Telephone answering apparatus adapted to be coupled to a telephone line and having a first storage medium, such as a first magnetic tape, for storing announcement information and remote telephone number information, and a second storage medium, such as a second magnetic tape, upon which are recorded messages which are received via the telephone line. In response to an incoming telephone call, the first tape is driven so as to transmit the prerecorded announcement, and at the conclusion of this announcement the first tape is stopped and the second tape is driven so as to record an incoming message. A timing circuit is actuated for the duration of the incoming message so as to determine whether it exceeds a minimum duration. At the conclusion of the incoming message, a calling circuit is actuated to resume driving the first tape so that the remote telephone number information is transmitted, thereby dialing a remote telephone station. If a user of the machine is located at the remote telephone station, he can transmit a coded signal which is detected by a code detector at the telephone answering apparatus so as to cause the messages previously recorded on the second tape to be played back. In the event that the recorded messages are not played back, for example, if the dialed remote telephone is not answered or if the coded signal is not transmitted, a repeat circuit re-energizes the calling circuit a preset number of times, or until such recorded messages are played back. In another embodiment of this apparatus, the announcement and remote telephone number information which are recorded on the first tape can be revised from any remote telephone station. In a still further embodiment, the first tape also may be provided with a page message which is adapted to be transmitted to an automatic paging installation associated with the remote telephone number. In accordance with this page message, a user of the apparatus, who also is a subscriber to the paging installation, will be apprised that a telephone message had been recorded on his telephone answering apparatus and is awaiting retrieval. |
