How To Articles

Recently, there has been a significant focus on connecting a carrier to Microsoft Teams. With years of experience in the telecommunications sector, I can assure you that this integration can significantly enhance communication and collaboration for companies. This piece will walk you through the process of interconnecting a carrier to Microsoft Teams with step-by-step instructions.

Step 1: Understand the Benefits

Before diving into the technical details, it’s important to understand why this integration is valuable. By connecting your carrier to Microsoft Teams, you can leverage the power of both platforms. Microsoft Teams provides a comprehensive collaboration suite, including chat, video meetings, file sharing, and more. On the other hand, carriers offer robust calling capabilities and phone numbers, which can be seamlessly integrated into Teams.

By bringing these two together, you can have a unified communication platform that combines the best of both worlds. Employees can make and receive calls directly within Teams, eliminating the need for separate phone systems. This integration can improve productivity, simplify workflows, and enhance the overall communication experience.

Step 2: Choose a Carrier

The first step in interconnecting a carrier to Microsoft Teams is selecting a carrier that supports this integration. Not all carriers offer this feature, so it’s essential to do your research and choose a carrier that aligns with your organization’s needs and requirements.

Look for carriers that explicitly mention their compatibility with Microsoft Teams or provide integration documentation. Additionally, consider factors such as pricing, call quality, customer support, and any additional features that may be important to your business.

Step 3: Configure Direct Routing

Once you have chosen a compatible carrier, the next step is to configure Direct Routing. Direct Routing is a feature in Microsoft Teams that allows you to connect external telephony providers, such as your chosen carrier, to Teams.

Set up Direct Routing by following the documentation provided by Microsoft. This typically involves configuring a Session Border Controller (SBC) that acts as the intermediary between your carrier and Teams. The SBC ensures that calls are routed correctly and that all necessary protocols are supported.

Step 4: Provision Phone Numbers

After configuring Direct Routing, you will need to provision phone numbers from your carrier. Depending on your carrier’s process, this may involve requesting numbers and assigning them to specific users or departments within Teams.

Make sure to communicate with your carrier and understand their provisioning process. They will guide you on how to order and assign phone numbers effectively.

Step 5: Test and Troubleshoot

Once you have completed the configuration and provisioning steps, it’s crucial to thoroughly test the integration and address any issues that may arise. Test both inbound and outbound calls to ensure that everything is working as expected.

If you encounter any problems during the testing phase, reach out to your carrier’s support team for assistance. They should be able to help you troubleshoot and resolve any issues that may arise.


Interconnecting a carrier to Microsoft Teams can revolutionize the way your organization communicates. By leveraging the combined power of Teams and carrier services, you can create a seamless and efficient communication platform. Whether it’s making and receiving calls or collaborating on projects, this integration has the potential to enhance productivity and streamline workflows.

Remember to carefully choose a compatible carrier, configure Direct Routing, provision phone numbers, and thoroughly test the integration. By following these steps, you’ll be well on your way to interconnecting your carrier to Microsoft Teams and reaping the benefits of unified communication.
