Set up Audio Conferencing for Skype for Business and Microsoft Teams
Sometimes people in your organization will need to use a phone to call in to a meeting. Skype for Business and Microsoft Teams include the audio conferencing feature for just this situation! People can call in to Skype for Business or Microsoft Teams meetings using a phone, instead of using the Skype for Business or Microsoft Teams app on a mobile device or PC.
You only need to set up Audio Conferencing for people who plan to schedule or lead meetings. Meeting attendees who dial in don't need any licenses assigned to them or other setup.
For frequently asked questions about Audio Conferencing, see Audio Conferencing common questions.
Step 1: Find out if Audio Conferencing is available in your country/region
Go to Country and region availability for Audio Conferencing and Calling Plans and select your country or region to get availability information about Audio Conferencing, as well as information about Phone System, Calling Plans, toll and toll-free numbers, and Communications Credits.
Step 2: Get and assign licenses
For Audio Conferencing, you need a license for each user who will set up dial-in meetings. To learn which licenses you need to buy for Audio Conferencing and how much they will cost, see Skype for Business and Microsoft Teams add-on licensing.
After you buy the Audio Conferencing licenses, you will ned to assign them to those people in your organization who are going to schedule or lead meetings. See Assign or remove licenses for Office 365 for business you purchased to the people in your organization who are going to schedule or lead meetings.
We also recommend that you assign Communications Credits licenses (they don’t cost anything) to the same people you assigned licenses to in the previous step. To learn how to set up Communications Credits, see Set up Communications Credits for your organization.
You can also set up pay-per-minute Audio Conferencing. Go here to find out more about how to use them.
Step 3: Get service numbers for your conferencing bridges
For Audio Conferencing, you can’t use phone numbers for users; you will need to get service numbers. You can get either toll or toll-free service numbers for your conferencing bridges. There are three ways to get toll and toll-free service numbers:
Use the Skype for Business admin center. For some countries/regions, you can get service numbers for your conferencing bridges using the Skype for Business admin center, see Getting service phone numbers.
Port your existing service numbers. To port or transfer existing numbers from your current service provider or phone carrier to Office 365. You can see Transfer phone numbers to Office 365 or Manage phone numbers for your organization for more information to help you do this.
Use a request form for new numbers. Sometimes (depending on your country/region) you won't be able to get your new service numbers using the Skype for Business admin center, or you will need specific phone numbers or area codes. If so, you will need to download a form and send it back to us. See Manage phone numbers for your organization for more information.
Step 4: Assign a service number to the conferencing bridge
Once you get your toll and/or toll-free phone numbers for your conferencing bridge, you need to assign the numbers so they can be used on meeting invites.
To assign a new phone number to your audio conferencing bridge, go to the Office 365 admin center > Admin centers > Skype for Business > Voice > Phone numbers, select the phone number, and click Assign.
