help Microsoft Teams Phone System FAQ

Do I need a third-party VoIP provider to make external calls with Microsoft Teams Phone System?

Not necessarily. If you use Microsoft's Calling Plan, Microsoft acts as your telephone carrier and provides the PSTN (Public Switched Telephone Network) connectivity directly. Alternatively, you can use your own carrier via Direct Routing.

What is the difference between Microsoft Teams Phone System and Skype for Business?

Microsoft Teams Phone System is the direct successor to Skype for Business, which Microsoft officially retired in 2021. The Teams Phone System integrates deeply with SharePoint, Outlook, and the broader Microsoft 365 ecosystem.

Can I port my existing business phone numbers to Microsoft Teams Phone?

Yes, Microsoft supports number porting so you can bring your existing local and toll-free business numbers into the Teams environment. This process is coordinated through your Microsoft 365 admin center and your chosen carrier.

Does Microsoft Teams Phone System require an internet connection to function?

Yes, because it is a Voice over IP (VoIP) system, an active internet connection is required to make or receive calls. If your office network goes down, your phones will also go down unless you have cellular failover.
