Extend Microsoft Teams with cloud-based telephone capabilities and Calling Plan service for users assigned to Country Zone 1 in the UK and Canada. Teams Phone provides the telephony layer for calling through Teams, while Calling Plan connects eligible users to public switched telephone network calling. The service is an entitlement rather than a physical handset, desk phone, gateway, or appliance. Microsoft 763B5A0DC391 combines Teams Phone with Calling Plan under the Country Zone 1 service designation. It fits organizations standardizing user calling in Microsoft Teams and requiring calling coverage associated with the UK and Canada zone. Administrators assign the service to the intended users through their Microsoft tenant and manage calling configuration within the organization’s Teams telephony environment. This offering differs from a hardware phone purchase because it supplies cloud calling rights, not an endpoint device. It also combines the Teams Phone capability and Calling Plan component in one service offer, rather than providing only a calling client or only a physical desk-phone connection. Confirm that assigned users have the required Microsoft Teams environment and that the selected country zone aligns with the users and calling locations being served.
