Real phones with a dial and a bell were rung by the line (a 48V ac signal which is surprisingly painfull for such a low voltage) modern phones detect the signal and sound a peizo buzzer, the line still sends the same signal, phone people are obsessed with backwards compatibility.
I suspect that you, like I, had the experience of installing a phone line at the moment someone called. A SHOCKING sensation!
