Hello I need to know how I can keep my link permanent ???
Welcome to the forum.
I suspect you mean your meeting link on the public meet.jit.si? If so, your best bet is to create a link that’s so unique, it’s hard to guess. Because, by design, rooms (and meeting links) are not permanent in Jitsi and that means anyone can use any room name (or link) at any time, if it’s not already being used. So, to reduce the chances of someone else using the same meeting name (and link), make your meeting name very unique (consider using a UUID).
