Telephone apparatus with automatic dialing function

The automatic telephone answering apparatus of this invention is capable of connection to a plurality of telephone lines. The user registers in this apparatus the telephone number of a telephone equipment where the user will be staying (destination telephone number) and telephone numbers of desired calls. This apparatus detects the telephone number data indicative of the caller's telephone sent from an exchange. When the detected telephone number data agrees with the registered object telephone number, this apparatus automatically calls the telephone of the destination using the registered destination telephone number. If this automatic call succeeds, this apparatus connects the being called telephone line to the telephone line automatically called by the automatic telephone answering apparatus. Therefore, an important call is directly transferred to the user staying at another place, so that the user can directly communicate with the important caller. In addition, the frequency of response to the transferred calls is reduced because the transferred calls are limited to only calls from telephones whose telephone numbers have been registered previously.
