3CX Microsoft Teams Integration

3CX Microsoft Teams Integration enables organisations to use Microsoft Teams as their primary business phone interface while routing all external calls through 3CX. This direct routing approach combines the familiar Teams user experience with the advanced telephony capabilities of 3CX — including call queues, IVR menus, call recording, and detailed CDR reporting — features that are either unavailable or significantly more expensive through Microsoft's native calling plans.

With this integration, Teams users can make and receive PSTN calls directly within the Teams client on desktop, mobile, or web. Calls are routed through 3CX SIP trunks, leveraging Xcobean's local carrier connections for cost-effective local and international calling. The integration supports presence synchronisation, so 3CX reflects Teams user availability status and vice versa, preventing calls from being routed to unavailable agents.

For organisations with mixed environments — some users on Teams and others on 3CX desk phones or softphones — the integration provides seamless interoperability. Internal calls between Teams users and 3CX users work transparently, and shared resources like call queues, ring groups, and voicemail boxes are accessible from both platforms.

Xcobean handles the complete Teams integration setup including Azure AD configuration, SBC (Session Border Controller) deployment, DNS record creation, and Teams admin center policy configuration. Our engineers test every call flow end-to-end before handover.
