Why it shows up like this
Unreviewed registry note: Seeing MSFT* TEAMS PHONE SYS on your billing statement means you or your organization was billed by Microsoft Corporation for cloud-based telecommunication services. This descriptor represents Microsoft Teams Phone System, domestic or international calling plans, or business voice add-on licenses associated with Microsoft 365 enterprise accounts. Monthly per-user fees typically range from eight to fifteen dollars depending on the selected calling bundle.
Unreviewed registry note: These charges appear when a company administrator adds cloud telephony features to user profiles, when automated communication credits reload after dipping below minimum thresholds, or when an annual business subscription auto-renews. Because enterprise IT departments manage tenant billing, individual employees rarely see these charges directly unless they manage their own business subscription or have linked personal payment methods to an admin center.
