Microsoft Teams Direct Routing

A flexible and scalable way to enable external calling in Teams using your preferred telephony provider. Instead of relying solely on Microsoft’s Calling Plans, organizations can connect Teams to the PSTN through a certified Session Border Controller (SBC) and SIP trunks. This approach supports global coverage, cost optimization, and tailored integration with existing systems, making it ideal for businesses with complex communication needs or existing voice investments.

Global PSTN connectivity

Microsoft Teams Direct Routing connects Teams users to the traditional Public Switched Telephone Network (PSTN) through a certified Session Border Controller (SBC) and SIP trunk provider. For global enterprises, this allows centralized management of voice services across regions while ensuring local number availability and compliance with in-country regulations. It eliminates the need for multiple local carriers and consolidates voice infrastructure into a unified platform.

Carrier flexibility

Direct Routing lets enterprises choose their own telephony provider instead of relying solely on Microsoft Calling Plans. This choice enables businesses to negotiate better rates, maintain relationships with trusted carriers, and optimize voice spending based on geography and usage patterns. It also allows organizations to port existing numbers and keep service continuity without mandatory provider changes during migration to Teams.

System integration

Many enterprises operate hybrid environments with legacy systems such as on-premises PBXs, analog lines (e.g., fax or lift phones), or existing SIP devices. Direct Routing supports seamless integration between Microsoft Teams and these systems through SIP and SBC configurations. This ensures that businesses can adopt Teams for voice without abandoning critical legacy systems or undergoing costly hardware replacements all at once.

Custom call routing

Direct Routing offers advanced call control features, allowing enterprises to design and implement complex routing policies. This includes setting up business hours routing, call overflow handling, failover routing to backup sites or mobile devices, and call masking or number presentation rules. These capabilities give IT teams the control they need to meet operational, security, and compliance requirements across different business units or locations.

Pure IP has been an instrumental partner in the global telephony migrations I have worked on over the past few years. Their expertise and services have been a key driver in streamlining what is sometime a complex journey to Microsoft Teams. By moving to Operator Connect with Pure IP, the businesses I’ve worked with have significantly reduced their dependency on on-premise telephony, making operations much more efficient. Their support has been invaluable in these transitions.
