This integration enables organisations to use their existing phone systems while taking advantage of Teams' collaboration features, resulting in a unified communication environment. The Microsoft Teams’ Direct Routing enables low-cost global calling, greater freedom in telecom provider selection, and improved call control.
The UCaaS teams’ integration with businesses can streamline operations, decrease overhead, and improve user experience by utilising capabilities such as call transfer, voicemail, and conference calling.

This seamless communication solution increases productivity and provides consistent, high-quality interactions across several platforms, making it a must-have for modern businesses looking for practical, scalable communication solutions.
Understanding Microsoft Direct Routing & UCaaS
Microsoft Direct Routing enables enterprises to link their telephonic infrastructure to Microsoft Teams, resulting in seamless collaboration. It connects with Unified Communications as a Service (UCaaS), providing a cloud-based audio, video, and messaging solution.
The UCaaS market is predicted to increase from $44.68 billion in 2024 to $139.94 billion in 2029, with an annual growth rate of 25.65%. This connection improves collaboration, lowers expenses, and streamlines communication by leveraging Microsoft's robust cloud environment and superior telephony features.
The benefits of integrating Direct Routing with UCaaS
Here's how integrating Direct Routing with UCaaS is beneficial:-
1. Integrate seamlessly with existing systems
Direct Routing enables seamless interaction with current communication systems and procedures. It allows enterprises to move to a UCaaS platform while maintaining their present telephony infrastructure. This UCaaS integration ensures a smooth transfer process and allows staff to use familiar tools and methods. It also enables incremental adoption of new UCaaS features, making the shift more feasible for organisations.
2. Simplified administration and management
Integrating Microsoft Direct Routing with UCaaS streamlines communication system administration and maintenance. Thanks to centralised control via a single UCaaS platform, monitoring, reporting, and troubleshooting are more accessible. IT departments can efficiently handle call routing, user permissions, and other administrative activities, freeing up resources for strategic initiatives.
3. Enhanced global reach
Direct Routing with UCaaS can considerably increase global reach for organisations that operate in multiple countries. It enables linking local SIP trunks in many countries, helping local presence while lowering international calling expenses. This capacity improves communication with global clients and partners, resulting in more efficient and cost-effective international operations.
Key features of Microsoft Direct Routing
One of the primary features of Direct Routing is the ability to leverage existing telephone infrastructure, such as legacy PBX systems and analogue devices. This allows organisations to leverage their existing assets while migrating to a modern communication platform. Direct Routing reduces costs by allowing for more flexible and competitive pricing alternatives from several telephony providers.
Global reach and scalability
Direct Routing enables organisations to reach worldwide by connecting their SBCs to the Microsoft Phone System in various locations. This provides regular and reliable communication among offices and countries. Direct Routing's scalability enables enterprises to extend their telephony capabilities as they grow.
Security and compliance
Direct Routing relies heavily on security measures. It secures the connections between the organisation's SBCs and the Microsoft Phone System, including voice traffic encryption and regulatory compliance assistance. This makes it an excellent alternative for industries with strict security requirements.
Monitoring and analytics
Direct Routing offers extensive monitoring and analytics capabilities, providing information about call quality and usage patterns. These solutions assist IT administrators in managing and optimising their telephony infrastructure, ensuring high-quality communication experiences for end users.
Steps to integrate Microsoft Direct Routing with UCaaS
Microsoft Direct Routing connects your UCaaS platform to Microsoft Teams, allowing businesses to make and receive calls via the familiar Teams experience. Here is a breakdown of the stages involved.
Preparation
- You need a Microsoft Phone System licence and a Direct Routing or Calling Plan licence. Calling Plans are Microsoft-managed services, whereas Direct Routing allows you to use your current phone carrier and numbers.

Configuration
- Set up SIP trunks with your UCaaS provider. These virtual connections allow you to route calls between your UCaaS platform and Microsoft Teams. If you have a phone system, you can use existing SIP trunks.
- Configure Direct Routing settings in the Microsoft Teams admin centre to allow your tenant to recognise your preferred UCaaS provider. This includes providing SIP trunk setups and authentication mechanisms.
- You may assign phone numbers to your users and departments within the Microsoft Teams admin centre. You can port existing numbers or obtain new ones from your UCaaS provider.
Testing and Deployment
- Before implementing the integration for all users, undertake extensive testing to guarantee call quality, functionality, and emergency service compatibility.
- Once testing is completed, you can make the integration available to your users. This might include teaching them how to use Microsoft Teams' calling tools.
