(Updated) Microsoft Teams: Multi-line call history tabs in the Calls app

Updated October 6, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Teams is introducing a redesigned call history experience for Teams Phone users who have multi-line calling enabled. Call activity, including call history, voicemails, and recordings, will be organized by phone line in dedicated tabs within the Calls app.

This change simplifies navigation for users who manage multiple phone lines.
