Microsoft Teams Phone vs Zoom Phone 2026: Advisor Verdict
By the Best Business Technology Advisory Team. Updated July 2026.
Microsoft Teams
UCaaS & Business Voice
The default answer for Microsoft 365 shops; the work is in making it a real phone system.
Best for: Microsoft 365 standardized companies
Teams Phone is less a competitor in the UCaaS market than the gravity well the whole market now orbits. For a company standardized on Microsoft 365, the license economics are compelling: Teams Phone is a modest add on, included outright in E5, and users never leave the application they already spend their day in. Identity, security, and administration stay inside the Microsoft estate, which IT departments value highly. The honest tradeoffs: calling features are serviceable rather than category leading, sophisticated routing and reception scenarios take more work than on dedicated platforms, and making Teams a reliable business phone system requires carrier decisions, calling plans, Operator Connect, or direct routing, that Microsoft leaves to the buyer. Support for voice problems runs through general Microsoft channels unless a partner fills the gap, which is why a large share of successful Teams voice deployments involve a voice enablement specialist. The right comparison is rarely Teams versus nothing; it is Teams plus enablement versus a dedicated platform, priced honestly on both sides.
Zoom
UCaaS & Business Voice
The value pick: serious telephony at aggressive prices, with AI included.
Best for: meetings first organizations
Zoom's phone business grew out of its meetings dominance, and that origin still shapes who it fits best: organizations that already run on Zoom meetings and want telephony that simply joins the platform they know. Zoom Phone is a genuinely capable cloud phone system, deployment is among the fastest in the category, and the pricing is the most aggressive of any major provider, especially in Workplace bundles where phone, meetings, whiteboard, and the AI Companion assistant land at a price rivals struggle to match. Including AI features in the base price rather than as a paid add on has aged well as competitors monetized theirs. The honest limits: phone feature depth trails the longest tenured platforms, and complex multi site telephony, intricate call routing, or heavy compliance requirements can outgrow it. For the large population of businesses whose phone needs are real but not exotic, Zoom's combination of price, simplicity, and a user experience employees already like is hard to argue with.
Advisor Verdict
This is the platform gravity matchup: both vendors are betting you will buy phones from whichever app your company already lives in. The right answer usually follows that bet. A Microsoft 365 shop has to take Teams Phone seriously because the license math is compelling; a company that runs its day on Zoom meetings gets the same logic in the other direction, plus a phone product that is easier to stand up.
| Provider | List price | Sweet spot | Standout |
|---|---|---|---|
| Microsoft Teams Phone | $8 to $15 /user/mo add on | Microsoft 365 shops | License economics |
| Zoom | $10 to $20 /user/mo | Meetings first teams | Value with AI included |
Choose Microsoft Teams Phone when
- Your staff already spend the workday in Teams and you run Microsoft 365
- You hold E5 licensing, where Teams Phone is already included
- One vendor, one identity platform, and one admin plane outweigh calling feature depth
- You are prepared to make carrier and enablement decisions, or bring a voice partner to make them
Choose Zoom Phone when
- Your organization is meetings first and those meetings run on Zoom
- You want phones live in days with AI transcription and summaries included
- Calling features and admin simplicity matter more than deep Microsoft integration
- You want a lower list price without giving up a credible platform
The pricing reality
Teams Phone lists at about $8 per user per month as an add on, $15 with a domestic calling plan, and is included in E5; the real cost hides in calling plans, carrier routing, and enablement work Microsoft leaves to you. Zoom Phone lists at about $10 to $20 standalone and drops inside Workplace bundles. On paper Teams is cheaper for Microsoft shops; in practice the gap narrows once the voice project is priced honestly.
The verdict by use case: committed Microsoft 365 organizations, especially on E5, should start with Teams Phone and budget for proper voice enablement; Zoom first organizations, and anyone who wants capable phones without a telephony project, should start with Zoom.
