How do I initiate a video call?

Watch a step-by-step tutorial on how to join a video call here.

After sending a video call invite (see how to do that here) select Start Video Call and go to a Waiting room. Select a client and click Join call. Wait for the client to join the call. 

Make sure you and your client allowed your internet browser access to your device's microphone and camera - this can be managed in the browser settings.
