To me this is just conference call by another name, with some nice extra features like video and screensharing. We still have people dialing in from mobile, cars, using a variety of devices, forgetting to mute/unmute, having background noise, bad connections, putting the conference mic in a bad location. I remember those traditional conference phones usually having really good microphone quality and noise-reduction. You still have to invest in that gear with hangouts/Zoom/others.
