If you're in a quiet place, you can hear the coin tones on a D
set, but just barely.  I assume it's unintentional (like the
slight amount of pulse clicking you can hear on most rotary
phones despite the receiver being "muted").

If you know of a way to change the "muting" to something more
like the attenuation applied by touch-tone dials when sending
DTMF signals, I'd be interested.  Presumably there's a switch
opening somewhere in the phone that could be defeated with a
jumper or resistor (non-permanently).

I'd like to have an un-modified three-slot.  Unfortunately,
those don't seem to exist anymore.
