Due to upcoming changes in popular browsers, the 3CX Browser Extension will no longer function as a softphone (allowing users to make and receive phone calls from the extension).
The 3CX Desktop App will take the place of the 3CX Brower Extension. After upgrading to the 3CX Desktop App you may wish to leave the 3CX Browser Extension installed as it will function as a "click-to-call" extension allowing you to initiate a phone call by clicking a phone number within the browser.
Please follow these steps when presented with the following message
