What is Teams Phone Fix?
'Teams Phone Fix' is a Firefox add-on created to bypass the error message in Microsoft Teams that prevents phone calls in unsupported browsers. This add-on is particularly beneficial for Linux users, as it fakes the browser's user agent to imitate as Microsoft Edge, enabling them to use Microsoft Teams without any disruption.

Teams Phone Fix

Microsoft released an official Teams for Linux Client. It is strongly recommended to use the official application.

This Firefox addon fixes the error message in Microsoft Teams claiming your browser is not supported to do phone calls. It is especially intended for Linux users using Firefox, as Microsoft seems to block browsers which are not in their scope.

This Firefox addon might also run under Windows and MacOS, but i did not test that. Therefore use this addon at your own risk, as your browser is not offically supported by the Microsoft Teams website.

How does it work?

The extension fakes the browser's user agent to impersonate as Microsoft Edge or other browsers,

It does literally what it says: fake user agent to bypass Microsoft intentional block (there're other add-ons that purportedly do that, but this one works out of the box and does not require a video tutorial). Don't expect it to fix Teams bugs or accomplish world peace. Also, you may need to restart Firefox after installing the add-on (it wasn't functional for me until I did, and it even crashed Firefox). By the way, the official Teams for Linux Client mentioned has been long abandoned by Microsoft.
