Turn Microsoft Teams into a Full Business Phone System
If your organization already uses Microsoft Teams, here’s something worth checking out — you can actually make and receive traditional phone calls (PSTN) directly inside Teams. No extra desk phones, no complex PBX setup — just Teams handling everything.
Setting up PSTN calling is simpler than it sounds. You can go with a Microsoft Calling Plan, Operator Connect, or a Direct Routing setup depending on your organization’s size and existing phone system. Once configured, Teams becomes a complete calling platform — from Caller ID and number assignments to emergency calling, call queues, and auto attendants.
It’s a great option if you’re planning to streamline communication for remote or hybrid teams, or want to move away from legacy telephony systems altogether.
We’ve put together a clear, step-by-step guide that covers everything you need — from required licenses to full PSTN configuration for teams and testing.
