Do your dad a favor and buy him a tablet. I'd recommend an iPad for longevity and security reasons. The previous team I was on was internal corp IT. Everyone was begging to ditch GotoMeeting and move to Skype. But Skype was awful as well. So we tested Zoom/Bluejeans/Hangouts and others (went with Zoom, fwiw). We quit bothering with desktop/browser apps for video, and generally stuck to phone for audio only. The Android and iOS experience with all of them was much less flakey.
