If a user finds that their DIAL IN number in Teams is not showing in Teams Meeting invites, there are three things to do to solve it.

If you know what you are doing and have run through the more obvious stuff, just scroll down to #3 to see how we fix it.

Teams with audio conferencing invite missing dial in number

1 – Determine if this a Teams issue or an Outlook Issue

Make sure this is not really an Outlook problem by creating test meeting in OWA:
Microsoft Teams Audio Conferencing codes in Outlook Web Access OWA Webmail

    1. As the user, log into portal.office.com > click OUTLOOK then the CALENDAR icon, create a new meeting and toggle TEAMS MEETING on, then click SAVE
    2. In OWA or Outlook check the meeting to see if the dial in number appears
      1. if it does, you have an Outlook problem not a Teams problem
      2. if it does not, read on!

2 – Make Sure You User Has An Microsoft 365 Audio Conferencing License

As an administrator log into admin.microsoft.com/AdminPortal/Home#/ and verify that a license has been assigned to them:
Microsoft Teams Audio Licenses

3 – Disable then Endable Audio Conferencing in The Teams Admin Console

This solved our issue after several hours of troubleshooting.

As an administrator log into admin.teams.microsoft.com > USERS > find your user and notice if AUDIO CONFERENCING is set to on or off.

    1. If AUDIO CONFERENCING is ON, click EDIT then toggle it off, wait 5 minutes and then turn it back on
    2. Wait another 5 minutes and create a test Teams meeting again to see if the problem is resolved
      Microsoft Teams Audio Conferencing enabled toggle off on

Thanks so much. I came across this issue with a new user and this was the issue. Sorry it took so much of your time but thanks for sharing and saving us the time.

Didn’t work for me.

    We have just run through this solution with 2 unrelated clients. If you find a different solution, please notify us. Thanks for your comment.

I just got a 365 Audio Conferencing license, assigned to me (E3 user). On the Teams Users page, beside my name the Audio conferencing setting shows “Off”. When I click on my name, under the Account tab I don’t see any of the Audio Conferencing settings you do, I only see the Teams Upgrade settings.

How do I get it enabled? Do I have to change a policy?

btw, I’m a Global Admin

    Hi Nick;

    You should not have to change policies. Are you in Mixed Mode (I am thinking about your TEAMS UPGRADE comment)? If you are stuck you can open a free case with MS https://www.urtech.ca/2018/12/solved-how-to-open-a-free-support-ticket-with-365/

    Well… I know these comments are just over a year old, but I’m hoping sometime might see this. I am having the exact same problem as Nick. We have users with Audio Conferencing licenses that have had no problems at all.
    I have assigned new Audio Conferencing Licenses to 3 more users, but it still shows OFF for each of the users in the Teams Admin portal. There is no option to turn it on when I select one of the users and click edit. There is also not any Audio Conferencing options showing when I open the users profile in the Teams Admin portal. I am at a loss and Microsoft has been no help at all. Been dealing with this for several weeks now. Any ideas?

      Did you try making sure they are enabled for Skype?
