Teams supports controlling your calls and meetings using the physical buttons on your USB headsets and peripheral devices. Use controls such as mute, unmute, answer, and volume up or down.
We've seen issues with the devices in the list below, and the call controls might not work as expected. We're working with our partners to address these issues, so make sure to check back here regularly for updates.
Note: If you've been upgraded to Teams calling but haven't updated Skype for Business, you should close Skype for Business when using Teams to make sure your call controls work with your USB headsets and peripherals.
