Microsoft Teams Phone International Calling Plan is an add-on for organizations using Microsoft 365 Enterprise Voice. It provides a bundle of international outbound calling minutes per user, enabling users to place calls to numbers in supported countries directly from Teams across devices. The plan integrates with Teams Phone features like call transfer, voicemail, call queues, and emergency calling where available. Administrators gain centralized number management, reporting, and policy controls through the Teams admin center. This add-on requires Teams Phone (or equivalent Enterprise Voice licensing) and availability varies by region and carrier infrastructure. It’s ideal for globally distributed teams seeking a predictable, compliant calling solution with Microsoft-managed PSTN connectivity and consolidated billing within the Microsoft 365 ecosystem.
