Add domestic public switched telephone network calling capability for users located in the United States and Canada. This cloud calling entitlement extends a Microsoft 365 voice environment with domestic calling scope, allowing assigned users to place and receive calls using supported cloud voice workflows rather than relying solely on internal collaboration calls. Microsoft 117FE3B102C6 is the student-designated US and Canada Domestic Calling Plan. It is intended for education environments that require a separately assigned calling entitlement for eligible users. The plan addresses domestic calling geography across the United States and Canada; it is not a physical phone, gateway, headset, or on-premises voice appliance. Within the Microsoft Calling Plan family, this option is distinguished by its United States and Canada domestic coverage and student designation. Select it where the required service scope is domestic calling for student users, and where the organization’s cloud voice configuration requires a Calling Plan entitlement. Calling capacity, number assignment, user eligibility, and tenant voice configuration should align with the organization’s Microsoft 365 environment before service assignment.
