Hi, JepZoomie. Sorry for the delay. I lost track of the question I had asked. Thanks for the input. I will research the link that you provided.
Earphones won't help in this case. I need a solution that requires her to do nothing at all, other than to start talking to me when I start talking to her. The audio on ViewClix is often horrible. I know because, in the worst instances, it echoes in her room almost 2 seconds after everything I say, making it almost impossible for me to talk. Other times my audio comes through garbled -- and often the very first syllable is somehow "cut off" on every other word I say. Logging off and on ViewClix will usually improve the audio somewhat, but not always.
I've investigated the problem and nothing's helped. The Viewclix company says that the device may be affected by other nearby electronics. If so, that makes Viewclix hard to use in the kind of setting where my mom is located, because living units are side by side, separated by a thin wall, with a big TV screen in every room.
The facility has made some efforts to help, but in my opinion, facilities for the elderly should be much more engaged in this issue. As it is, when I call them, I'm very lucky if I find someone who understands how to use the TV remote, let alone how to make sure that my mom can engage in hands-off communication with me via the Internet.
I know through research (and my nephew who's a programmer) that it is technically possible to set up a system in which a TV (connected to Wi-Fi) can double as a way to remotely communicate with the person watching TV. If I ran a home for the elderly, I would have this feature on every TV, so that family members could jump on at any time and say hello to and talk with their loved one -- or even help the elderly parent find the shows that they want to see.
But that's just my two cents' worth on the topic.
As for using Zoom to accomplish what I'm after, it sounds like the link you provided might help, so I'll be checking it out as soon as I get a spare moment.
I'll post back here to report on what I find.
