This article provides guidance on how to make calls using Microsoft Teams Voice for both university numbers and external phone numbers.

Note: Illinois State University will begin cutting some departments over to Microsoft Teams Voice for phone services beginning in July 2026. If your area has not yet been cut over to this service, you will not be able to call outside the University using Microsoft Teams. If you are unsure if you have been cut over to Microsoft Teams Voice, please reach out to the Technology Support Center (contact information below).

How to make a call in Microsoft Teams

1. Select Calls in Microsoft Teams.
