Microsoft 365 business Voice works within Microsoft Teams…

…so if you have less than 300 people and one of the following Microsoft 365 subscriptions, then it could work for you:

  • Microsoft 365 Business
  • Microsoft 365 E3
  • Microsoft 365 A3
  • Microsoft 365 A1
  • Office 365 F1
  • Office 365 E3
  • Office 365 E1
  • Office 365 Business Premium
  • Office 365 Business Essentials


In order to use Microsoft 365 Business Voice you will need to transfer your existing phone numbers to Microsoft. Once you’ve done that, you can build a calling plan to fit your business, but as standard UK users receive 1,200 minutes of domestic calls per user.

Business Voice can be used with Yealink handsets, Jabra Headsets, your laptop or even your mobile phone.


Although 365 Business Voice will manage functionality such as welcome messages, auto attendants, call queues, hunt groups and voicemail, it’s worth noting that complex phone set ups can be a challenge. If you have complex hunt groups, multi-level auto attendants or any very specific functionality then you will either have to make some compromises or stick with a more advanced phone system.

Having said that, the savings that can be made by moving to 365 Business Voice are significant, so it’s worth considering if some of your processes can be changed to meet its functionality.

How do I get started?

Like any new phone system installation, you will need to talk to us to discuss your requirements. We can check your current licencing, help to design your phone system set up and then carry out any installation work required.
