross-joining third-party meetings (e.g., Zoom, Webex, Google) with improved experiences such as dual-screen HDMI content sharing and 1080p content, compared to Direct Guest Join’s single-screen 720p and no HDMI ingest. When enabled, the join button prioritizes SIP over Direct Guest Join. He notes availability via the TAP program first, then preview, with documentation and setup via a PowerShell policy and provider tenant ID.
