Shawn:

If you are asking about a standard (POTS or plain old telephone service
in the USA) telephone - try damping the ringing output transducer. I
have used tape on the both old mechanical bell type and the piezo type.
If a mechanical bell tape the clanger - you still will hear a muffled
clanking from the armature. If you have an electronic phone that does
not have the mute function - with the enclosed piezoelectric type - tape
over the air vent holes. With the open piezo type - put tape right on
the piezo disk or use silicon rubber (RTV).

You can't shunt the ring signal on the telephone line itself without
stopping all phones from ringing because, of course, all extensions are
on the same two wires. If you have a common pair to the extension phones
that can be separated from the main phone input telephone service - you
could add a network that passes on to the extensions the voice + 48VDC
but not the higher voltage (90VAC) low frequency (20Hz) ringing signal.
