[Introduction]
Teams Phone user multi-line provides greater flexibility for organizations whose users manage multiple business numbers. This capability allows administrators to assign up to 10 telephone numbers to a single Teams Phone user, all within one Teams account. Users can make and receive calls from multiple numbers across Teams desktop, Teams mobile, and Teams devices without switching accounts or hardware. This enhancement supports a familiar and localized calling experience for users who work across regions, roles, or business lines.
This capability supports scenarios such as:
Establishing local presence across multiple regions
Supporting users with multiple roles or responsibilities
Allowing executives, assistants, or support teams to manage multiple business lines within one Teams account
This message applies to Teams for Windows desktop, Teams for Mac desktop, and Teams for the web. It is associated with Microsoft 365 Roadmap ID 557716.
[When this will happen:]
Targeted Release: We will begin rolling out in early April 2026 and expect to complete by late April 2026.
General Availability (Worldwide): We will begin rolling out in late April 2026 and expect to complete by mid-May 2026.
