Our Verdict

Microsoft Teams Phone makes the most sense when Teams is already where people chat, meet, share files, and manage identity. It can reduce tool sprawl because calling, voicemail, queues, auto attendants, devices, and admin work sit inside the Microsoft environment.

Before subscribing, test the exact calling plan, porting process, emergency calling setup, desk phones, call queues, and support options. Companies that want a standalone phone vendor with simpler pricing, built-in SMS, or contact-center tools may prefer a dedicated phone-system provider.

A good fit if you

  • Microsoft 365 companies moving phone service into Teams.
  • IT teams that want calling managed through Microsoft admin tools.
  • Hybrid teams that already use Teams meetings and chat every day.
  • Organizations that need PSTN options through Microsoft or approved carriers.

Look elsewhere if you

  • Teams that do not use Microsoft 365.
  • Small companies that want a phone app with very simple seat pricing.
  • Sales teams that need heavy SMS and CRM-first call logging.
  • Contact centers that need deep native routing and workforce tools.
  • Companies that want phone-specific user reviews rather than broader Teams feedback.
Next step: write down the problem you need solved, check the pricing details, test one real workflow, then compare alternatives before you pay.

What Is Microsoft Teams VoIP Software?

Microsoft Teams VoIP Software refers to Teams Phone, the Microsoft cloud calling system that adds PSTN calling, call queues, auto attendants, voicemail, devices, and phone administration to Microsoft Teams.

It fits companies already running Microsoft 365 and Teams who want phone service to sit in the same admin, identity, security, and daily collaboration environment.

Microsoft Teams VoIP Software Pros and Cons

Pros

  • Native Teams calling — Users can make and receive calls in the same Teams app they already use for meetings and chat.
  • Flexible PSTN paths — Companies can use Microsoft Calling Plans, Operator Connect, Direct Routing, or Teams Phone Mobile depending on country and carrier needs.
  • Call queues and attendants — Core business phone routing features are part of the Teams Phone story.
  • Teams Phone Standard — Add cloud phone system features to Teams users.
  • Calling plans and PSTN options — Use Microsoft calling plans, Operator Connect, Direct Routing, or mobile operator options.

Cons

  • SMS is not the main workflow — Teams Phone is better for voice calling than for sales-style texting workflows.
  • Setup needs telecom planning — Porting, emergency locations, SBCs, carriers, and call routing should be mapped before rollout.
  • Support may involve multiple vendors — Companies may need Microsoft support, a carrier, or a managed partner depending on the deployment model.
  • Poor fit outside Microsoft 365 — Teams that do not use Microsoft 365.
  • Weak fit for heavy SMS workflows — Sales teams that need heavy SMS and CRM-first call logging.

Integrations

Teams Phone integration value mostly comes from Microsoft 365 rather than a long marketplace list. Check Entra ID, Teams admin policies, Outlook contacts, devices, Dynamics or contact-center connectors, compliance recording, carriers, and any CRM call-logging workflow before switching numbers.

Getting Started: What Implementation Actually Takes

Start with a call-flow map, not the pricing page. List departments, main numbers, queues, emergency locations, porting needs, desk phones, shared devices, and carrier requirements. Then run a small pilot with real users before moving important customer-facing numbers.

What works well

  • Users like that Teams keeps chat, meetings, files, and Microsoft 365 work in one familiar place.
  • For phone use, it works best when staff already use Teams every day and IT already manages Microsoft identity, policies, and devices.

What gets frustrating

  • Reviewers often complain about clutter, login friction, notifications, search, and performance when Teams becomes too busy.
  • Teams Phone still needs careful planning around licenses, carriers, emergency calling, call routing, recording, and retention.
MAQTOOB take: Treat the broad Teams reviews as collaboration context, not a phone-only verdict. Test the calling workflow, admin controls, and recording rules before replacing a dedicated phone system.
