Calls from Teams, through your 3CX phone system

If your team works in Microsoft Teams, they can make and receive external calls there, using the lines you already have on 3CX. We connect 3CX to Teams via Direct Routing. 3CX handles the telephony and Teams stays your collaboration tool.

The challenge

The problem

Teams is excellent for collaboration, but on its own it lacks the capabilities of a full phone system, such as queues, advanced IVR and call reporting. If you buy Microsoft telephony for every user, the cost rises quickly.

Calls from Teams, through your 3CX phone system

The solution

How it works

Direct Routing

3CX connects to Microsoft Teams and users on both platforms can call each other.

Your own lines

External calls from Teams go through your 3CX lines (SIP trunks). You don’t need a Microsoft Calling Plan.

3CX capabilities stay

Call queues, IVR, ring groups, voicemail, recording and reporting.

Mixed use

Only those who need telephony inside Teams get a Teams Phone license. Everyone else stays on 3CX (app, IP phone, web client).

The outcome

What you gain

  • External calls from Teams with your company number
  • The lines and call rates you already have on 3CX
  • Lower licensing cost: Teams Phone only for the users who need it, while 3CX is licensed per system, not per user
  • The 3CX contact center capabilities that plain Teams lacks

FAQ

Frequently asked questions

  • Microsoft: every user who will make or receive external calls from Teams needs a Teams Phonelicense. It is included in Microsoft 365 E5 or added as an add-on (Teams Phone Standard) to other Microsoft 365 licenses with Teams. No Calling Plan needed, because the lines come from 3CX.
  • 3CX: the Teams integration requires 3CX AI Edition, 16 simultaneous calls (16 SC) or more. 3CX is licensed per system, not per user.
  • As a Microsoft CSP partner and 3CX Partner, we supply the right licenses for every user.

No. You can have some users with telephony in Teams and the rest on 3CX only. Everyone can call each other as normal.

Yes. Calls go through the lines you already have connected to 3CX.

No, and it doesn’t need to. Teams stays your collaboration tool and 3CX your telephony. The integration brings them together.
