Try or purchase Audio Conferencing in Microsoft 365 for Microsoft Teams

Sometimes users in your organization need to use a phone to call in to a meeting. Microsoft Teams includes the Audio Conferencing feature for just this situation. Users can call in to Microsoft Teams meetings using a phone, instead of using the Microsoft Teams app on a mobile device or PC.

You only need to set up Audio Conferencing for users who plan to schedule or lead meetings. Meeting attendees who call in to the meeting don't need any licenses assigned to them and don't need other setup.

For pricing info, see Pricing for Audio Conferencing.

Step 1: Buy and assign Audio Conferencing licenses

You must be a billing administrator to perform these steps.

To buy and assign user Audio Conferencing licenses

1. Find out if Audio Conferencing is available in your country/region. Country and region availability for Audio Conferencing and Calling Plans.

2. Get your Audio Conferencing licenses. If you want to:

   • Try it before you buy it: you can sign up for an Office 365 Enterprise E5 free trial that includes Audio Conferencing. See Office 365 Enterprise E5 Trial.

   • Buy it: see Microsoft Teams add-on licensing.

3. Assign licenses to users in your organization who will schedule or lead meetings.

4. If you purchased Audio Conferencing add-on licenses and Communications Credits licenses, assign these licenses to the appropriate users as well. For instructions, see Assign Microsoft Teams add-on licenses.

To buy and assign pay-per-minute Audio Conferencing licenses

If you're a Volume and Licensing customer, you can get pay-per-minute Audio Conferencing licenses. For more information on pay-per-minute Audio Conferencing licenses, see Audio Conferencing pay-per-minute.

1. Find out if Audio Conferencing is available in your country/region. Country and region availability for Audio Conferencing and Calling Plans.

2. Get your Audio Conferencing licenses. To acquire pay-per-minute licenses, contact your account representative.

3. Set up Communications Credits for your organization for your organization. To set up Communications Credits, see What are Communications Credits?

   Important

   If Communications Credits aren't set up, Audio Conferencing doesn't work for users with pay-per-minute licenses.

4. Assign licenses to users in your organization who will schedule or lead meetings.

   Note

   If you have Audio Conferencing pay-per-minute licenses, you must also assign a Communications Credits license separately to each user.

Step 2: Set the Audio Conferencing provider for users who lead or schedule meetings

When you assign an Audio Conferencing license to users in your organization who don't have Teams integrated with a third-party Audio Conferencing provider, they're automatically set up for Audio Conferencing. You don't need to set their Audio Conferencing provider.

If you have users set up with a third-party Audio Conferencing provider, you must change the provider of those users to Microsoft. To change the provider for a user, see Assign Teams add-on licenses to users.

Step 3: Other admin tasks

Consider the following optional configuration tasks:

1. Customize meeting invitations. The dial-in numbers assigned to a user are automatically included in the meeting invitations that are sent to attendees. You can also add custom help and legal links, a text message, and a small company graphic.

2. Set the phone numbers included in meeting invitations. Specify the phone numbers that appear in meetings scheduled by a user.

3. Set the auto attendant languages for Audio Conferencing. Configure the languages that the Audio Conferencing auto attendant uses to greet callers when they dial in. This setting applies only if you use Microsoft as your Audio Conferencing provider.

4. Set the PIN length for Audio Conferencing meetings.
