Assessment Reasoning
The update changes the rollout timeline for a new Teams Phone call history layout that adds tabs for each multi-line account. The feature rollout now starts in early November instead of early October, indicating only a minor schedule change. Admins mainly need to update support materials and notify teams managing multi-line setups. User experience changes are noticeable for multi-line users but require no configuration or downtime.
