How to fix Aircall click-to-call not working on Windows

Before you start (required)

To use click-to-call from our platform, Aircall must be installed as a Desktop App.

The web version of Aircall does not support click-to-call integrations.

Please make sure that:

• The Aircall Desktop App is installed

• The app is open and logged in

If Aircall is not installed as a desktop application, click-to-call will not work.

Problem

When clicking the Call button while performing a call task, the Aircall dialer does not open, even though the Aircall desktop app is installed and Aircall is selected as the VoIP system in Crono (to do this: Account Settings → Integrations → Call).

Cause

On Windows, click-to-call relies on system-level call link protocols (such as TEL:).
If Aircall is not set as the default app for call links, Windows does not know which application should handle the call, so nothing happens when you click Call.

Solution

Set Aircall as the default app for call-related protocols in Windows.

How to fix it (Windows)

1. Open Windows Settings

2. Go to Apps

3. Click on Default apps

4. Select Choose default apps by protocol

5. Scroll down until you find the TEL protocol

6. Set Aircall as the default app
   (If available, we also recommend setting Aircall for the CALL protocol)

Once this is done, return to our platform and click Call again.
The Aircall dialer should now open correctly.

Additional checks

If the issue persists, please verify that:

• The Aircall Desktop App is running (not closed or logged out)

• You are assigned to an active line in Aircall

• The phone number is in international format (e.g. +393401234567)

Still not working?

If you’ve completed all the steps above and the issue is not resolved, please contact our support team and include:

• Your Windows version

• The browser you are using

• Confirmation that the Aircall Desktop App is installed and open

We’ll be happy to help you further.
