I would start from the assumption that you can't do that, at least on a
landline. Things like T-mobiles "caller tunes" are put on top of the
ring tone.

The other thing I've heard is "instant answer" systems where you are
listening to a ring tone and paying for the call because the far end
has answered, put you on hold and played a ring tone down the line all
in a flash.
