ABSTRACT:
A telephone answering machine including a caller ID extracting part, a transmission period and reading part, a response message reading part and a central control part enables lower cost for the user by limiting the allowable time for a response message by operating the telephone answering machine in a more efficient manner. The caller ID extracting part analyzes a call incoming signal and extracts an area code as the caller ID information. The transmission period reading part reads the transmission period per unit cost that corresponds to the matching area code. The response message reading part reads a response message associated with the transmission period per unit cost. The central control part controls the processing and outputting of the response message of a voice recording from the caller or other operations such as remote operation use by the caller based on the caller ID. Depending on the location and/or telephone number of the calling party, the answering machine lowers user cost by limiting the allowable time for a response message and responding to incoming calls in a more efficient manner.
