Microsoft Teams add-on licenses

What are add-on licenses?

Add-on licenses are licenses for specific Microsoft Teams features. They give you the flexibility to add features only for users in your organization who need them. To add a feature, buy one add-on license for each user who will use it.

What features can I get with add-on licenses?

Here's a list of features that you can add with Teams add-on licenses. The add-on licensing options available to you depend on the Microsoft 365 or Office 365 plan you have.

Feature
Description
Small business (<300 users) Large business (>300 users)
Microsoft 365 Business Voice

1 If you're a small or medium-sized business who has a Microsoft 365 Enterprise plan, you can still buy add-on licenses for these voice features, however, we recommend that you consider a Microsoft 365 Business plan and Business Voice.

What voice features are available with my plan?

See what add-on licenses you need to get voice features in Teams, depending on the plan you have.

Depending on the voice features that you want, we recommend comparing whether it's more cost effective for you to switch to a plan that includes those features. For example, for most large organizations, buying a bundle of software in a Microsoft 365 Enterprise plan will result in lower overall cost. Typically, when you buy several add-on licenses individually instead of as part of a plan, you may end up with a higher combined cost.

If you're a small or medium-sized business (less than 300 users), you have four ways to get voice features:

  • Buy a Microsoft 365 Business plan and Microsoft 365 Business Voice.
  • Buy an Enterprise E1 or E3 plan and Microsoft 365 Business Voice.
  • Buy an Enterprise E1 or E3 plan and add voice features individually.
  • Buy an Enterprise E5 plan, which includes voice features.

For Microsoft 365 Business Voice, you have two options to choose from:

  • Microsoft 365 Business Voice with a Calling Plan: Get this if you want all phone number management and billing to be handled by Microsoft.
  • Microsoft 365 Business Voice without a Calling Plan (Direct Routing): Get this if you want all phone number management and billing to be handled by your third-party telephone provider. You'll need to set up and deploy Direct Routing to connect your on-premises Session Border Controllers (SBCs) to Microsoft 365 or Office 365.

To learn more, see What do I need to buy to use Microsoft 365 Business Voice?.

Here's a summary, based on licensing plan.

Small business plan options

If Audio Conferencing isn't supported in your country or region, you have the option to get a Microsoft 365 Enterprise E5 without Audio Conferencing plan or an Office 365 Enterprise E5 without Audio Conferencing plan.

If you already have a Microsoft 365 Enterprise or Office 365 Enterprise plan, you can still buy add-on licenses for individual voice features. However, you have the option to switch to a Microsoft 365 Business plan and Microsoft 365 Business Voice. In some cases, depending on the features that you want, it might be more cost effective to get a Microsoft 365 Business plan with Microsoft 365 Business Voice.

Note

If you need to use a third-party telephone service, Direct Routing is deployed in your organization, or if Calling Plans aren't available in your country or region, you need to use Direct Routing for voice features.
