Ring tone advertising campaigns have become hugely popular, though they have also attracted a great deal of criticism.
A phone only rings when a special "ringing signal" is sent to it. For regular telephones, the ringing signal is a 90-volt 20-hertz AC wave generated from the switch that the telephone is connected to. For mobile phones, the ringing signal is a specific radio-frequency signal.
