Teams Phone user multi‑line gives callers more flexibility and control by allowing administrators to assign up to 10 phone numbers to a single user. With full support on Teams devices, users can seamlessly make and receive calls from multiple numbers without switching accounts or hardware. This makes it easy to manage different roles, departments, or regional identities—all from one unified Teams experience. The result is a familiar, localized calling experience for users who work across diverse markets or with global customers.
