In this unit, you will learn that the softphone interacts with your browser and that you must ensure it has permission to use your microphone.
The Fastcall softphone works through your web browser. It tries to use your computer’s microphone, but in order to do this, your web browser must give it permission. Modern web browsers will prompt the user to do this, and then will trust that site later on.
The interface for doing this will change based on your browser but will look something like this.
A web search for “your-browser-name microphone permissions” should tell you what you need to know.
