In 2026, businesses want more flexibility, global coverage, cost efficiency, and control over their communication infrastructure. Direct Routing offers all of these advantages by allowing companies to connect their own telephony provider to Microsoft Teams using a Session Border Controller (SBC) and SIP trunking.
For organizations looking to modernize communication without replacing their existing telecom infrastructure, Direct Routing is becoming the preferred solution. Let’s explore why businesses are rapidly adopting this approach and how it works.
What Is Direct Routing for Microsoft Teams?
Direct Routing for Microsoft Teams is a solution that allows businesses to connect Microsoft Teams directly to the Public Switched Telephone Network (PSTN) through a certified Session Border Controller (SBC) and a SIP trunk provider.
In simple terms, it enables Teams users to make and receive external phone calls directly from the Teams interface while using their own telecom provider.
Instead of relying solely on Microsoft Calling Plans, organizations can connect Teams with their existing telephony infrastructure, SIP trunks, and phone numbers.
This approach gives businesses the flexibility to customize their communication system while keeping Teams as their central collaboration platform.
How Direct Routing Works
A typical Direct Routing Microsoft Teams setup includes:
-
Session Border Controller (SBC)
-
SIP trunk provider
-
PSTN connectivity
The SBC securely connects Microsoft Teams with the telecom provider’s network, enabling voice calls between Teams users and external phone numbers.
This architecture allows companies to integrate Teams with existing PBX systems, analog devices, or global voice networks.
Why Businesses Prefer Direct Routing for Microsoft Teams in 2026
Organizations are adopting Direct Routing because it offers several advantages over traditional calling solutions. Let’s explore the most important reasons.
1. Greater Flexibility and Control
One of the biggest advantages of Direct Routing for businesses is flexibility.
With Microsoft Calling Plans, companies are limited to Microsoft’s supported countries, pricing structures, and features. Direct Routing removes these limitations.
Businesses can:
-
Choose their preferred SIP trunk provider
-
Configure custom call routing policies
-
Integrate legacy PBX systems
-
Use existing phone numbers
Direct Routing allows companies to build a communication system tailored to their specific needs rather than adapting to a fixed platform.
For organizations with complex telecom environments, this flexibility is invaluable.
2. Cost Savings for Large Organizations
Cost efficiency is another major reason businesses are switching to Direct Routing.
Microsoft Calling Plans typically charge per-user monthly fees that include bundled minutes. However, many organizations do not fully use those minutes.
With Direct Routing:
-
Businesses pay per SIP channel or per minute
-
Calls can be routed through lower-cost carriers
-
International calling costs can be optimized
This model is particularly beneficial for companies with high call volumes or international operations, where telecom expenses can quickly add up.
By using their own carrier agreements, businesses can significantly reduce communication costs.
3. Integration With Existing Telephony Infrastructure
Many companies already have significant investments in telecom infrastructure such as PBX systems, call centers, and analog devices.
Direct Routing makes it possible to integrate these systems with Microsoft Teams instead of replacing them completely.
Organizations can connect:
-
Legacy PBX systems
-
Contact center platforms
-
Analog phones and devices
-
Existing SIP trunk services
This hybrid approach allows companies to migrate to Teams gradually while keeping their current voice environment intact.
For enterprises with complex telecom setups, this reduces disruption and implementation costs.
4. Global Coverage and Number Availability
Microsoft Calling Plans are only available in limited regions. For multinational businesses, this can be a major limitation.
Direct Routing solves this problem by allowing companies to use global SIP trunk providers that offer phone numbers in many countries.
Businesses can:
-
Deploy local numbers worldwide
-
Support global teams and remote workers
-
Maintain consistent communication across regions
For international companies, this means they can build a truly global voice network integrated with Microsoft Teams.
5. Improved Call Quality and Reliability
Call quality is critical for business communication.
With Direct Routing, companies can choose telecom providers with carrier-grade networks optimized for voice traffic.
Additionally, features like media bypass and local media optimization reduce latency by allowing call traffic to flow more directly between endpoints.
The result is:
-
Lower latency
-
Higher voice quality
-
Reduced network congestion
For businesses that rely on voice communication, these improvements can significantly enhance user experience.
6. Better Security and Compliance
Security is a top priority for modern organizations.
Direct Routing provides encrypted communication and secure connections between Microsoft Teams and the telecom network. This encryption protects voice data from unauthorized access and cyber threats.
Businesses also gain greater control over:
-
Call routing policies
-
Data compliance requirements
-
Regional telecom regulations
For industries such as finance, healthcare, and government, this level of control is essential.
7. Advanced Voice Features and Customization
Direct Routing enables organizations to extend Microsoft Teams with advanced voice features.
Businesses can implement:
-
Custom call routing
-
Contact center integrations
-
Analytics and reporting
These capabilities allow companies to create a fully customized enterprise communication platform.
Instead of relying solely on built-in Teams features, businesses can integrate additional voice applications and services.
8. Supports Hybrid and Remote Workforces
The rise of hybrid work has transformed business communication.
Employees now work from offices, homes, and remote locations across the world. Direct Routing allows Teams to function as a complete cloud phone system accessible from anywhere.
Employees can:
-
Make business calls from the Teams app
-
Receive calls on laptops or mobile devices
-
Access voicemail, call logs, and routing features
This centralized communication environment improves collaboration and productivity across distributed teams.
Why Telecom Providers Are Offering Direct Routing Solutions
In 2026, telecom providers are increasingly offering Direct Routing solutions integrated with SIP trunking services.
These providers manage the technical components such as:
-
SBC infrastructure
-
SIP trunk connectivity
-
Number provisioning
-
Call routing
-
Support and monitoring
By partnering with a telecom provider, businesses can deploy Direct Routing quickly without managing complex infrastructure internally.
