Microsoft Teams Calling: What You Need to Enable PSTN

Many businesses already live in Microsoft Teams for chat and meetings \xE2\x80\x94 so using it as the phone system seems obvious. It can be great, but enabling real phone calls (PSTN) takes a deliberate choice.

Teams Out of the Box Can't Call Phones

Standard Teams handles internal calls and meetings, but to dial and receive regular phone numbers (the PSTN \xE2\x80\x94 public switched telephone network) you need to add calling capability. There are two main paths.

Option 1: Microsoft Calling Plans

You buy phone numbers and minutes directly from Microsoft as an add-on. Simplest to set up, but pricing and international coverage can be limiting, and you're locked to Microsoft's rates.

Option 2: Direct Routing / Operator Connect
