The telephone 4 of the present invention receives a caller telephone number notified from the public station telephone exchange 3 at the time of an incoming call, a caller telephone number detecting means 41, a telephone number discriminating and converting section 42, a telephone number and A telephone number storage means 43 in which relevant data is preset and stored, a sundial time means 44 for timing the date and time, and a caller telephone number display for displaying the caller telephone number sent from the telephone number discrimination conversion section 42. Incoming call history data registration means for registering data such as the date and time at the time of incoming call and the number of incoming calls from the same telephone number based on the date and time at the time of incoming call and the caller's telephone number sent from the means 45 and the telephone number discrimination conversion unit 42. 46 and. The telephone number discriminating / converting unit 42 determines whether the telephone number detected by the caller telephone number detecting unit 41 is from the call-dedicated line or not.
3 is referred to, and the telephone number storage means 43 is referred to when the number is from a call-dedicated line, and a number for extracting the corresponding recallable telephone number is stored. And a conversion means 422.

FIG. 2 is a diagram showing an example of data stored in the telephone number storage means 43 of FIG. The caller telephone number D1 indicates the telephone number detected by the caller telephone number detecting means 41. The outgoing call dedicated line flag D2 is set to * when the caller telephone number D1 is the telephone number of the outgoing call dedicated line, and is distinguished from others. For this reason, the telephone numbers assigned to the call-dedicated lines are investigated in advance for affiliated companies that use the PBX or key telephone system, and the caller telephone number D1 and the call-dedicated line flag D2 are stored in the telephone number storage means. Four
It shall be registered in advance in 3. The sender name D3 is the name of the sender and may be displayed together with the telephone number.
The recallable number D4 is set in the outgoing leased line flag D2 *
Is a callable telephone number that is registered in association with the caller telephone number D1 marked with.
