2. Description of the Related Art With the advance of network technology, information communication needs have been increasing, and services have been diversified correspondingly. For example, in the conventional proxy response service for general subscriber telephones, there are two proxy response services, a transfer service and a hold response service.

The transfer service provides a proxy response to an incoming call to an incoming telephone by performing a dial operation or a pickup operation of a specific number on another telephone.
Then, a service in which a person who has made a proxy response performs a dialing operation or a hooking operation of a specific number and transfers the call to the original called party.

In the hold response service, a person who has made a proxy response temporarily puts an incoming call on hold by dialing a specific number or pressing a function button. Then, the service is a service for reconnecting when the called party performs a dial operation of a specific number or an operation of pressing a function button.
