If you use USB headsets, speakers, or other peripheral devices, you can speed and simplify common call control tasks in Teams by using the physical buttons on these devices.

Note: The call control features described in this article are supported for the installed version of Teams on Windows and Mac.

Known issues


You can use the buttons on certified Teams devices to do the following:

  • Answer calls

  • Respond to meeting nudges

  • Adjust audio volume

  • Mute and unmute yourself

  • Bring the meeting window to the foreground

  • Place calls on hold and activate held calls

  • Juggle multiple calls

  • Leave calls and meetings



Teams devices contain a handy “alert” button that lights up to signal meeting starts, missed calls, and voicemail. Press the button to quickly access the on-screen Join meeting button or check missed calls and voicemail.

Note: Some wireless devices display the alert on the USB dongle rather than on the headset itself.

Dial pad and call status

Dial pads and call status displays are now supported for Polycom CX300 and Plantronics Calisto P540, and for new desk phone models coming soon.

With this update, users who are part of the TeamsOnly upgrade policy can use the dial pad to make calls and use in-call DTMF (dual-tone multi-frequency) signaling, which is the sound phones make to convey the number or key you touch.

Also, these devices display call status information such as duration and caller ID.

Secondary ringer

If you have multiple connected devices, you can set one as your secondary ringer. This device will ring, along with your primary device, when you get a call.

As always, you can answer incoming calls or join meetings on any connected device—not just the ones that ring.

Known issues

While most devices that received Skype for Business certification, or older Lync or Office Communication certifications, will work with Teams, some may not work as expected.

We work with our partners to address issues in devices that are actively sold, but not all legacy devices are updated. For optimum performance we suggest using Teams certified models.

The following older devices have known issues and are not recommended for use with Teams.


  • APU 75

  • C220-M

  • Calisto 800 Series


  • CX100

Non-certified device models

Some device vendors offer both a model for Microsoft certification (designated as “Certified for Microsoft Teams,” or for an earlier product like Skype for Business) and a similarly-named model for use with other communication clients. For best results, be sure to use the model that is Microsoft certified.

Device vendor software and third-party calling apps

Device vendors may offer third-party software such as Poly Hub or Jabra Direct to update firmware and control settings on the devices. In addition, some people may be using other third-party apps. Sometimes this software includes communication features that interfere with device button functionality in Teams.

If any issues are found when using a device with Teams, try closing any third-party software as a first troubleshooting step.
