Introduction
Modern businesses demand unified communication platforms that combine collaboration and enterprise-grade voice calling.
While Microsoft Teams excels at messaging, meetings, and collaboration, 3CX provides powerful PBX capabilities.
Integrating Microsoft Teams with 3CX allows organizations to leverage the strengths of both platforms
in a seamless and cost-effective way.
In this guide, we explain how MS Teams with 3CX integration works, its benefits,
and why it’s becoming the preferred communication model for SMBs and enterprises alike.
Why Integrate Microsoft Teams with 3CX?
Microsoft Teams alone requires additional licensing and configuration for advanced telephony features.
3CX, on the other hand, is a software-based PBX system that supports SIP trunking,
advanced call routing, IVR, and call center functionality.
By integrating the two:
- Teams becomes your collaboration interface
- 3CX becomes your telephony engine
- Users get enterprise calling inside Teams
- Businesses reduce Microsoft calling plan costs
Key Benefits of MS Teams + 3CX Integration
1️⃣ Cost Savings
Organizations can use SIP trunk providers instead of expensive Microsoft Calling Plans.
2️⃣ Advanced Call Management
3CX provides:
- Auto-attendants (IVR)
- Call queues
- Ring groups
- Call recording
- CRM integration
3️⃣ Flexibility & Scalability
Whether you’re a startup or enterprise, the solution scales easily
without major infrastructure changes.
4️⃣ Centralized Communication
Employees use Teams as a single interface for:
- Chat
- Video meetings
- Voice calls (via 3CX)
- File sharing
How the Integration Works
The integration typically uses:
- Direct Routing or SIP Trunk configuration
- Session Border Controller (SBC)
- 3CX PBX platform
- Microsoft Teams Admin configuration
The result: users can make and receive external PSTN calls directly from Microsoft Teams
while 3CX handles routing and telephony logic.

- Companies looking to reduce telephony costs

Final Thoughts
Integrating Microsoft Teams with 3CX creates a powerful, scalable,
and cost-efficient communication system. It combines collaboration,
enterprise telephony, and advanced PBX features into one streamlined experience.
If your organization is looking to modernize communication infrastructure
while controlling costs, MS Teams with 3CX is a solution worth considering.
