Turn Microsoft Teams Into a Fully-Featured Business Phone System
Seamlessly add enterprise calling to Teams with the provider of your choice—guided by your trusted advisor.
What Is Teams Voice Enablement, and Why It Matters
More than chat and meetings. Teams can be your complete voice solution.
If your organization already uses Microsoft Teams for collaboration, why manage a separate phone system? With Direct Routing or Operator Connect, you can add entire business calling to Teams, turning it into a complete cloud-based communications platform.
At TeleSwitch, we help you select the best-fit voice provider, architect the proper call flow, and ensure compliance and call quality—without pushing any specific carrier or vendor. Whether you're replacing a PBX or simplifying IT, we guide the entire process from planning to deployment.

The Strategic Value of Expert Guidance
Enabling voice in MS Teams is simple but not always straightforward.
Direct Routing, Operator Connect, and Microsoft Calling Plans all support Teams voice—but they vary in features, pricing, and flexibility. Choosing the wrong model can lead to additional expenses, call quality issues, porting delays, or licensing misalignment.

Frequently Asked Questions
Here’s what decision-makers need to know before enabling voice in Teams.
What’s the difference between Direct Routing, Operator Connect, and Calling Plans?
Direct routing gives you the most flexibility regarding your choice of provider. Operator Connect is more straightforward but less customizable. Microsoft Calling Plans are typically selected for small teams. We help you choose based on your needs.
Can we keep our phone numbers?
Yes. Number porting is supported, and we guide you through the process with minimal disruption.
What’s required to enable Teams calling?
You’ll need the right Microsoft licensing (like E5 or a voice add-on) and a certified Direct Routing or Operator Connect provider. We help with both.
Will this work for remote or mobile employees?
Absolutely. Teams voice works across desktop, mobile, and web—giving your users full calling functionality wherever they are.
Can this replace our entire phone system?
Yes. With the proper configuration, Microsoft Teams can become your complete cloud phone system, integrated with meetings, messaging, and collaboration.
