The click-to-call (or click-to-dial) feature lets you dial phone numbers by clicking specially formatted links on websites, CRM or other web or native applications.

How does it work?

It works by associating the desktop client (currently supported on Windows only) as a default app for the operating system's tel: and call to: protocols. The system then launches the associated app when clicking on the tel: or call to: links in any web or native application that supports functionality.

On the web pages where phone numbers are not formatted as either tel: or callto: links, you can install a browser extension (e.g., Telephone Number Detection) that parses a web page and turns any phone number it finds on the page into the properly formatted links, enabling click-to-call functionality.

Enabling click-to-call

First, install the desktop app on your Windows device.

On the Start menu, select Settings  > Apps > Default apps.

Scroll down and navigate to choose defaults by link type (or choose default apps by protocol in Windows 10).
