Microsoft Teams Phone Review 2026

The default option for Microsoft 365 shops. A strong cost story when the licensing math works out, but with real limitations that pure UCaaS platforms don't have. Here's the honest take.

Our view

Teams Phone is genuinely compelling for knowledge-worker organizations already on Microsoft 365. One app, one bill, no retraining. But it's not a one-size-fits-all answer, and we see a lot of companies get oversold on it. If you have a sales team doing heavy call volume, complex IVR, skills-based routing, or a contact center, Teams Phone will fight you. For everyone else on M365, it deserves a serious look.

What it costs in 2026

Teams Phone is an add-on to a Microsoft 365 base license. The total cost depends heavily on which M365 plan you're already on.

Teams Phone add-on
$10/user/mo
  • Requires M365 Business/E license
  • PSTN calling (via Calling Plan or Operator Connect)
  • Voicemail, auto attendant, call queues
  • No separate app, lives in Teams
E5 (bundled)
$57/user/mo
  • Teams Phone included at no extra charge
  • Domestic calling plan included
  • Advanced compliance & security
  • Best if you'd buy E5 anyway

Calling plans (domestic minutes) are a separate line item, typically $12–15/user/mo, or you can use Operator Connect via a carrier partner, which often delivers better rates and flexibility.

Don’t pay list price. Microsoft license pricing is fixed, but the calling side is not. Quoting Operator Connect through us typically lands 30%+ below Microsoft Calling Plan list rates.

Honest pros and cons

Strengths

  • One app for chat, video, calling, minimal change management
  • Compelling cost story for E5 customers (phone is already included)
  • Deeply embedded in M365 ecosystem (SharePoint, Outlook, etc.)
  • Strong compliance posture (FedRAMP, HIPAA, GCC High)
  • Microsoft AI (Copilot) integration roadmap is substantial

Weaknesses

  • Call routing and IVR significantly less flexible than purpose-built UCaaS
  • Contact center story is weak. Teams Contact Center requires third-party integration
  • Calling Plans are Microsoft-priced; Operator Connect adds flexibility but complexity
  • Cost advantage disappears for non-M365 shops or E1/E3 configs with add-ons
  • Mobile calling experience lags behind Zoom, Dialpad, and RingCentral

Who Teams Phone fits

Strong fit if you are…

  • A knowledge-worker organization already on M365 E3 or E5
  • On E5, phone is included and the math is almost always right
  • A government contractor or highly regulated org needing FedRAMP/GCC High
  • Looking to reduce app sprawl and consolidate onto one Microsoft-managed platform

Probably not a fit if you are…

  • Running a sales or support team with heavy call routing, queue management, or contact center needs
  • Not on Microsoft 365, there's no cost advantage without the bundling
  • Needing a high-quality mobile calling experience as a primary use case
  • On E1 or lower M365 licensing, the add-on math often loses to a standalone UCaaS platform
