If your meeting rooms run on Android and you’ve been watching Windows Teams Rooms users get native SIP interop since 2024, that wait is nearly over.
Microsoft has begun rolling out SIP-based cross-platform join for Teams Rooms on Android as of early June, with general availability worldwide expected by mid-August 2026. Once fully rolled out, Android Teams Rooms devices will be able to join meetings on Zoom, Cisco Webex, Google Meet, Amazon Chime, RingCentral, and any other SIP-enabled platform directly from the room’s Teams interface, with no secondary device or workaround.
It arrives off by default, so admins need to enable it. For IT teams managing Android room estates, now is the time to get ahead: test with lower-ring devices, check Pro licensing, and engage with Pexip on CVI provisioning before mid-August. Teams Rooms on Android has until now relied on Direct Guest Join for third-party meetings, a WebRTC-based approach with real capability limits. Pexip’s Connect for Teams Rooms brought SIP-based join to Windows devices in 2024. Until now, Android devices have been waiting.
SIP Join vs Direct Guest Join: What Changes in Practice
According to Microsoft Teams MVP Graham Walsh, SIP interop delivers 1080p video and dual-screen support with HDMI ingest. Direct Guest Join tops out at single-screen 720p with no HDMI content sharing.
Direct Guest Join works by embedding the third-party platform’s web experience inside the Teams Room interface. It needs no additional licensing and works across Teams Rooms Basic and Pro. What it does not deliver is the consistent, protocol-level experience SIP provides: native one-touch join from the calendar, in-room content sharing via HDMI, full dual-screen layout, and the same interface behaviour regardless of which platform hosts the meeting.
Writing in March 2026, Anders Løkke of Pexip noted: “Most organisations do not operate a single room type. Many have mixed Windows and Android-based Teams Rooms and have been waiting for an interoperability solution that works across their full room estate.”
“At Pexip, we believe all meeting rooms need to connect to all meeting platforms. Bringing Pexip Connect for Teams Rooms to Android is a natural step, helping more organisations deliver a seamless experience across their rooms and devices.”
When SIP calling is enabled, Teams Rooms prioritises SIP over WebRTC when a meeting invitation includes a SIP dial string. If the invite has no SIP address, the device falls back to Direct Guest Join, so existing workflows stay intact.
Why Android Rooms Lagged, and Why It Matters Now
Teams Rooms runs on two platforms, Windows and Android, and has always shipped with Windows ahead on advanced capabilities. SIP/H.323 dialling was one of the more visible gaps: as recently as February 2026, Microsoft’s own device comparison documentation listed SIP/H.323 support as Windows-only.
Android-based devices now hold a significant share of enterprise room deployments. According to Futuresource Consulting, Android video bars made up nearly half of all global video bar volumes in 2024 and accounted for close to 70 percent of total market value. The Android form factor, self-contained video bars with fewer in-room components, suits organisations rolling out collaboration technology across smaller meeting spaces at scale.
Microsoft’s Device Ecosystem Platform (MDEP), designed to accelerate Android bar development, now counts Barco, Jabra, Lenovo, MAXHUB and Yealink among its adopters. Windows-based Teams Rooms have had SIP interop for over a year. Android has been catching up.
Licensing and Admin Requirements
Enabling this feature requires Teams Rooms Pro licensing: it does not work on Teams Rooms Basic. Organisations also need a SIP calling plan from a Cloud Video Interop (CVI) partner. Pexip is currently the only provider enabled for this feature. Pexip Connect for Teams Rooms is a paid add-on, and the licensing count must match between Teams Rooms Pro and Pexip Connect across the deployment.
Configuration requires adding a DNS TXT record for the Microsoft 365 domain, then applying a PowerShell policy with the Pexip provider tenant ID. The feature also needs Teams Rooms app version 5.2.115.0 or later.
Microsoft’s guidance in MC1294522 covers testing with lower-ring devices before broader rollout, preparing user-facing documentation, briefing helpdesk teams, and identifying users who regularly join meetings on other platforms.
Microsoft has confirmed no compliance considerations attach to the update, relevant to organisations in regulated industries weighing whether to enable the feature.
What This Means for Mixed-Estate Deployments
For organisations already running Pexip Connect on Windows-based Teams Rooms, extending to Android is straightforward: the same infrastructure carries over. For those yet to adopt a CVI solution, this is the point at which they will need to. Direct Guest Join remains available at no additional cost for meetings without SIP dial strings, but consistent, higher-quality cross-platform join across both Windows and Android rooms requires the CVI layer.
The rollout completes mid-August 2026. The Google Meet and Teams two-way interoperability announced at ISE 2026 points in the same direction: organisations that build their room estate around one platform still need those rooms to connect reliably to meetings hosted on others.
