Add Microsoft cloud voice capability without bundling a Calling Plan. Microsoft 365 Business Voice Standard is a subscription service for organizations that require the Business Voice offer while keeping calling connectivity separate. It fits Microsoft 365 voice environments where the selected service scope must explicitly exclude a bundled calling plan. This configuration is not a desk phone, gateway, handset, or physical appliance. The without-calling-plan designation is the key distinction when comparing Business Voice service options. It identifies an edition that supplies the Business Voice service package but does not include Calling Plan service. That separation supports environments where calling connectivity is selected independently rather than included in the Business Voice subscription. As a cloud-service entitlement, it has no installed hardware footprint or equipment dimensions. CC69A07C-8C51-457F-BB2A-F21A62D6BEDE denotes the Standard Business Voice subscription without Calling Plan. Select this service when Business Voice Standard is required and a bundled Calling Plan is not part of the intended voice configuration. Its defining scope is Business Voice without bundled calling service, distinguishing it from hardware voice endpoints and service packages that include calling connectivity.
