Teams – Audio Conferencing

Hi there

In this post I’m covering the Audio Conferencing feature at Microsoft Teams

You use Audio Conferencing licenses when you need to add a regular phone number call into your Microsoft teams meetings.

You can add phone dialing capability to online meeting or host phone only conference call using this feature.

Audio conferencing is licensed per user so there is a small per user fee for each account that you attach the feature to.

Once you have the Team’s app and new Team’s meeting button in Outlook and you are able to create online  Team’s meetings the only difference is that when audio conferencing is enabled you will now see a phone appear in body of your Team’s meetings invites.

You can Try Audio Conferencing as Part of Office 365 Enterprise E5 free trial program.


  1. Have your Office 365 Tenant ready and Microsoft Teams Operational with basic features deployed to users.
  2. Assign for the Office 365 Enterprise E5 free trial program – click here.
  3. Wait for the Conference bridges options (menu) to appear under Meetings Tab on Teams Admin Portal OR go the Legacy Portal under Teams Admin Portal (Left Tab) after Planning Tab section and check the following
    1. Under Skype for Business admin center
    2. Click on audio conferencing
      1. You have tree options to check: Microsoft bridge, Microsoft bridge settings and users.
      2. Under Microsoft bridge (from left to right) you should be able to see the phone numbers used with this conference bridge on different countries globally.
        1. Check which number is your default based on your Office 365 tenant E5 trial activation information (Microsoft set’s your default number as the closest address you’re located , where your Office 365 Tenant is activated on).
      3. Under Microsoft bridge settings (the one in the middle) you should see the meeting join experience and security options for joining meetings using Audio Conferencing.
      4. Under users, you should see which Audio Conferencing users has its default toll number (default conference bridge number) from Microsoft. All other licensed users (Teams users) will also show up on this users screen. Click on the drop-down menu to use the predefined search options:
        1. All
        2. All conferencing on << pick this one.
        3. All conferencing off
        4. Conferencing Provider – Microsoft
        5. Conferencing Provider – Other
        6. Users ready to be moved to Office 365 Audio Conferencing
          TIP! – if all these steps worked for you and you can see your current licensed users you can proceed with Sending invitations out to evaluate your audio conferencing joining experience.
  4. Pick the Audio Conferencing users list and test the following:
    1. Open MS Teams (client or web client)

    3. Create a new Meeting invitation
