Operator Connect vs Direct Routing: Which Does Your Business Need?

Your organization has committed to Microsoft Teams for collaboration—but which path connects your team to the outside world?

With over 80 million Teams Phone users globally and telephony adoption expected to quadruple by 2027, this decision shapes how your business communicates for years to come.

Key Takeaways

• Both Operator Connect and Direct Routing enable external calling through Microsoft Teams—the right choice depends on your organization's infrastructure, IT resources, and growth plans.
• Operator Connect offers speed and simplicity: Microsoft-certified carriers manage the technical infrastructure, enabling deployment in days and freeing IT teams from telephony maintenance.
• Direct Routing offers control for complex scenarios: Organizations with legacy systems to integrate, specialized compliance needs, or carriers outside Microsoft's certified list may require this hands-on approach.
• Most growing businesses benefit from Operator Connect: With 109 carriers across 106 countries and carrier-managed infrastructure, Operator Connect meets the needs of organizations seeking modern Teams telephony without added complexity.

What Are Your Microsoft Teams Calling Options?

Microsoft Teams offers three primary methods to enable external calling:

• Calling Plans
• Operator Connect
• Direct Routing

Calling Plans represent Microsoft's turnkey solution—simple to deploy but limited in geographic availability and customization. For growing businesses seeking more control over their telephony environment, the real decision comes down to Operator Connect versus Direct Routing.

Both options fall under the "Bring Your Own Carrier" (BYOC) category, meaning you choose your telecommunications provider rather than relying solely on Microsoft. The distinction lies in how that connection gets established and who manages the underlying infrastructure.

Understanding these differences helps IT leaders select the approach that supports their organization's growth trajectory without creating technical debt.

What Is Operator Connect?

Operator Connect is Microsoft's streamlined approach to PSTN connectivity that launched as an alternative to Direct Routing. Through this method, Microsoft-certified telecommunications providers deliver calling services directly through the Teams Admin Center—creating what many describe as an "app store" experience for business telephony.

The setup process works like this:

• Your IT administrator selects a certified operator from Microsoft's directory (currently 109 operators covering 106 countries), and that provider handles the technical heavy lifting.
• The carrier manages Session Border Controllers, SIP trunking, and phone number provisioning on your behalf.
• Your team simply assigns numbers to users through the familiar Teams Admin Center interface.

This approach works well for organizations that want to modernize their phone system without building telephony expertise in-house. Deployment can happen in days rather than weeks, and ongoing maintenance falls to your chosen operator rather than your IT team.

For businesses prioritizing unified communications simplicity, Operator Connect removes significant technical barriers.

What Is Direct Routing?

Direct Routing represents the more established path to Teams telephony, giving organizations complete control over their PSTN connectivity.

With this approach, your organization deploys a certified Session Border Controller (SBC) that bridges Microsoft Teams with any telecommunications carrier you choose—whether that's your current provider or a new one entirely.

This option exists primarily for organizations with specific requirements that fall outside Operator Connect's scope, such as those needing to integrate legacy analog equipment during a phased transition, businesses locked into carrier contracts with providers not yet in Microsoft's certified program, or companies with highly specialized call routing or compliance requirements.

Direct Routing requires significant technical investment. Your IT team (or a managed services partner) handles SBC configuration, SIP trunk management, and ongoing maintenance. Setup typically takes weeks rather than days, and troubleshooting requires deeper telephony knowledge. For organizations without these specialized needs, the added complexity may not deliver proportional value.

Operator Connect vs Direct Routing: Key Differences for Growing Organizations

The choice between these two approaches ultimately comes down to where your organization falls on the simplicity-versus-control spectrum.

Both deliver the same end result—external calling through Microsoft Teams—but the journey to get there differs significantly.

Infrastructure

Infrastructure ownership represents a key distinction.

• Operator Connect places SBC management, carrier relationships, and technical support in your provider's hands.
• Direct Routing keeps these responsibilities with your organization, whether handled internally or through a managed services partner.

For businesses with limited IT resources, the managed approach of Operator Connect reduces operational burden. For organizations requiring precise control over call flows, Direct Routing's hands-on model delivers that capability.

Flexibility & Customization

Customization capabilities separate these options significantly.

Direct Routing enables granular control over call routing rules, allowing organizations to build sophisticated call flows tailored to their operations—route calls based on time of day, geographic location, department, or customer type. Advanced features like call recording, compliance archiving, and contact center integration become possible when you control the SBC.

Operator Connect delivers the functionality your certified carrier supports, which works well for standard use cases but limits organizations with specialized requirements or industry-specific compliance needs.

Deployment

Deployment speed and complexity invert between the two options.

• Operator Connect can have users making calls within days of signing an agreement.
• Direct Routing implementations typically span weeks to months, depending on infrastructure complexity and the scope of legacy system integration.

For organizations prioritizing time-to-value, Operator Connect accelerates adoption.

How to Choose: Decision Factors for IT Leaders

Selecting between Operator Connect and Direct Routing requires an honest assessment of your organization's current state and growth plans. Neither option is universally superior—the right choice depends on your specific circumstances.

Consider Operator Connect when: your organization values deployment speed over customization, your IT team lacks deep telephony expertise, your preferred carrier participates in Microsoft's certified program, you have straightforward calling requirements without complex routing rules, and you want predictable managed services rather than infrastructure ownership.

Consider Direct Routing when: you need to integrate existing PBX systems or analog equipment, your organization operates in countries not well-served by Operator Connect providers, you require advanced call routing, recording, or contact center capabilities, you have existing carrier contracts with favorable rates you want to preserve, or your compliance requirements demand specific control over call data and routing.

Microsoft fully supports hybrid configurations where some users connect through Operator Connect while others use Direct Routing. This flexibility allows growing organizations to deploy Operator Connect for standard office workers while maintaining Direct Routing for specialized functions like contact centers or locations with legacy equipment. The benefits of unified communications extend across both approaches, ensuring consistent collaboration regardless of the underlying telephony path.

Before deciding, assess your current infrastructure honestly:

• Document existing carrier relationships, legacy equipment dependencies, and compliance requirements
• Evaluate your IT team's telephony expertise and appetite for infrastructure management.
• Project your growth plans—will you add locations, expand internationally, or integrate new communication tools?

The answers point toward the option that supports not just today's needs but tomorrow's scale.
