PURPOSE:To output independently only a calling subscriber number by providing a calling subscriber collating means comparing and collating the contents of a call recorded in response to a call from the calling subscriber with a subscriber number extracted from the calling subscriber number. CONSTITUTION:When a contractor 105 and an automatic answering telephone set 104 are connected, a control section 202 indicates the transmission of message to a message transmitting section 208, and the message transmitting section 208 receiving it transmits a pass word request message signal to the contractor 105. The control section 202 inputs the pass word signal transmitted from the contractor 105 to a pass word collating section 205 and receives the result of collation. When the collation of pass word is coincident, the control section 202 commands again the transmittion of message to the message transmitting section 208, and a pass word confirming message signal is transmitted from the message transmission section 208 to the contractor 105. When the contractor 105 transmits a calling subscriber output request signal newly, then the control section 202 transmits all the calling subscriber numbers to the contractor 105 before the contents of all. |
