What is the best choice for video conferencing?

Question

Video

Hello!
The client wanted a video conference site on his wordpress site, it was with a plugin that he found only this https://wordpress.org/plugins/videowhisper-video-p...
as I understand it, his usual virtual hosting will pull out no more than 10 connections (listeners). ..
Can choose some service and not bother with plugins, is there something free for a small number of listeners?
And here, for example, Skype, this is also what you need, only there is a limit of 10 people .... and YouTube, as I understand it, is the same?
Thank you.
