A rotary phone circa the 1940s was quite a technological marvel in its day, but we have come a long way since then. The essential elements of these telephones were a microphone to speak into and an earphone which reproduced the voice during a call. In addition, a ringer of some type produced sound to announce an incoming telephone call, and the rotary dial was used to enter a telephone number when initiating a call. This device was connected by a pair of wires to the telephone network, and that was pretty much it.
