Microsoft is set to eliminate one of enterprise collaboration’s longest-standing friction points. Starting June 2026, Teams Rooms on Android devices will natively support joining third-party external meetings via Session Initiation Protocol (SIP), a move tracked under Microsoft 365 Roadmap ID 558539 and confirmed across official Microsoft communications channels.
For years, organizations that standardized their conference room hardware around Microsoft Teams Rooms on Android faced an awkward reality: they could not seamlessly join meetings hosted on competing platforms like Zoom, Cisco Webex, or Google Meet without resorting to clunky workarounds such as plugging in a personal laptop, maintaining dual-purpose hardware, or relying on limited Direct Guest Join capabilities with inconsistent user experiences.
That changes with the SIP integration, now in active development. Microsoft is embedding SIP-based cross-platform meeting joins natively into the Android Teams Rooms environment, enabling room hardware to communicate directly with external conferencing services without requiring additional devices, secondary software installations, or complex IT reconfiguration.
The significance of this update extends beyond convenience. As hybrid work models become the enterprise norm, the pressure on IT teams to support seamless multi-platform collaboration has intensified.
Organizations that collaborate regularly with clients, vendors, government partners, or contractors who operate on different video conferencing ecosystems have been particularly exposed to this gap.
Microsoft Teams Rooms Android
Session Initiation Protocol (SIP) is a widely adopted, open industry standard for initiating, managing, and terminating voice and video communication sessions across diverse networks.
By integrating SIP support natively at the Android Teams Rooms device level, Microsoft removes the dependency on WebRTC-based Direct Guest Join, which has historically delivered limited in-meeting controls and lower video fidelity.
When the SIP join feature is active, users can walk into any configured conference room and dial directly into a Zoom, Webex, Google Meet, Amazon Chime, RingCentral, or any other SIP-compatible meeting, all from the same familiar Teams Rooms interface.
The system automatically uses SIP when a meeting invitation includes a SIP video address. If no SIP string is present, Teams Rooms falls back to Direct Guest Join over WebRTC as a contingency.
Enhanced capabilities enabled by the SIP pathway include up to 1080p video quality, dual-screen support, various meeting layout options, and HDMI ingest, all features unavailable through basic WebRTC-based guest joins.
The technical leap is significant for organizations that have high-bandwidth, high-fidelity video requirements across executive boardrooms and large conference spaces.
This SIP capability for Android-based rooms also extends what has been available on Windows-based Teams Rooms for some time. Microsoft is now closing the interoperability gap between its two device operating environments, ensuring a consistent cross-platform experience regardless of the hardware type deployed.
Access to SIP-based third-party meeting joins is not universal across all Teams Rooms license tiers. Microsoft has explicitly tied this capability to the Teams Rooms Pro license, positioning it as an enterprise-grade feature for organizations that already invest in advanced device management, enhanced meeting experiences, and premium interoperability infrastructure.
Teams Rooms Pro delivers a broader suite of capabilities beyond SIP, including intelligent audio and video processing, remote device management, conditional access policies, front-row and large-gallery meeting layouts, and detailed device analytics.
The SIP interoperability feature integrates seamlessly with this tier’s focus on maximizing room utilization and reducing administrative overhead.
Organizations running Teams Rooms on the Basic tier will not have access to this feature. They should evaluate whether a Pro license upgrade aligns with their cross-platform collaboration needs ahead of the June rollout.
Microsoft is rolling out SIP-based meeting joins across a broad set of cloud environments. The feature is confirmed for Worldwide Standard Multi-Tenant deployments as well as specialized government instances, including GCC (Government Community Cloud), GCC High, and the Department of Defense (DoD) environment.
This deliberate inclusion of government cloud environments is strategically significant. Federal agencies, defense contractors, and regulated industries operating under strict data sovereignty and security compliance requirements have historically been excluded from or delayed in adopting cross-platform integrations due to classification concerns.
By extending SIP support to GCC High and DoD instances, Microsoft signals that interoperability is not being built at the expense of compliance.
The native implementation within the Teams environment also means that external meeting joins operate within the existing security framework, preserving authentication policies, encryption standards, and governance controls that IT administrators already have in place.
The general availability rollout is scheduled to begin in early June 2026, with completion expected by mid-August 2026. Microsoft updated this timeline on May 4, 2026, extending the original completion target from early June. The feature is off by default and must be explicitly enabled by IT administrators.
Microsoft recommends the following preparation actions before the feature goes live:
- Audit current Teams Rooms Pro licensing across all Android-based room devices
- Test the feature on lower-ring devices ahead of broad deployment
- Identify user groups that frequently join third-party external meetings
- Update internal documentation and helpdesk runbooks
- Prepare user-facing educational materials on the new join workflow
Pexip is the Cloud Video Interop (CVI) partner that powers the SIP calling plan required to activate this capability. As part of the deployment setup, organizations will need to engage Pexip’s Connect for Teams Rooms solution.
