Please explain what do you mean. The TURN server is a relay server.

The Debian coturn package that was taken by Ubuntu is a generic TURN server. If you want a particular specific TURN server configuration, then you can always create a new Debian/Ubuntu package that depends on the coturn package and then it configures the coturn according to your specifications. If you can create and maintain such a package, then it will be great.
