Microsoft Teams Rooms on Android will join Zoom and Webex meetings through SIP

Microsoft Teams Rooms on Android will soon let users join third-party meetings through Session Initiation Protocol, or SIP. The update applies to shared Teams Rooms devices running Android, not the standard Teams mobile app for personal phones.

Microsoft says the feature will let Teams Rooms on Android connect to supported external meeting services when an invite includes a SIP video meeting address. This means meeting rooms that use Android-based Teams hardware will be able to join platforms such as Zoom and Webex more directly.

The rollout is scheduled to begin in early June 2026 and complete by mid-August 2026. Microsoft says the feature will stay off by default and will require a Teams Rooms Pro license plus the right device configuration.

What Microsoft is adding

The new feature is called enhanced cross-platform join via SIP for Teams Rooms on Android. It gives Android-based Teams Rooms a more direct way to join meetings hosted outside Microsoft Teams.

SIP is a long-used signaling protocol for setting up real-time voice and video sessions. In this case, the meeting invitation must include a SIP video meeting address that the Teams Rooms device can use.

Microsoft already supports third-party meeting options for Teams Rooms, including Direct Guest Join and SIP-based join. The Android update closes part of the gap for organizations that use mixed meeting room hardware across Windows and Android.

Why this matters for meeting rooms

Many companies do not use one meeting platform everywhere. Employees may use Teams internally, while clients, vendors, contractors, or partner companies may send Zoom, Webex, Google Meet, or other third-party meeting invites.

That creates friction in conference rooms. Users often need workarounds, laptop sharing, browser joins, or extra room configuration to connect to meetings outside the company’s main platform.

With SIP join support, Teams Rooms on Android can become more useful in mixed collaboration environments. The room can stay centered on Teams hardware while still joining supported outside meetings.

What admins need to know

The feature will not turn on automatically. Microsoft says organizations need Teams Rooms Pro licensing and suitable device setup before users can join supported third-party meetings through SIP.

Admins should test the feature first on lower-risk rooms or pilot devices. Microsoft also recommends preparing user guidance and updating internal meeting room documentation before broader rollout.

Organizations should also identify users and rooms that often work with external companies. Those rooms may benefit most from SIP join support when the feature becomes available.

How SIP join differs from Direct Guest Join

Microsoft Teams Rooms supports different ways to join third-party meetings. Direct Guest Join relies on web-based guest meeting experiences for supported providers.

SIP join uses a SIP video address from the meeting invite. This approach is more common in enterprise video conferencing environments and can offer a more consistent room-based meeting flow when configured correctly.

The exact experience can still depend on the meeting provider, the Teams Rooms device, the license, and the organization’s configuration. Microsoft notes that Teams Rooms features can arrive on Windows and Android at different times.

Security and network preparation

• Confirm which rooms need third-party SIP join before enabling it broadly.
• Use Teams Rooms Pro licenses for rooms that require this capability.
• Test SIP join with common external meeting platforms used by clients and partners.
• Review firewall and network rules that could block SIP-based meeting traffic.
• Update room instructions so users know when to choose the third-party meeting option.
• Train support teams before the wider rollout reaches shared spaces.
• Review external meeting policies to reduce unnecessary exposure.

What users will notice

For end users, the feature should make external meetings easier to join from supported Android-based Teams Rooms. Instead of finding a workaround, users can join a supported third-party meeting directly from the room system when the invite includes the right SIP address.

This should help shared rooms that regularly host calls with external organizations. It also reduces the need for users to bring their own laptop just to bridge a meeting room into a non-Teams call.

Still, users should expect some limits. The feature depends on SIP details in the invite, Teams Rooms Pro licensing, device support, and admin configuration.
