If you're talking about Jitsi Meet, and to add another perspective: I have tried to install it and failed. Specifically, you could see that other participants have joined, but you could not see their video.

I have tried to set it up in different ways multiple times, following all the steps of the fantastic documentation meticulously, with full server resets in-between, researched the error messages thoroughly and even asked in the Jitsi forums, but there was just no way.

But if it works, it's a great piece of software that's easy to set up with really great documentation. I'm blaming the fact that it didn't work out on the hosting company (Strato) and their wonky VPS.
