Thank you very much for quick reply. I’ve noticed a section like below in jitsi config.js. For that we can give , that in which JVB the user must connect to.
We can override that feature to identify the user and region. That means as the nearest JVB.
crossRegion: (!'eu-central-1' || 'eu-central-1' === 'eu-central-1') ? 0 : 1
