I have noticed phones with a handset (like the one in the image) have a little cover that resembles something like a cold camera shoe under the bottom of the handset’s top speaker holder. Is there a use for it? It has a line bump in the middle, but it doesn’t go all the way from both sides, it leaves a gap. I have also seem some of them have extra space on the top of the cover, and some don’t.
Yes! Another phone nerd!
One small clarification. There’s not really anything special to the pulses for pulse dialing. One pulse for the number 1, all the way to nine pulses for number 9, and then ten pulses for a number 0.
