Teams Meetings do not include a phone dial-in

In order to get the dial in option, you need to get the Audio Conferencing add on license for each user.

The problem here is - you get your licenses from GoDaddy, they are a reseller of Microsoft's product. Your support would need to go through them. Microsoft unfortunately cannot support your account directly.

There's a chance GoDaddy's Teams license may not have the Audio Conferencing add on license. Ask them specifically if they have that. If they don't, and if this feature is deal breaker, transfer your Ms365 services out of GoDaddy directly into Microsoft instead. That way you can have everything Microsoft offers instead of being restricted to the resold SKU, plus you get support directly from MIcrosoft.

Dear @Bryan DS,

Good day, and I appreciate the clear explanation of your concern. As a forum moderator, I genuinely wish I could directly access your account or delve into the backend systems to diagnose and fix this for you. However, our role here is limited to providing general guidance and solutions that can be applied by users.

From my research, the Audio-Conferencing feature (also known as PSTN conferencing) is a separate add‑on license that must be added and assigned to users who schedule or create meetings. Without this add‑on, the dial‑in phone number and conference ID will not appear in the meeting invitation.

The good news is that this can be enabled directly by an administrator. The add‑on is relatively inexpensive and is designed specifically for the scenario you described.

Please follow these steps to enable dial‑in numbers (Audio Conferencing)

1.Sign in to the Microsoft 365 Admin Center

Go to admin.microsoft.com and log in with your admin email (the one you use for GoDaddy Microsoft 365).

2.Purchase or enable the Audio Conferencing add-on

• In the left navigation menu, click Marketplace
• On the Marketplace page, you will see tabs like All products, Add-ons, etc.
• Click the Add-ons tab (or filter by "Add-ons").
• Search for "Audio Conferencing" or "Microsoft Teams Audio Conferencing".
• Select it and click Buy or Get (it may show as $0.00 in some regions or have a small monthly fee).
• Choose the monthly plan and buy the number of licenses you need (you only need it for people who create meetings, usually just you or a few staff).
• Complete the purchase.

3.Assign the license

• Go to Users > Active users.
• Select yourself (or the user(s) who schedule meetings).
• Click Licenses and apps > turn on Audio Conferencing > Save changes.
• Wait 5-60 minutes (sometimes up to a few hours) for the change to activate.

4.Test it

• Create a new Teams meeting in Outlook or the Teams app.
• The invite should now automatically include a dial-in phone number (usually a toll number for your country) and a Conference ID.

Notes

• Only the meeting organizer needs the Audio Conferencing license. Attendees can dial in for free.
• Once enabled, every new meeting will include the dial-in info automatically.
• Existing meetings won’t update, you’ll need to create new ones.

If the issue persists after enabling the add‑on, or if you’re unable to locate it, I recommend creating a service request with Microsoft Support for further assistance. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin.

I hope this information is helpful and provides a clear path forward. If you have any further questions or need additional assistance, please feel free to reply in the comments. I’m always happy to help. Wishing you a wonderful day.

Dial‑in phone numbers are only added to Teams meeting invites when Audio Conferencing (PSTN conferencing) is correctly set up and licensed for the tenant and for the users who schedule meetings.

From the described behavior (no dial‑in details on any meeting from anyone in the company, and no option visible), the environment is missing working Audio Conferencing/PSTN conferencing:

1. Dial‑in details are added automatically only when:
   • The meeting is scheduled from Outlook using the Teams add‑in, or directly from Teams, and
   • PSTN/Audio Conferencing is turned on and licensed for the organizer’s account. When this is in place, the invite automatically includes a phone number and conference ID.
2. If no dial‑in number appears at all:
   • The Audio Conferencing feature may not be configured by the tenant admin, or
   • The correct Audio Conferencing licenses have not been purchased or assigned to the users who schedule meetings.
3. To get dial‑in working for the organization, the tenant admin must:
   • Purchase and assign the appropriate Audio Conferencing (Teams Phone/Audio Conferencing) licenses to the users who will organize meetings.
   • Ensure Audio Conferencing is enabled for those users so that their meetings are associated with a conferencing bridge and dial‑in numbers.
   • After that, when those users schedule a Teams meeting (from Outlook or Teams) and send the invite to at least one recipient, the invite will include:
     • A dial‑in phone number, and
     • A conference ID, plus the standard “Join” link.
4. If a dial‑in number is still not available after licensing and configuration:
   • The feature is still not configured correctly at the tenant level, or
   • The license assignment is incomplete or incorrect for the organizer. In that case, the admin must review Audio Conferencing setup and licensing for the tenant.

There is no way to add a PSTN dial‑in option to Teams meetings without the proper Audio Conferencing/PSTN licensing and configuration on the Microsoft 365 tenant.
