My parents recently got a pushbutton phone which is on a non-touch-
tone line.  The phone has a switch for pulse or tone, and you must
call using pulse (attempting to use tone will not break the dial
tone), but you can then switch to tone for subsequent touch-tone
inputs (including the self service credit-card-number entry).
