This functionality is currently still under development, but you can sign up at and Microsoft will notify you once they are ready to on-board you.

Qualification for being in the preview:

  • You need an Office 365 billing address in one of the countries where PSTN Calling is available (tech preview or GA) – If you don’t have this you cannot go on to purchase a license.

Then to license end users:

  • The O365 service location profile country of the user must match the country of the phone number being provided.
  • You need to be able to provide a physical address for the user+phone number that is allowed by the national regulator – This varies between countries. In UK any UK address is allowed, but in France, addresses must be within a geographical zone within the country defined by the regulator.

Requirements for preview

  • 50 users using PSTN Calling with their Office 365 number as their main telephone number
  • Users are expected to complete frequent program surveys to provide feedback on experiences
  • Join occasional live feedback sessions and actively provide feedback
