Description

The present invention relates to an answering machine corresponding to a caller telephone number notification function.

  An answering machine that responds to an incoming call from a partner and records a message from the other party is widely used in order to accept a message from the other party on the telephone when the user who owns the telephone is absent.

  After the user returns home, when the message reproduction is instructed via the operation unit of the answering machine, the message recorded in the answering machine can be heard. In addition, after calling the answering machine from a telephone outside the office and entering a call state, the DTMF signal is used for remote operation to instruct the answering machine to play the message and listen to the message. Can do.

  Furthermore, in order to improve the convenience of the device, when the out-of-office contact information at the time of absence is known, particularly in recent years, there are overwhelmingly many users carrying mobile phones. The telephone number of the outside contact is registered in advance, and when the message from the other party is recorded, the answering machine calls the telephone of the outside contact, responds with the above telephone, and remotely handles the request. A search function is provided. This is generally called an answering machine transfer function.

  In addition, by receiving the caller telephone number sent from the exchange via the telephone line when receiving an incoming call and displaying the caller telephone number on the telephone, before the user answers the incoming call, A caller telephone number notification function that can specify a caller exists. And the apparatus which receives a caller telephone number is provided with the function which accumulate | stores in a memory | storage means by using the received caller telephone number and the incoming call date as an incoming call history.

Remote operation of an answering machine using a DTMF signal (see, for example, Patent Document 1), answering machine for forwarding to a telephone number stored in the apparatus (see, for example, Patent Document 2), caller telephone number notification function There is known an answering machine (for example, refer to Patent Document 3) using the.
JP 05-268324 A Japanese Patent Laid-Open No. 05-014486 JP-A-11-275211

  The capacity of the storage means for storing the caller's phone number as an incoming call history is limited, that is, there is an upper limit on the number of caller phone numbers that can be stored in the incoming call history. When a caller's phone number is received and received, an incoming call history management method is adopted in which the caller's phone number with the earliest date and time is deleted from the incoming call history and the newly received caller's phone number is stored in the incoming call history. ing.

  The incoming call history management system manages the incoming call history on the premise that the newer caller telephone number of the incoming call date and time is more valuable information.

  Here, when the number of caller telephone numbers has reached the upper limit, in order to allow users to listen to the messages recorded on the answering machine, the destination that is registered in the answering machine as the answering machine forwarding destination Consider a case where a call is made from the contact telephone to the answering machine.

  In this case, since the answering machine receives the caller telephone number when receiving an incoming call from the telephone of the out-going contact, the caller telephone number with the earliest incoming date and time is determined from the incoming call history based on the incoming call history management method. Delete and store the phone number of the outing contact received this time in the incoming call history.

  The caller telephone number notification function is a function for specifying the caller based on the caller telephone number. In addition, when there is no message remaining in the answering machine when there is no telephone call and the caller telephone number is stored in the incoming call history, it is also a function that can make a call to the caller telephone number.

  However, even if the phone number of the out-going contact registered in the answering machine is stored in the incoming call history as the answering machine forwarding destination, the caller can be specified to a very limited person, There is a problem that there is no point in accumulating in the incoming call history because the telephone number is not redialed.

  Therefore, there is a problem that a meaningful caller telephone number is deleted from the incoming call history by storing a caller telephone number that is meaningless to be stored in the incoming call history.

  In addition, even if the number of caller phone numbers has not reached the upper limit, if the answering phone number is stored in the incoming call history, there will be more troublesome operations when the user searches the incoming call history, meaningless operations will increase. There is.

  The present invention provides an answering machine having a function of receiving caller telephone number data sent from an exchange via a telephone line when an incoming call is received and storing the caller telephone number in an incoming call history based on the caller telephone number data. It is an object of the present invention to provide an answering machine that can prevent a meaningful caller telephone number from being deleted from an incoming call history in a telephone apparatus.

Further, according to the present invention, even if the number of caller telephone numbers has not reached the upper limit, the number of meaningless operations is increased when the user performs an incoming call history search by accumulating the answering phone number in the incoming call history. It is an object of the present invention to provide an answering machine that does not make the user feel bothersome.

The present invention provides an incoming call detecting means for detecting an incoming call from a partner machine, a caller telephone number data receiving means for receiving caller telephone number data sent from a switch via a telephone line when an incoming call is received, and the caller Incoming call history storage means for storing the caller telephone number as an incoming call history based on the telephone number data, a display means for displaying the caller telephone number based on the caller telephone number data, and an incoming call from the partner machine An incoming call response means for responding to the call, a playback means for playing back the response message after answering the incoming call, a recording means for recording a voice message from the other party after playing back the response message, and a message for storing the response message and the voice message Storage means, operation means for registering the telephone number for answering voice when the voice message is recorded and forwarded, and the answering machine Answering machine transfer destination telephone number storage means for storing the forwarding telephone number, and outgoing calls received by the caller telephone number data receiving means when the answering machine transfer destination telephone number is registered in the storage means The answering machine is provided with control means for preventing the caller telephone number from being stored in the incoming call history storage means when the telephone number of the caller matches the telephone number for forwarding the answering record.

  According to the present invention, there is provided a function of receiving caller telephone number data sent from an exchange via a telephone line when receiving an incoming call, and storing the caller telephone number in an incoming call history based on the caller telephone number data. When the number of caller phone numbers that can be stored in the incoming call history reaches the upper limit, the caller phone number that is meaningless to be stored in the incoming call history is stored in the incoming call history. Therefore, it is possible to prevent a meaningful caller telephone number from being deleted from the incoming call history.

In addition, according to the present invention, even if the number of caller telephone numbers has not reached the upper limit, the user can perform a meaningless operation when searching the incoming call history by accumulating the answering phone number in the incoming call history. There is an effect that the annoyance caused by the increase is not felt.

  The best mode for carrying out the invention is the following embodiment.

  FIG. 1 is a block diagram showing an answering machine T1 that is Embodiment 1 of the present invention.

  The answering machine T1 includes a CPU 10, an incoming call detection means 11, an incoming call response means 12, a recording / playback means 13, a message storage means 14, a caller telephone number data reception means 15, an incoming call history storage means 16, It has a display means 17, an operation means 18, an answering machine transfer destination telephone number storage means 19, and a bus B1.

  The CPU 10 controls the answering machine T1. The incoming call detection means 11 is a means for detecting an incoming signal from a telephone line, and the incoming call response means 12 is a means for responding to an incoming call in the answering machine mode. The recording / reproducing means 13 is means for recording and reproducing messages, and the message storage means 14 is means for accumulating response messages and voice messages.

  The caller telephone number data receiving means 15 is a means for receiving caller telephone number data sent from the exchange via a telephone line when an incoming call is received. The incoming call history storage means 16 is a means for storing the caller telephone number as an incoming call history, and the display means 17 is a means for displaying the caller telephone number. The operation means 18 is a means for registering an answering machine transfer destination telephone number and for giving various instructions to the answering machine T1, and the answering machine transfer destination telephone number storage means 19 is a telephone which is a destination for forwarding the answering machine. Means for storing a number. The bus B1 is a bus connecting each device / block.

  That is, if the caller telephone number received by the caller telephone number data receiving means matches the answering machine transfer destination telephone number, the CPU 10 receives an incoming call when the telephone number forwarding address telephone number is registered in the storage means. This is an example of control means for preventing the caller telephone number from being stored in the incoming call history storage means.

  Next, the operation of the answering machine T1 will be described.

  FIG. 2 is a flowchart showing a first operation in the answering machine T1.

  First, it is checked whether an incoming signal is detected by the incoming call detection means 11 connected to the telephone line (S1). If the incoming signal is detected, the caller telephone number data receiving means 15 receives the incoming call signal and the caller telephone number data sent from the exchange when there is no sound between the incoming signals (S2).

  Next, based on the received caller telephone number data, the caller telephone number is displayed on the display means 17 (S3). Then, it is checked whether or not an answering record transfer destination telephone number is registered in the answering record transfer destination telephone number storage means 19 (S4). If the answering machine transfer destination telephone number is registered, it is checked whether the answering machine transfer destination telephone number matches the caller telephone number received at the time of the incoming call (S5).

  If the answering machine transfer destination telephone number matches the caller telephone number, the caller telephone number data processing is terminated without storing the caller telephone number in the incoming call history storage means 16. That is, if the caller telephone number received by the caller telephone number data receiving means matches the answering machine transfer destination telephone number, the CPU 10 prevents the caller telephone number from being stored in the incoming call history storage means. By doing this, it is possible to avoid deleting meaningful caller phone numbers from the incoming call history when the number of caller phone numbers that can be stored in the incoming call history has reached the upper limit. In addition, even if the number of caller telephone numbers has not reached the upper limit, it is bothersome because the user adds more meaningless operations when searching for incoming calls by accumulating the phone numbers to which the answering machine is forwarded in the incoming call history. I do not feel.

  On the other hand, if the answering machine transfer destination telephone number is not registered in the answering machine transfer destination telephone number storage means 19 (S4), or if the answering machine transfer destination telephone number does not match the caller telephone number (S5). The caller telephone number is stored in the incoming call history storage means 16 (S6), and the caller telephone number data processing is terminated.

  That is, the CPU 10 receives the caller telephone number received by the caller phone number data receiving unit when the answering machine transfer destination telephone number is registered in the storage unit and is waiting for the recorded message transfer, This is an example of a control means for preventing the caller telephone number from being stored in the incoming call history storage means if it matches the answering machine forwarding destination telephone number.

  FIG. 3 is a flowchart showing a second operation in the answering machine T1.

  It is checked whether the incoming call detection means 11 connected to the telephone line has detected an incoming call signal (S11). If the incoming signal is detected, the caller telephone number data receiving means 15 receives the caller telephone number data sent from the exchange together with the incoming signal when there is no sound between the incoming signals (S12).

  Next, based on the received caller telephone number data, the caller telephone number is displayed on the display means 17 (S13). Then, it is checked whether or not the voice mail forwarding telephone number is registered in the voice mail forwarding telephone number storage means 19 (S14). If the answering machine transfer destination telephone number is registered, it is checked whether the answering machine transfer destination telephone number matches the caller telephone number received at the time of the incoming call (S15).

  If the answering machine transfer destination telephone number matches the caller telephone number, it is checked whether or not the device is currently in an answering machine transfer standby state (S16). If the device is currently in the answering machine transfer standby state, the caller telephone number data processing is terminated without accumulating the caller telephone number in the incoming call history storage means 16. That is, the answering machine transfer destination telephone number is registered in the answering machine transfer destination telephone number storage means 19 (S14), and even if the answering machine transfer destination telephone number matches the caller phone number (S15), the device is currently present. If it is in the answering record transfer standby state (S16), the answering record operation is prioritized and the caller telephone number is not stored in the incoming call history storage means 16.

  On the other hand, if the answering machine transfer destination telephone number is not registered in the answering machine transfer destination telephone number storage means 19 (S14), or if the answering machine transfer destination telephone number does not match the caller telephone number (S15). Or, if the device is not currently in the answering record transfer standby state (S16), the caller telephone number is stored in the incoming call history storage means 16 (S17), and the caller telephone number data processing is terminated.

  FIG. 4 is a flowchart showing a third operation in the answering machine T1.

  First, it is checked whether an incoming signal is detected by the incoming call detection means 11 connected to the telephone line (S21). If the incoming signal is detected, the caller telephone number data receiving means 15 receives the caller telephone number data sent from the exchange when there is no sound between the incoming signals together with the incoming signal (S22). Next, based on the received caller telephone number data, the caller telephone number is displayed on the display means 17 (S23).

  It is checked whether the number of incoming signals detected by the incoming call detection means 11 has reached a predetermined number until answering an answering machine, that is, whether a predetermined number of ringing until answering an answering machine has been reached is checked. (S24).

  When the predetermined number of ringing until the answering machine response is reached, after the incoming call response means 12 closes the line, the recording / reproducing means 13 reproduces the response message to send it to the line, and the response message reproduction ends. Later, a series of voice recording response operations of recording a voice message from the other party and storing it in the message storage unit 14 is started (S25).

  By the way, if the predetermined number of rings until the answering machine response is not reached (S24), the incoming call detection means 11 checks whether the incoming call is finished (S26). When the incoming call ends, the caller telephone number is stored in the incoming call history storage means 16 (S31), and the caller telephone number data processing is ended. If the incoming call has not ended, it is checked whether or not the predetermined number of ringing until the answering machine response is reached (S24). After the answering machine response operation is started, it is checked whether or not a remote operation instruction has been made in order to hear the message stored in the message storage means 14 of the answering machine during the answering machine answering operation (S25). (S27).

  If the remote operation instruction is given, it is checked whether the answering machine transfer destination telephone number is registered in the answering machine transfer destination telephone number storage means 19 (S28). If a remote operation instruction has not been issued (S27), it is checked whether the line has been disconnected by the other party hanging up (S29).

  If the line is disconnected, the caller telephone number is stored in the incoming call history storage means 16 (S31), and the caller telephone number data processing is terminated. If the line is not disconnected (S29), it is checked whether a remote operation instruction has been issued (S27). If the answering machine transfer destination telephone number is registered (S28), it is checked whether the answering machine transfer destination telephone number matches the caller telephone number received at the time of the incoming call (S30).

  If the answering machine transfer destination telephone number matches the caller telephone number, the caller telephone number data processing is terminated without storing the caller telephone number in the incoming call history storage means 16. That is, the answering machine transfer destination telephone number is registered in the answering machine transfer destination telephone number storage means 19 (S28), and if the answering machine transfer destination telephone number matches the caller telephone number (S30), the incoming call history is stored. The CPU 10 prevents the caller telephone number from being stored in the means 16. By doing this, it is possible to avoid deleting meaningful caller phone numbers from the incoming call history when the number of caller phone numbers that can be stored in the incoming call history has reached the upper limit. In addition, even if the number of caller telephone numbers has not reached the upper limit, it is bothersome because the user adds more meaningless operations when searching for incoming calls by accumulating the phone numbers to which the answering machine is forwarded in the incoming call history. I do not feel.

  On the other hand, if the answering machine transfer destination telephone number is not registered in the answering machine transfer destination telephone number storage means 19 (S28), or if the answering machine transfer destination telephone number does not match the caller telephone number (S30). The caller telephone number is stored in the incoming call history storage means 16 (S31), and the caller telephone number data processing is terminated.

That is, the CPU 10 receives an incoming call when the answering machine transfer destination telephone number is registered in the storage means, and the caller telephone number received by the caller telephone number data receiving means matches the answering machine transfer destination telephone number. This is an example of the control means for preventing the caller telephone number from being stored in the incoming call history storage means when the counterpart machine is remotely operated.

  By the way, when a user who owns a telephone is not present, an answering machine that responds to an incoming call from the other party and records the message from the other party in order to accept a message from the other party who has called the telephone is widely spread. Yes.

  The message recorded in the answering machine can be listened to by a message playback instruction by the operation means of the device after the user returns home. In addition, after calling the answering machine from a telephone outside the office and entering a call state, the answering machine can be instructed to play back and listen to the message by remote control using a DTMF signal. it can.

  In addition, by receiving the caller's phone number sent from the exchange via the telephone line when receiving an incoming call and displaying the caller's phone number on the phone, the call is sent before the user answers the incoming call. There is a caller telephone number notification function that can identify the caller. In general, an apparatus that receives a caller telephone number provides a function of storing the received caller telephone number in a storage unit as an incoming call history together with the incoming call date and time.

  The capacity of the storage means for storing the caller phone number as an incoming call history is finite, that is, there is an upper limit on the number of caller phone numbers that can be stored in the incoming call history, so the above number has reached the upper limit In the incoming call history management system, the caller telephone number with the oldest incoming date and time is deleted from the incoming call history and the newly received caller telephone number is stored in the incoming call history. It has been adopted.

  The above method is performed based on the premise that the caller telephone number with the new arrival date and time is more valuable information.

  Here, in the state where the number of caller telephone numbers has reached the upper limit, the user listens to the message recorded in the answering machine, so it is considered that the telephone is called from the outside telephone. When the answering machine receives a caller telephone number by an incoming call from a telephone outside the office, the caller telephone number with the oldest incoming date / time is deleted from the incoming call history and received this time based on the incoming call history management method. Stores the telephone number of the telephone outside the office in the incoming call history.

  The caller phone number notification function is a function to specify the caller by the caller phone number. When there is no caller, there is no message in the answering machine and the caller phone number is stored in the incoming call history. This is a function that makes it possible to make a call again to the caller telephone number.

  However, the number of people who have called the answering machine for the purpose of listening to the messages stored in the answering machine, that is, the caller, can be specified as a very limited person. Further, even if the caller telephone number received by the incoming call is stored in the incoming call history, there is no point in calling the telephone number again.

  Therefore, there is also a problem that a meaningful caller telephone number is deleted from the incoming call history by storing a caller telephone number that is meaningless to be stored in the incoming call history.

  Also, even if the number of caller telephone numbers has not reached the upper limit, if the caller telephone number received by the incoming call for the purpose of listening to the message stored in the answering machine is stored in the incoming call history, the user can There is a problem that annoyance is felt due to an increase in meaningless operations when performing an incoming call history search.

FIG. 5 is a diagram showing an answering machine T2 that is Embodiment 2 of the present invention. The answering machine T2 includes a CPU 20, an incoming call detection means 21, an incoming call response means 22, a recording / playback means 23, and a message storage. Means 24, modem 25, storage means 26, display means 27, operation means 28, and bus B2.

  The CPU 20 controls the device. The incoming call detection means 21 is a means for detecting an incoming signal from a telephone line, and the incoming call response means 22 is a means for responding to an incoming call in the answering machine mode. The recording / reproducing means 23 records and reproduces messages, and the message storage means 24 is means for accumulating response messages and voice messages. The modem 25 detects caller telephone number data receiving means for receiving caller telephone number data sent from the exchange via a telephone line when receiving an incoming call, and DTMF sent when remote operation is performed from the partner machine. DTMF detection means.

  The storage means 26 is also an incoming call history storage means for storing a caller telephone number as an incoming call history, and is a means for storing various states of the apparatus. The display means 27 is a means for displaying the caller telephone number, and the operation means 28 gives various instructions to the apparatus. The bus B2 is a bus for connecting each device / block.

  That is, the CPU 20 is an example of a control unit that prevents storing the caller telephone number in the incoming call in the incoming call history storage unit when a remote operation is received from the partner machine after the incoming call.

  Next, the operation of the answering machine T2 will be described.

  6 and 7 are flowcharts showing a first operation in the answering machine T2.

  First, it is checked whether the incoming call detection means 21 connected to the telephone line has detected an incoming call signal (S41). If the incoming signal is detected, the caller telephone number data received from the exchange at the time of silence between the incoming signals is received by the modem 25 as the caller telephone number data receiving means together with the incoming signal (S42).

  Next, based on the received caller telephone number data, the caller telephone number is displayed on the display means 27 (S43). Then, it is checked whether or not the number of incoming signals detected by the incoming call detecting means 21 has reached a predetermined number until an answering machine response is made (S44). That is, it is checked whether or not the predetermined number of ringing times until the answering machine response is reached. When the predetermined number of rings until answering an answering machine is reached, after the incoming call response means 22 closes the line, the recording / reproducing means 23 reproduces the response message in order to send the response message to the line. After the end, a series of voice recording response operations of recording a voice message from the other party and storing it in the message storage means 24 is started (S45).

  On the other hand, if the predetermined number of rings until the answering record response is not reached (S44), the incoming call detection means 21 checks whether the incoming call is finished (S46), and if the incoming call is finished, the incoming call history storage means. However, the caller telephone number is stored in the storage means 26 (S67), and the caller telephone number data processing is terminated. If the incoming call has not been completed (S46), it is checked whether or not a predetermined number of ringing has been reached until an answering machine is responded (S44).

  After the answering machine response operation is started (S45), it is checked whether or not a remote operation start instruction has been issued in order to hear the message stored in the message storage means 24 of the answering machine during the answering machine answering operation. (S47). The modem 25, which is a DTMF detection means, checks whether or not DTMF # is detected (S47). If DTMF # is detected, the number of bus words that can be input in the bus word input for permitting remote operation is set as a variable. N is set in the storage means (S48), and it is checked whether or not the bus word input is completed (S61).

  On the other hand, if the DTMF # is not detected (S47), it is checked whether or not the line is disconnected by the other party hanging up (S49). If the line is disconnected, the storage means 26 which is also an incoming call history storage means. The caller telephone number is stored in (S67), and the caller telephone number data processing is terminated.

  If the line has not been disconnected (S49), it is checked whether or not the answering record response has timed out (S50). If the answering record response has timed out, the caller telephone is stored in the storage means 26 which is also the incoming call history storage means. The number is accumulated (S67), and the caller telephone number data processing is terminated. If the answering machine response has not timed out (S50), it is checked again whether or not DTMF # indicating a remote operation start instruction has been detected (S47).

  Next, the number of bus word inputs that can be input for permitting remote operation is set in the variable N and stored in the storage means 26 (S48), and then it is checked whether or not the bus word input is completed (S48). S61). When the password input is completed, it is checked whether the input password matches the remote operation permission password held in the storage means 26 (S62). If the password input has not been completed, it is checked whether or not the password input limit time has timed out (S63).

  If the password input limit time is timed out (S63), the caller telephone number is stored in the storage means 26, which is also an incoming call history storage means, in order to end the answering machine response without accepting remote operation (S67). Then, the caller telephone number data processing is terminated.

  If the password input time limit has not timed out (S63), it is checked again whether the password input has been completed (S61). If the entered password matches the password for permitting remote operation stored in the storage means 26 (S62), the remote operation from the partner machine is accepted (S64), and the purpose is to hear the message. Since it is found that the call is an incoming call, the caller telephone number data processing is terminated without accumulating the caller telephone number received by the incoming call in the incoming call history.

  That is, when a remote operation is accepted from the partner machine after an incoming call, the caller telephone number for the incoming call is prevented from being stored in the incoming call history storage means.

  If the input password does not match the remote operation permission password held in the storage means 26 (S62), the password input count N held in the storage means 26 is reduced by one and updated. (S65) It is checked whether or not the password input count N is 0 (S66). If the number N of passwords that can be entered is 0, the caller telephone number is stored in the storage means 26, which is also an incoming call history storage means, in order to end the answering machine response without accepting remote operation (S67). The telephone number data processing is terminated. If the password input count N is not 0 (S66), it is checked again whether the password input is completed (S61).

  8 and 9 are flowcharts showing the second operation in the answering machine T2.

  First, it is checked whether the incoming call detection means 21 connected to the telephone line has detected an incoming call signal (S71). If the incoming signal is detected, the caller telephone number data sent from the exchange when there is no sound between the incoming signals together with the incoming signal is received by the modem 25 which is the caller telephone number data receiving means (S72).

  Next, based on the received caller telephone number data, the caller telephone number is displayed on the display means 27 (S73), and the number of incoming signals detected by the incoming call detection means 21 is predetermined until the answering machine answers. It is checked whether or not the number of ringing has been reached, that is, whether or not the predetermined number of ringing until the answering response is reached (S74). When the predetermined number of ringing times until the answering machine response is reached, after the incoming call response means 22 closes the line, the recording / playback means 23 plays back to send the response message to the line. Then, a series of message recording response operations of recording a voice message from the partner and storing it in the message storage means 24 is started (S75).

  On the other hand, if the predetermined number of rings until the answering machine response is not reached (S74), the incoming call detection means 21 checks whether the incoming call has ended (S76). When the incoming call ends, the caller telephone number is stored in the storage means 26 which is also an incoming call history storage means (S80), and the caller telephone number data processing is ended. If the incoming call has not ended (S76), it is checked whether or not a predetermined number of ringing has been reached until an answering machine is responded (S74).

  After the answering machine response operation is started (S75), it is checked whether a remote operation start instruction has been issued in order to hear the message stored in the message storage means 24 of the answering machine during the answering machine answering operation. In step S77, the modem 25 serving as the DTMF detection means checks whether or not DTMF # has been detected. If # of DTMF is detected, the number of passwords that can be entered for permitting remote operation is set as a variable N and set in the storage means (S78), and it is determined whether or not the password entry is completed (S91). .

  If the DTMF # is not detected (S77), it is checked whether or not the line is disconnected by the other party hanging up (S79). If the line is disconnected, the incoming call history storage means is stored in the storage means 26. The caller telephone number is stored (S80), and the caller telephone number data processing is terminated.

  If the line is not disconnected (S79), it is checked whether or not the answering record response has timed out (S81), and if the answering record response has timed out, the caller telephone is stored in the storage means 26 which is also the incoming call history storage means. The number is accumulated (S80), and the caller telephone number data processing is terminated. If the answering machine response has not timed out (S81), it is checked again whether DTMF # indicating a remote operation start instruction has been detected (S77).

  The number of passwords that can be entered for password entry for permitting remote operation is set as a variable N and set in the storage means (S78), and then it is checked whether the password entry is completed (S91). If the password input is completed, it is checked whether the input password matches the remote operation permission password stored in the storage means 26 (S92). If the password input is not completed, It is checked whether the password input limit time has timed out (S93).

  If the password input limit time is timed out (S93), the caller telephone number data processing is terminated without accumulating the caller telephone number received by the incoming call in the incoming call history. If the password input time limit has not timed out (S93), it is checked again whether the password input has been completed (S91). If the entered password matches the password for permitting remote operation stored in the storage means 26 (S92), the remote operation from the partner machine is accepted (S94), and the caller telephone number received by the incoming call is received. Is not stored in the incoming call history, and the caller telephone number data processing is terminated.

  That is, after the incoming call, when the other party attempts a remote operation, the caller telephone number for the incoming call is prevented from being stored in the incoming call history storage means. That is, the CPU 20 is an example of a control means for preventing the caller telephone number in the incoming call from being stored in the incoming call history storage means when the other party attempts remote operation after the incoming call.
