If you know how set up a ringing service all you need do is change its operation from manual to automatic. If you are asking for detailed instructions on how to set up a ringing service, that is beyond the scope of this forum.

Either research it in the installer manual or hire a qualified tech who knows how.

Sorry to be so blunt.
