Calling Plans are an add-on telephone service that, when combined with Phone System in Office 365, allow users to make and receive phone calls outside of the organization.  The Calling Plan provides dedicated phone numbers for licensed users.  These users can make voice calls from all Skype for Business clients, including the PC application, mobile devices, and certain desk phones enabled with Skype for Business.  Calling Plans, when combined with other features of the Office 365 Phone System such as Auto-Attendants and Queues, can become the all-inclusive phone system for an entire organization.


There are two available Calling Plan options: Domestic, and Domestic and International.  In the U.S., both Plans offer 3000 minutes for Domestic calls and the Domestic and International plan also includes 600 minutes for International Calls.  Please contact our Support Team for details on other regions or on Communication Credits if more minutes are required.



Getting Started


To get started with setting up a Calling Plan for a user, the following will be needed:

  • An Enterprise E5 license or an Enterprise E3 license with the Phone System add-on assigned to the user.
  • A Domestic Calling Plan or Domestic and International Calling Plan license.
  • A user with Global Administrator or Skype for Business Administrator roles assigned.


Please contact our Support Team to request the Phone System add-on or Calling Plan licenses.  We will soon be adding these licenses to our Control Panel to allow fully self-service orders.
