Couldnt you hold your cellphone next to the microphone in the elevator and just press "1" on it to choose an option? I think the way these multiple choice machines work is the scoop out for the sounds each phone key makes when pressed, so something like this could probably work
Is this a safety risk? If the elevator got stopped and they pushed the "call for help" button, what would happen?
