You won't believe these 10 facts about people. A dial tone is the signal that a person hears on a landline telephone before he dials a phone number. In most instances, the signal disappears once the first number is dialed. In most cases, cell phones do not have a dial tone.
Dial mechanism: as the dial rotates, it interrupts the circuit between the phone and the exchange creating dialing pulses. If you dial number 9 you create nine pulses, dial 5 and you make five pulses, and so on. Bells: Old phones actually had real, shiny metal bells inside them to indicate an incoming call!
