ABSTRACT:
A facsimile, or telephone, according to the present invention predicts a telephone number to be dialed based on a number corresponding to a dial key depressed by a user, to automatically dial remaining numbers for the telephone number. The facsimile, or telephone, has a memory for storing telephone numbers and a number of dial keys. It is checked whether at least one of the dial keys is depressed by the user. If the user has depressed at least one of the dial keys, the facsimile, or telephone, generates a dual tone multi-frequency signal corresponding to the dial key depressed, and searches the memory for a telephone number corresponding to the dial key depressed. Thereafter, the facsimile, or telephone, displays the telephone number searched, and generates dual tone multi-frequency signals corresponding to remaining numbers for the telephone number searched, upon depression of an automatic dial key by the user.
