It would not be a good idea to not have a modular plug when you use an

It is an emergency phone in an elevator so that will never happen.

I think the better way would be to use
a phone faceplate with filter inside.

That is what I want to do but the phone is attached to the wall and
there is no apparent way to get it off.
