You will need to have a few basic audio devices installed on your computer to use Teams. At a minimum, your computer will need speakers and a microphone.

Choosing your Audio Device

When choosing your audio device, consider ease of use, comfort, reliability, and quality. Several types of audio devices will work with Teams:

Built in Speakers and Microphone

Most modern laptops and PCs come with a built-in set of speakers and a microphone that can be used with Teams. This is not an ideal solution, because the speakers will allow others to hear your calls and meetings, and the microphone usually picks up ambient room noise. However, it may be a good option if audio quality and privacy are not a concern.

USB or 3.5mm Wired Headsets

In terms of reliability and ease of use, this may be your best choice.These types of headsets are very common. They are easy to install and provide a reliable connection. The price varies depending upon the style and quality you choose.

Wireless Headsets

Wireless headsets are quickly becoming a popular device when working from home. They provide maximum flexibility, allowing you to move freely without being tethered to your computer. They require a wireless connection to your device, which involves additional setup. In addition, the wireless headsets need to be charged frequently, and charge times vary by device. As with USB and traditional wired headsets, the price varies depending upon the style and quality you choose.

Installing your Audio Device

Consult the product documentation for installation steps and verify your audio device is working properly prior to running Teams.

Selecting your Audio Device in Teams

You will need to select your audio device within Teams in order to use it. Note that the default may be set to 'Custom Audio Device,' which will use your built-in default audio devices.

1. Open Teams.

2. Click your account image/initials in the upper right-hand corner, and click Settings.

3. Click Devices to display your audio device menu.

4. Choose your preferred audio device from the Audio devices drop-down menu. In the exampe below, the user has chosen a Plantronics BT600 headset.

Audio Conferencing in Teams

With Audio Conferencing, participants use a regular phone to take part in Teamsmeetings—either by dialing in to the meeting from their phone or by usingdial-out functionality from within the meeting. Review the following resourcesto learn more about Audio Conferencing:

Scenario – Audio Conferencing

Garth works at Contoso, a company that has multiple offices. Garth frequentlyneeds to connect with people in other office locations, and because he oftenworks from home or goes out on the road, he’s a huge fan of Teams meetings. WhenGarth sends out a meeting invitation, it automatically adds information forAudio Conferencing. This makes the following scenarios possible:

  • Alice wants to attend Garth’s meeting but she’s on the road and has noaccess to a reliable network. Therefore, she joins the meeting by using thedial-in coordinates from the meeting invitation. During the dial-in process,she uses her PIN to authenticate, so she’s recognized by the system as“Alice.”
  • Bob, who’s currently at a hotel, joins the meeting by using the Teams clienton his PC. Unfortunately, the audio quality over the internet connection inthe hotel isn’t great, So Bob dials out to his own phone number from themeeting to join via the public switched telephone network (PSTN).
  • If the meeting participants decide during the call that they want to addusers at a different phone number, they can just dial out to the phonenumber and bring additional people into the meeting.
  • Other users can also join from the Teams client on their PC, Mac, or mobiledevice.

In Teams, meeting organizers can end a meeting for all meeting participants. This is useful in scenarios such as the following:

  • Educators can ensure that students don't stay in a meeting unsupervised after a class is finished.
  • For meetings that are being recorded, such as webinars, meeting organizers can ensure that the recording ends when the meeting ends.
  • Ending a meeting for all participants can help reduce your organization's PSTN usage and billing.

For example, when the meeting is finished, Garth can click End meeting from within the meeting in Teams to end it and remove all participants from it.

Considerations for Skype for Business customers

If you’re already using Skype for Business, you’ll need to consider thefollowing:

Skype for Business Server–homed users

If you’re using Skype for Business Server, Teams meetings scheduled by users who are homed on Skype for Business on-premises will not include PSTN meeting coordinates. If you assigned Audio Conferencing licenses to these users prior to March 1, 2019, you might need to unassign these licenses, wait for 2 hours, and then reassign them for the users to see the PSTN meeting coordinates.

Skype for Business Online–homed users

If users are homed in Skype for Business Online and are already enabled for Audio Conferencing, they’ll automatically be enabled for Audio Conferencing inTeams. The PIN they use for authenticating in meetings when they dial in will be the same for Skype for Business and Teams.

Envision Audio Conferencing

The practical guidance covers in detail what’s required to plan and successfullyimplement Audio Conferencing. Review the following articles to understand thesetechnical planning steps:

Exercise – Configure Audio Conferencing

In this exercise, you’ll have the chance to test Audio Conferencing in Teams.Although we don’t describe how to perform every action, we recommend somescenarios to try out.


  • An Office 365 organization with appropriate licenses to use Teams
    • We strongly recommend that you use a dedicated test tenant.
    • If you don’t have a test tenant, you can sign up for a trial tenant atOffice 365 Enterprise E5Trial.
    • Don’t run any tests in your production environment. Changing settings orpolicies might have a negative impact on all users and might affecttheir user experience.
  • At least two endpoints
    • This can be two PCs, but you can also use the client on your mobilephone.
    • A phone that can dial in to meetings and be dialed out to

Suggested scenarios to test

  • Enable users for Audio Conferencing.
  • Set different conference bridge numbers for different users.
  • Change the default conference bridge number for the tenant.
  • Change settings for the conference bridge number (different languages).
  • Change global settings for conference bridges (meeting entry and exitnotifications, PIN length, email notifications).
  • Observe the email being sent out to users.
  • Schedule Teams meetings, and review the meeting invitation.
  • Join a meeting from a phone.
  • Dial out from a meeting to a phone.
  • Use dual-tone multi-frequency controls while in a meeting to mute and unmutea phone.
  • End the meeting for all users.

Drive value

From a reporting perspective, you have two areas to look at:

  • Usage: How many meetings take place?
  • Quality: What is the quality of the meetings?
Teams AudioTeams Audio

You should carefully monitor both areas:

Teams Audio Low

  • Low usage means that users, for one reason or another, aren’t using theproduct. You can only determine the reasons by investigating further.Reasons can range from the perception that meetings are falling short ofuser requirements, to a lack of awareness or training, to quality problems.
  • Low quality, on the other hand, means that there are issues withconnectivity between users and Office 365. Low quality can lead to bad userexperience and lower usage. Refer to Microsoft 365 Reports in the Admin Center - Microsoft Teams useractivity(estimated reading time 5 minutes) to learn more about the usage reports.

Managing quality is outside of the scope of this training, but see the followingtraining material:
