Microsoft Teams Phone Resource Account licenses
In Microsoft Teams, all auto attendants and call queues require an associated resource account. Each resource account must be assigned a Microsoft Teams Phone Resource Account license to ensure they're correctly identified by the system and properly function, regardless of whether the resource account will be assigned a telephone number.
Organizations with a subscription that includes Teams Phone are allocated a certain amount of Teams Phone Resource Account licenses at no extra cost. A Microsoft calling plan isn't required unless you want to be able to dial out using that resource account. For more information, see Plan for Teams auto attendant and call queues.
The Teams Phone Resource Account license should never be assigned to users that aren't resource accounts.
Note
All resource accounts must be assigned a Teams Phone Resource Account license, regardless of whether they'll be assigned a phone number or not.
If you're currently using resource accounts that aren't assigned any license, you should revisit them to ensure they're assigned a Teams Phone Resource Account license.
Don't assign a Teams Phone Standard license to a resource account. If you currently have resource accounts configured with Teams Phone Standard licenses, you must switch to a Teams Phone Resource Account license as described below.
Resource Account license allocation
Your organization is allotted Teams Phone Resource Account licenses based on its overall size. Any organization that has a subscription with Phone System features, such as Teams Phone Standard, Teams Phone with Calling Plan, and Teams Shared Devices licenses, is allocated 25 Teams Phone Resource Account licenses available at no cost.
For every 10 user licenses of Teams Phone Standard, Teams Phone with Calling Plan, or devices with Teams Shared Devices license in your organization, one more Teams Phone Resource Account license becomes available. Most organizations will have enough Teams Phone Resource Account licenses based on this scaling plan.
In the event more Teams Phone Resource Account licenses are required, you can purchase more Teams Phone Resource Account licenses beyond the standard allocation through EA, EAS, EES, CSP, Web Direct, MCA – Customer led, and MCA – Partner led or your Microsoft account representative at a cost.
Your allocation of Teams Phone Resource Account licenses is not automatically added to your tenant. You will need to go through the purchasing process for Teams Phone Resource Account licenses. Licenses within your allocation of Teams Phone Resource Account licenses will be zero cost. Any Teams Phone Resource Account license that exceeds your allocation of licenses will have a cost.
License allocation example
Contoso, Inc. purchased 500 licenses that include Phone System (one for each employee) and has 100 devices licensed with the Teams Shared Devices license. Contoso is allotted an initial 25 plus 60 Teams Phone Resource Account licenses, 85 in total. Their organization has 90 call queues and auto attendants. They need to assign all the Teams Phone Resource Account licenses and purchase five extra Teams Phone Resource Account licenses.
How to obtain Microsoft Teams Phone Resource Account licenses
You obtain Teams Phone Resource Account licenses from the same purchasing channel you purchased the subscription containing Teams Phone. For example, if you purchased Resource Account licenses through an Enterprise Agreement (EA), you need to order through EA.

Change an existing resource account to use a Microsoft Teams Phone Resource Account license
If you have existing resource accounts using a Teams Phone Standard license, you must switch to using to a Teams Phone Resource Account license:
- Purchase the new Teams Phone Resource Account license.
- Follow the linked steps in the Microsoft 365 admin center to Move users to a different subscription.
Warning
Always remove a Teams Phone Standard license and assign the Teams Phone Resource Account license in the same license activity. If you remove the old license, save the account changes, add the new license, and save the account settings again, the resource account may no longer function as expected, like your organization's auto attendants and call queues not working anymore.
If this happens, we recommend you create a new resource account using the Teams Phone Resource Account license and remove the broken resource account.
