Abstract
In a telephone having a presence function, it is possible to easily register a presence state. The telephone includes: presence detection means for detecting a presence state of a user; a presence state storage unit for storing the presence state detected by the presence detection means; and control means having a presence modification function for modifying the presence information stored in the presence state storage unit according to the user presence state detected by the presence detection means. When the presence detection means has detected a presence of a user, the control means modifies the presence information stored in the presence state storage unit to presence information indicating a presence. When the presence detection means has detected an absence of the user, the control means modifies the presence information stored in the presence state storage unit to presence information indicating an absence. The control means registers the presence information stored in the presence state storage unit in a presence server.
