[Problem to be solved by the invention]

With conventional missed call forwarding, when an individual leaves his or her permanent telephone terminal and moves to another location, he or she must dial a special number and the destination telephone number to register the missed call at the exchange. For this reason, registration cannot be performed unless the phone number of the destination is known, and if the user moves to another location, there is a drawback that the user must cancel/register missed call forwarding again from the resident phone terminal. .

An object of the present invention is to register missed call forwarding by tedious manual dialing at a telephone terminal at a permanent location.
The purpose is to eliminate the hassle by making it possible to release the device with a one-touch operation of inserting a magnetic card from a mobile phone terminal.

[Means to solve the problem]
