An object of the invention is to enable the user, in the case of a wired telephone, to check an incoming call even when the user is not present near the telephone and, regardless of the type of the telephone, enable the user to check calling party information when a call arrives.

When the incoming call notification is received from the gateway apparatus, the PDA causes a ringing tone to sound and displays the received calling telephone number. Further, based on the calling telephone number, the PDA searches telephone directory data stored therein and displays calling party information such as the caller's name.
