PROBLEM TO BE SOLVED: To provide telephone terminal equipment with a call register function, which copes with a crank call that invites return call origination communication. SOLUTION: The telephone terminal equipment with the incoming call history function is provided with a call number-of-times counting part 13 for counting the duration of incoming call notification by incoming call notifying signals from an exchange side or the number of times of calls, a setting part 14 for setting a prescribed threshold for a value counted by the counting part 13, and a filter 15 for comparing the value counted by the counting part 13 with the threshold of the setting part 14, and functions so as to limit operations to a call ringing circuit 16, a memory circuit 12 and a display device 17 until the counted value of the counting part 13 exceeds the threshold. Thus, the telephone terminal equipment with the call register function capable of flexibly coping with the crank call by call origination for which the incoming call notification is realized for an extremely short period for inviting the return call origination communication (call back) or the like.
