Voice switches are all digital now, so handsets using pulse dialing (analog) no longer work. DTMF replaced pulse dialing, so any handset using DTMF should still work on a POTS line today.
Of course there may be a pocket in the world sill using pulse, but I doubt it. The parts for analog voice switches have been manufacturer-discontinued for decades.
