Microsoft Teams Voice: Business Voice vs. Enterprise Voice – Tech Tip for November 2, 2021


TechWise Group has recently been fielding lots of questions about Microsoft Teams Voice. With so many of our customers continuing to work remotely or in a hybrid scenario, having a cloud-based calling solution has become critical. To this end, we’re going to take another look at Microsoft Teams Voice. To get started, let’s review some of the differences between Microsoft 365 Business Voice and Enterprise Voice.

Features of Microsoft 365 Business Voice and Enterprise Voice

Microsoft 365 Business Voice and Enterprise Voice in Microsoft Teams provide the same services to both small business and Enterprise users. Both services provide cloud-based phone systems with Phone System, domestic and international calling options, and audio conferencing. Both services offer:

  • Phone System
  • Caller ID
  • Voice Mail
  • Call Menus
  • Shared Phone Lines
  • Emergency Calling
  • Domestic Calling
  • Free calls within country or region
  • International plans available
  • Toll-free dialing available
  • Audio Conferencing
  • Host conference calls with non-Teams users
  • Host conference calls with non-Internet users
  • What’s the difference between Business Voice and Enterprise Voice?

Difference Between Microsoft 365 Business Voice and Enterprise Voice

While Business Voice and Enterprise Voice offer the same services, there are a few important differences:

  • Maximum number of licenses - You can purchase up to 300 Business Voice licenses. With Enterprise Voice, you can purchase an unlimited number of licenses.
  • Simplicity - Business Voice gives you everything you need to get Phone System up and running; you don’t need to worry about which licenses each user needs. With Enterprise Voice, however, you can be more selective about which users are assigned licenses like audio conferencing.

Business Voice licenses are available for the first 300 users in your organization. If your organization grows beyond 300 users, you need to purchase Enterprise Voice licenses for those additional users. You don’t need to switch your original 300 users from Business Voice to Enterprise Voice. Both licenses can exist in an organization at the same time. However, only one license, either Business Voice or Enterprise Voice, can be assigned to an individual user. You can’t assign both licenses to a single user.
