Don’t forget Jitsi Meet. Android and iOS apps, web-based otherwise. No need for an account, just make up a meeting room name, tell your friends what it is.

The beauty is that it’s all open source, including the server. The server needs Linux, and they have a how-to on getting it running on an AWS instance. Or you could just put Linux on that old PC in the basement, run the server on that. The nice thing about ‘every organization has a server’ is that it scales — and if you’re concerned about keeping things private (financial data or HIPAA) you can take server (and so conference) security into your own hands.

They keep a jitsi meet server instance running so you can check it out, have a meeting. I’ve discovered that going to the meeting room ‘test’ is a sort of video-chat-roulette. Using their server, I haven’t run into a time limit, nor have I run into a limit to the number of meeting participants.
