Microsoft Teams Adds SIP Cross-Platform Join, Rollout Starts June 2026

Microsoft is rolling out a major interoperability upgrade for Microsoft Teams, enabling Teams Rooms on Android devices to join third-party meetings using SIP. As reported via Neowin, the feature appears under Roadmap ID 558539 and targets enterprise environments that rely on multiple video platforms.

Native SIP support replaces web-based joining

The update introduces SIP (Session Initiation Protocol) support, allowing Teams Rooms on Android to connect directly to platforms like Zoom and Cisco Webex without relying on browser-based workarounds.

This marks a shift away from Direct Guest Join, which uses web layers and often limits functionality. With SIP, devices can dial into meetings using video address links or connect directly through protocol-level interoperability.

The move also brings Android-based Teams Rooms closer to Windows setups that already support advanced integrations like Pexip CVI.

Rollout starts June with global availability by August

Microsoft plans to begin rollout in early June 2026, with full worldwide availability expected by mid-August. Once complete, the feature will reach General Availability status.

However, the capability will not activate automatically. Organizations must enable it manually, and it requires a Teams Rooms Pro license, as outlined in Microsoft documentation.

Enterprise-focused feature with limited scope

The SIP-based join feature applies only to Teams Rooms on Android. Other Teams platforms, including desktop and mobile apps, will not support this functionality at launch.

Microsoft recommends that IT administrators test the feature on select devices before wider deployment. Preparing internal documentation and updating helpdesk workflows will also help avoid disruptions during adoption.

Designed for interoperability without compliance changes

Microsoft says the feature does not introduce compliance or policy changes. Instead, it focuses on improving interoperability across enterprise meeting environments, where multiple conferencing platforms often coexist.

The update reflects a broader push to make Teams more flexible in mixed-platform workplaces, especially for organizations managing diverse collaboration tools.

In other news, hackers have reportedly abused Teams to deploy Snow malware, while a recent Edge bug has disrupted meeting access for some users. Microsoft also faced backlash after introducing a new “Unlock Premium” button inside Teams.
