ROAD-VEHICLE TELEPHONE APPARATUS

Dial keys and other keys for a telephone set are provided on an operation board mounted on a steering wheel so as to make an answer-back in accordance with dial operation. The answer-back is effected in terms of numeral values, dial codes or the name of the other party corresponding to each dial code in accordance with operation of the corresponding numeral keys. If a confirmation key is not operated within a predetermined time after an answer-back of the name of the other party, the shortened dial code is updated to another adjacent value to repeat such answer-back sequentially. The name of the other party is issued from a non-volatile memory which stores therein voices of the user.
