Zoom is our official video-conference application. It is used company-wide. All client-facing personnel have an account, and all department leaders (even if they don't talk directly to clients) have an account as well.
The one thing we are solving is making it easy for our clients and potential clients to join a call with us. They just have to follow a link on the calendar invites. Also, we improved a lot the quality of our calls, video calls, and screen sharing. It just works. In the years using it, I have never had a single quality or disconnection problem while using Zoom.
