[Problems to be Solved by the Invention] However, in the conventional device, the setting and cancellation of the answering machine can only be performed on the base unit, so it is necessary to go to the base unit each time the operation is performed. Furthermore, if you want to be able to record an announcement that automatically answers an incoming outside call, the recording must go to the base unit, so any changes to the recorded content must also go to the base unit. If you want to listen to the recorded content while you are away, you cannot play it unless you operate the base unit, so if you take the slave unit out to the garden and want to listen to the recorded content, you have to go back to the base unit. . Even if you want to record important content during a call, you still have to go to the base unit to record, so there is a problem in that you may miss the timing to record.

[Means for Solving the Problems] In order to solve such problems, the first invention provides a recording and playback unit in the base unit, and sets the base unit to an answering recording/waiting recording cancellation mode that is transmitted from the slave unit. It is designed to set itself to the corresponding mode based on the reception of a signal. Second
In this invention, the base unit updates the currently recorded response message with the voice message transmitted from the slave unit based on the reception of the response message change signal transmitted from the slave unit. In the third aspect of the invention, the base unit sequentially reproduces the currently recorded recorded messages and sends them to the slave unit based on the reception of the recorded message reproduction signal transmitted from the slave unit.

The fourth invention is such that the i device records messages sent from the telephone line based on reception of a recording control signal sent from the slave device.

[Operations] In all of the first to fourth inventions, the recording and playback state can be controlled from the slave unit.
