Persistent Room & signaling when some one start over a room

Hi !
Any way to create a persistent room with authenticated user ?
So if the room is persistent ( not removed when all user off), any solution to signal all user that the meeting is restarted ?

There is no such thing as creating rooms and persisting rooms currently. When the last one leaves the room is destroyed.
What is your use case? Why you need to create a room, other then creating a link to a meeting and everyone use that?

My use case is group call like facebook group call : when video call ended, we still see the group, we can chat and create new call without creating new group.
Many thanks!
