Multiple config.js files for one Jitsi meet instance


is it possible to use multiple config.js files to join one room with different URLs?
My idea was to use two different configs, one for computers with good bandwith and one config for phones with lower solution and bitrate for example.


Not really but you can override some parameters with the URL Api,, the complete parameter list (unfortunately without any explanation) is here

Yes, it is possible, actually. You’d need to define multiple nginx configurations all leading to the same Jitsi instance - basically, you would need to extend multi-tenancy in your deployment.
