When a setting in an IP telephone terminal is to be changed, a remote resetter registers subscriber information corresponding to this IP telephone terminal and places a call to this IP telephone terminal. The IP telephone terminal sends a setup request to a setup server if an incoming call is from a pre-registered source. When the IP telephone terminal receives, as a response to this request, setup information from the setup server, the IP telephone terminal sets the setup information and sends a setup completion notification to the remote resetter. Upon receipt of the setup completion notification, the remote resetter deletes the subscriber information corresponding to this IP telephone terminal.
