When you talk into a telephone, the microphone inside of the mouthpiece transforms the sound waves into electric impulses.
These sound waves are sent through the cable to the ear piece of the other persons receiver which they are listening. This turns the impulses into sounds which are nearly identical to the sound made by the caller, so from the impulses sent it sounds like they are standing right next to you.
