SRT will be available alongside **Real‑Time Messaging Protocol (RTMP)** , the existing inbound streaming protocol commonly used with external encoders. Adding SRT provides event organizers with improved reliability and flexibility, including support for backup streams with automatic failover, to help ensure smoother delivery for high‑visibility broadcast events without increasing setup complexity.\n\nThis message applies to Teams for Windows desktop and Teams for Mac desktop and is associated with Roadmap ID 554931.\n\n**[When this will happen:]**\n\n  * Targeted Release: Rollout begins in**early June 2026** and is expected to complete by **mid-June 2026**\n  * General Availability (Worldwide, GCC): Rollout begins in **mid-June 2026** and is expected to complete by**late June 2026**\n\n\n\n**[How this affects your organization:]**\n\n**Who is affected:**\n\n  * Organizations that host **Microsoft Teams town halls or live events** using **external encoders**\n  * Event producers and administrators responsible for configuring broadcast streams\n\n\n\n**What will happen:**\n\n  * Organizers can use **SRT as an alternative to RTMP** for inbound streaming\n  * Events can be configured with a **primary and backup SRT stream** with automatic failover\n  * Existing RTMP workflows remain supported and unchanged\n  * The feature is **available by default** ; no admin policy changes are required\n  * **No impact to users** attending events\n\n\n\n**[What you can do to prepare:]**.\n\n  * Review encoder capabilities to confirm **SRT support**\n  * Ensure you have access to port `49891 `and the domain `*.rtmpingest.mcr.teams.cloud.microsoft.com`.\n  * Update internal event‑production documentation to include SRT as a supported option\n  * Inform event production teams that a **backup stream with automatic failover** is now available for Teams town halls\n\n\n\n**Learn more:** Manage RTMP-In for Teams meetings, webinars, and town halls - Microsoft Teams | Microsoft Learn (will be updated before Targeted Release begins)\n\n**[Compliance considerations:]**\n\nNo compliance considerations identified, review as appropriate for your organization.",
