Jitsi license

How does jitsi use a license to allow only specific ip access

Do you want to allow only clients from a specific IP to access your Jitsi server? If so, this is related in firewall rules, not directly related with Jitsi.

thank you, i will try it

The way I am most looking forward to is to provide an encrypted code to the client calling the jitsi service, and the jitsi service can be accessed only after the authentication passes, otherwise, it cannot be accessed.

Secure domain setup, token authentication or eparto.net may help.
