Integrasi Microsoft Teams dengan Sistem Telepon Bisnis

 

Microsoft Teams has become the primary collaboration platform for many enterprises. However, for professional, flexible, and controlled business telephony (PSTN Calling), integration with a reliable telephony system is essential. Through Direct Routing, Microsoft Teams can be integrated with 3CX IP PBX acting as a Session Border Controller (SBC). This solution enables organizations to use Microsoft Teams for making and receiving phone calls using their existing telephony infrastructure.

What Is Microsoft Teams Direct Routing?

Direct Routing is Microsoft’s official method for connecting Microsoft Teams to a third-party IP PBX or SIP Trunk, eliminating the need for a Microsoft Calling Plan.

 

With Direct Routing, enterprises can:

 

  • Retain existing phone numbers
  • Maintain full control over call routing
  • Optimize and reduce communication costs
  • Seamlessly integrate Microsoft Teams with enterprise PBX systems


The Role of 3CX as a Session Border Controller (SBC)

 

3CX serves as a Session Border Controller (SBC) that bridges Microsoft Teams with phone networks (SIP Trunk / PSTN).

 

Key Functions of 3CX as an SBC

  • Securing SIP Communications: Encrypts and protects signaling and voice media streams.
  • Managing Signaling and Voice Media: Handles call setup and media flows seamlessly.
  • Maintaining Voice Quality (QoS): Ensures optimal voice delivery and network reliability.
  • Controlling Inbound & Outbound Routing: Directs incoming and outgoing call flows efficiently.
  • Integrating Advanced Features: Centralizes call recording, call logs, and reporting.
With 3CX, Microsoft Teams doesn’t operate in isolation—it becomes an integral part of a centralized enterprise phone system.
