The short answer
A charge from MSFT* TEAMS PHONE SYS corresponds to Microsoft Teams Phone System, PSTN Calling Plans, or Microsoft 365 Voice add-ons from Microsoft Corporation.
Why it shows up like this
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.
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.
To review detailed invoices or stop recurring charges, sign in to the Microsoft 365 Admin Center using an administrator account. Navigate to the billing section to inspect active products, view assigned phone numbers, and cancel unneeded voice licenses before the next billing cycle begins. If you cannot identify the administrator or suspect billing errors, reach out to Microsoft commercial support or dispute the charge with your financial institution.
