b. Receive a call
Note :
To receive a call, you need to be already connected to a session. Check the use case "Join a session" to know more about it.
The person on the other end of the line might need to call you with - or without - the camera.
In this case, you will receive a call - like on your phone - and will need to click on "accept" to start the session with camera and/or microphone.
You can now directly talk to one another.
