Epygi is an open-source service that provides access to real-time voice communications via a hosted PBX.

This app, called “Epygi”, is an Epygi browser extension that can be installed on your Chrome browser to detect phone numbers and make one-click calls to the phone numbers.

Epygi can also detect which phone number is on the web page. For example, a user can click on a name or a picture, and a small notification will appear on the right side of the screen with the name of the user and the phone number. The user can also click on the notification to make a call.
