ABSTRACT:
A redialing system for use in an apparatus, such as a telephone unit, connected to a telephone network includes a telephone number memory for storing up to a predetermined number of telephone numbers each time when input and a character display unit for displaying desired information, including a telephone number. Each time when a recall button is depressed, another telephone number is read out from the memory and displayed at the character display unit in a predetermined order. When a redial button is depressed with a desired telephone number displayed at the character display unit, a call is automatically placed to a station of that desired telephone number.
