How to organize a web video conference?

Question

Video broadcast

Please help, I need to organize a video conference on the site, it would seem that it would be easier, but here are a few nuances:
1. The server part of the video conference should be installed on my iron server.
2. You can get a video conference recording.
3. The maximum number of participants is not less than three.
4.many different rooms.
5. Room management goes through the web interface (bare browser)
6. The conference itself also takes place through the web interface (bare browser) at a certain time
7. the budget is limited.
I shoveled everything I could, as a result, the most suitable ones were:
1.3CX (in the free version, at my request, I can only hold one conference at a time)
2.OpenMCU (no client for the web interface)
if there are any possibilities please let me know, even if it is paid but with a reasonable price.
PS Thanks in advance
Maybe you should try Big Blue Buton if anyone has documentation in Russian please send it off

Answer 2

it would seem easier

almost everything is simpler than a video conference.
You can take something ready-made for webinars, but it will not be on your server, but you can insert it on the site. For example:
https://boomstream.com/ru/
https://www.imind.ru/
