there are so many suggestions and comments that are incorrect that I do not have time to go into them all, but the legit suggestion was to attach a lamp to your phone. Another suggestion would buy an external ringer that plugs in series with your phone.
Another idea would be to keep your feet on a wet towel. Half-tap two wires onto the tip and ring side of your phone jack, and then attach the bare ends to your nutsack with electrodes. That way, everytime ringing generator applies the -120vDc you will know it right away, and will likely answer your phone on the first ring, every time
