An auto call system is provided to enable a user to automatically call through only one auto call button in which a telephone number is stored without additional cost. An auto call system uses a call bell which performs a call by using an abbreviated dial previously stored without direct calling and does not require the cost for telephonic communication by adjusting the number of times a call signal, not having a purpose for the telephonic communication, is originated. The auto call system comprises number LEDs capable of recognizing the number of call bells and an LRD capable of recognizing the pressing of a bell, sound and light. |
