Microsoft Teams: Use multiple phone lines on Teams mobile

Microsoft Teams Phone will support multiple phone lines on the Teams mobile app starting late July 2026. Users can manage and select assigned numbers for calls, view unified call history, and handle calls across lines on iOS and Android. No action is required; admins may review user assignments post-rollout. What and Why We are expanding Microsoft Teams Phone capabilities to mobile devices by enabling users to manage and use multiple assigned phone numbers directly within the Teams mobile app. Users will see and manage their assigned phone lines in the Calls app on Teams mobile, allowing them to choose the appropriate number when placing or returning calls. This update provides a more consistent calling experience across devices and helps users who manage multiple roles or regions stay productive without switching devices or workflows.
