(Prior art) Conventional telephone forwarding equipment connected to analog telephone networks is a method of forwarding two incoming calls to a preset forwarding destination, and those with forwarding-only functions are generally adopted. has been done.

In addition, the conventional answering machine used when connected to 7sp Gummy Katsugeki automatically answers when two calls arrive, sends a preset answering message, records the message, and transfers the message. Even if the caller has this function, there is only one telephone line, so the method is to record the caller's message, then end the call, and then convey the caller's recorded message to the forwarding destination. has been adopted.

Also, in conventional telephone transfer devices or answering machines.

When calling the called party, the caller sends a memorized number after the automatic answer when the call arrives and stops the forwarding function or answering function. The commonly used method is to call

(Problems to be Solved by the Invention) Conventional forwarding telephone devices and answering machines operate as exclusive functions for forwarding and answering as described above, so it is difficult for the user (operator) of the forwarding telephone device or answering machine to operate as a dedicated function. Depending on the situation and purpose, use a forwarding telephone device or
You will need to decide whether to use an answering machine and install or change the device for your intended use.

If the user misunderstands the intended use of the device (for example, using the forwarding function instead of the answering function).

There is a problem that callers may be forwarded unnecessarily.

In addition, when providing special functions (such as stopping the forwarding or answering function and calling the first called party when forwarding or answering is activated), it is necessary to agree on a PIN number between the user and the caller. shall be.

(Means for solving problems) The present invention aims to solve the above-mentioned problems in advance.
