Updated September 19, 2025: We have updated the timeline. Thank you for your patience.
We’re introducing new customization options for Teams-certified phone devices that enhance how users manage incoming calls. With this update, users can personalize the behavior and ringtone for each assigned line key—choosing from ring only, ring with flash, or flash only. Unique ringtones can also be assigned per line key, making it easier to identify calls at a glance.
This feature is supported across touch, non-touch, and sidecar devices, giving users more control over their call experience. End users will be able to configure these settings directly on their devices. Admin-level controls are planned for a future release.
This change is associated with Roadmap ID 495451
[When this will happen:]
Worldwide/GCC Clouds: Rolling out from late July 2025 (previously mid-July) through mid-August 2025
GCCH Clouds: Rolling out from mid-August 2025 through end of August 2025
DoD Clouds: Rolling out from early September 2025 through late October 2025
[How this affects your organization:]
Users with Teams-certified phone devices will be able to customize how each line key alerts them, improving call management and reducing missed or misidentified calls. This feature is on by default for users with the latest Teams phone application update. No admin action is required at this time.
[What you can do to prepare:]
Ensure that Teams phone devices in your organization are updated to the latest application version to enable this functionality. Communicate this enhancement to your users and help desk teams so they are aware of the new customization options.
