All of the other answers mentioning coturn here are wrong - your friend is trying to call you using element call, which needs an instance of a livekit and a JWT micro service to grant permissions to use the livekit instance. You can use a livekit cloud account, but you do need to host the JWT service. I would suggest looking up Element’s documentation

Actions is significantly better, there are lots of subtle UI improvements, there are new importers, etc. Not a killer feature, but many small improvements that add up.
