An auto-dialer is an electronic device that can automatically dial telephone numbers to communicate between any two points in the telephone, mobile phone and pager networks. Once the call has been established (through the telephone exchange) the auto-dialer will announce verbal messages or transmit digital data (like SMS messages) to the called party.
