we used to dial the phone by clicking the receiver lever instead of using the dial. Worked great for low number calls, like 233-1212. But you get a number with a bunch of 7's, 8's, 9's it was hard to keep the timing correct.
As a bored child, I made a number of telephone calls with nothing more than a small 8 ohm speaker ripped out of a small transistor radio. Place speaker wires across the telephone line, and dial by interrupted pulses as you described being sure to end each pulse train with the wires still connected. You can hear the other party quite well, but you do have to shout at the little speaker (dynamically acting as a microphone) to be heard. But it does work, and could be useful in an emergency.
