M365 Changelog: Free for one year: users can join Team meetings via call-in number

MC224047 – You now have the option to activate one year of free dial-in Audio Conferencing for Microsoft Teams.

When this will happen

  • This offer is available now.
  • It expires on March 31, 2021.

How this will affect your organization

With Audio Conferencing, attendees can join Teams meetings from wherever they are, using a global dial-in number. This is useful when people need to join meetings from land line telephones or when they do not have internet access. The global dial-in number allows attendees to join via voice only.   

To take advantage of this offer, you acquire free licenses and then assign them users in your organization.

What you need to do to prepare

Consider the benefits of activating this offer with your organization. 

  • If you do not choose to activate the free offer, there is no impact to your organization.
  • If you activate dial-in Audio Conferencing, when licensed users create Teams meetings, the body of the meeting invitation will include a phone number that people can dial to join meetings. The person using the dial-in number does not need a license.

To activate free dial-in Audio Conferencing, from within Admin center go to Purchase services > Add-ons and then select the free Microsoft 365 Audio Conferencing Adoption Promo. 


Then assign the licenses to users in your organization.

If you choose to take advantage of the free offer, let the employees you have licensed know that their Teams meetings invitations will include a dial-in phone number.
