For the video add on. There just has to be a button that allows the trainer to extend the session. It's unacceptable that the video stream just ends 5 min after the session no matter what. There are millions of good reasons why the trainer might want to stay on a call with a client and there must be an easy way to do that without interrupting the session. A simple button that says "extend session by X minutes" alternatively the session should just end when the trainer or the client hangs up and not automatically. That would be the preferred way.
