What Microsoft 365 licenses are required before deploying Operator Connect?

A Microsoft 365 subscription that includes both Microsoft Teams and Teams Phone is required before deploying Operator Connect. Teams Phone is the specific license component that enables PSTN calling capabilities within Teams, and it must be active in the tenant before any Operator Connect carrier can provision numbers.

Microsoft 365 E5 includes Teams Phone in the base license, so E5 customers can proceed directly to carrier setup. Microsoft 365 E3 does not include Teams Phone, which means E3 customers must purchase the Teams Phone add-on separately before activating Operator Connect. Microsoft 365 Business Voice also includes Teams Phone. A standalone Teams Phone license is available as an add-on for other Microsoft 365 plans that do not include it by default. Beyond licensing, the organization needs a domain name verified by both Microsoft and the Operator Connect carrier, and a Teams Admin account with Global Admin or Teams Service Admin permissions to complete the configuration in the Teams Admin Center.
