Microsoft Teams Phones: Configure line keys in Teams admin center for streamlined device management

Microsoft Teams admin center will allow IT admins to configure line keys on Teams-certified phones starting mid-July 2025. This feature supports personal and common area phones, enhancing setup and management. Admins can use device-agnostic configurations or model-specific templates. No action is required before the rollout. We’re introducing a new capability in the Microsoft Teams admin center (TAC) that allows IT admins to configure line keys on Microsoft Teams-certified phone devices. This enhancement simplifies setup and management by enabling assignment of line keys to contact types such as speed dials, call queues, and shared lines—supporting both personal and common area phone (CAP) scenarios. This message is associated with Microsoft 365 Roadmap ID 493320. When this will happen: General Availability (Worldwide, GCC): We will begin rolling out mid-July 2025 and expect to complete by late July 2025. General Availability (GCC High): We will begin rolling out mid-September 2025 and expect to complete by late September 2025. General Availability (DoD): We will begin rolling out mid-November 2025 and expect to complete by late November 2025. How this will affect your organization: After this rollout, admins can assign line keys in the Teams admin center in two ways: Using a generic configuration section (device-agnostic) Using device model-specific templates Important: For common area phones, line key assignment will be managed exclusively through the Teams admin center.
