Hello @Noack, Jan,
Good day! Thank you for posting your valuable question on Microsoft Q&A forum.
Based on your description, I understand that Microsoft Teams continues to ring even after the call has been answered, and the ringing only stops when the desktop app is completely closed. This issue appears to affect only some users, and it happens during internal Teams-to-Teams calls.
Please let me know if I misunderstood any part of your issue or if there are additional details you'd like to share.
To help us provide the most accurate and effective solution for this ringing issue, could you please share a bit more detail about your setup:
- Which Teams client are you using (Teams for Windows, macOS desktop app, or Teams Web?)
- Do you use Teams only on this desktop device, or are you also signed in on mobile or any other device?
- Does the ringing issue happen for:
- All incoming calls?
- Only specific callers?
- Only Teams-to-Teams?
- Call queue or auto-attendant calls?
- Does the ringing also continue if you answer via Teams Web (https://teams.microsoft.com)?
- Are you using any Bluetooth or USB audio devices?
- What operating system and version are you on (Windows 10/11, macOS Monterey/Ventura/Sonoma, etc.)?
This additional context will help us understand your environment and the steps already taken, so we can tailor the guidance to resolve the issue effectively.
In the meantime, here are some basic checks you can try:
1. Clear the Teams cache manually
This resolves the issue for many affected users.
On Windows:
- Navigate to your Taskbar and look for the Microsoft Teams icon. Right-click the icon and choose Quit. This will force the Teams app to quit.
- Next, copy and paste the following location into File Explorer: %appdata%\Microsoft\Teams, and delete the contents of the entire folder.
- Restart Microsoft Teams by opening the application and logging back in.
On a Mac:
- Right-click the Teams icon in the taskbar and choose Quit.
- Next, delete the directory ~/Library/Application Support/Microsoft/Teams.
- Restart Microsoft Teams by opening the application and logging back in.
On Mobile device (iOS/Android)
There’s no manual cache clearing option, but you can:
- Sign out and sign back in.
- Or uninstall and reinstall the app to reset the cache.
Note: Deleting the cache won't remove Microsoft Teams from your device, but will remove the web client cache, icons, thumbnails, local message history, your Teams display images, and any other Teams add-ons.
2. Disable any call forwarding or simultaneous ring settings
- Open your Teams desktop app
- Click on the three dots button next to your profile picture > Settings
- Navigate to Calls and toggle Forward all calls to voicemail to OFF

3. Repair Teams app for Windows device:
If the users use Windows devices, you can try to Repair Teams app.
- Press Windows + I to open Windows Settings
- Navigate to Apps > Installed apps and search for Teams app
- Click on the three dots next to the app > Advanced options

- Scroll down and click Repair
