A telephone exchange apparatus includes an acquisition unit, an extraction unit, a specification unit, and a call control unit. In a case where an incoming call including a user ID is detected, the acquisition unit acquires event information of a user having the user ID, the event information indicating a schedule event. The extraction unit extracts location information of the user from the event information. The specification unit specifies a telephone terminal to which the user is most likely to respond among telephone terminals on a basis of the location information, the telephone terminals having been used by the user in a past. The call control unit causes the specified telephone terminal to ring.
