How to Click-to-Call 

There are several configurations required to enable click-to-call from a browser. These include operating system, web programming, and browsers themselves

Windows 10

Configure Operating System

Note: Other versions of Windows might have different specific instructions. 

The first step is to ensure Teams is the default application for the TEL protocol on your local computer in the operating system properties.  Protocols are bits of code that trigger actions from installed applications.  An example is when you click a link that starts with HTTP. HTTP is a protocol associated with your default web browser.  Enabling click to call works in the same fashion, but instead of HTTP the most common protocol for telephony is TEL.  

Click Windows + I key to open Settings.  Search for "protocol" and select the Choose default apps by protocol option
