Microsoft 365 Phone System License
This annual license activates Microsoft 365 Phone System capabilities for your organisation's tenant. It provides the core software entitlement required to enable cloud-based calling features within the Microsoft 365 environment. The license is delivered digitally and requires a valid Tenant ID for provisioning. Order processing begins after Tenant ID verification.
Suited for Microsoft 365 tenants adding PSTN
Organisations already using Microsoft 365 who need to replace on-premises PBX hardware with a cloud voice solution will find this license fits their deployment model. It is not intended for standalone telephony platforms or environments that do not use Microsoft 365 identity services. Buyers without an existing or planned Microsoft 365 tenant cannot apply this entitlement.
Annual term with tenant-scoped entitlement
The license covers a 365-day period from activation and applies to the specific tenant identified during order processing. It unlocks Phone System features for assigned users within that tenant boundary. Capacity scales with the number of licenses assigned to users. Organisations requiring multi-tenant management must secure separate licenses for each distinct tenant ID.
