As one of such functions, a so-called answering machine that automatically responds to an incoming call, sends a response message, records a message from the calling telephone, and reproduces the recorded message based on a predetermined instruction. The telephone function is known. The recorded message is reproduced in response to pressing of a reproduction button provided in the telephone, for example. It is also possible to call the telephone from another telephone to instruct playback and listen to the recorded message on the other telephone. In this case, in order to improve security, a predetermined telephone number is set in advance, When there is an incoming call from another telephone, the telephone number of the other telephone is detected, and when the telephone number matches a preset telephone number, a recorded message is reproduced. Alternatively, a predetermined personal identification number is set in advance, a personal identification number input from another incoming telephone is detected, and a recorded message is reproduced when the personal identification number matches the preset personal identification number.
[0003]
In such a phone, when checking the contents stored by the missed call history function or the answering machine function and making a call again, a writing instrument must be prepared to refrain from the telephone number, etc. Inconvenient. Therefore, a transfer function is known that transfers a call to a predetermined transfer destination when a call is received in the absence.
[0004]
For example, in Japanese Patent Laid-Open No. 5-122301, communication with a caller telephone is transferred to a predetermined transfer destination when the password from the caller telephone detected at the time of the incoming call matches a preset password. A technique for transferring data is disclosed. In JP-A-5-153203 and JP-A-5-153204, a predetermined telephone and a transfer destination telephone are associated with each other in advance, and communication with a caller telephone is associated with the telephone. A technique for transferring to a transfer destination telephone is disclosed. Japanese Patent Application Laid-Open No. 5-153261 discloses a technique in which a transfer destination telephone number is transmitted to a caller telephone so that a call can be made from the caller telephone to the transfer destination telephone. .

FIG. 3 is a flowchart showing the transfer operation of the telephone 1 according to the first embodiment. If it is determined in step a1 that the network control unit 17 has detected an incoming signal and an incoming call has been received, the process proceeds to step a2, where the destination telephone number included in the detected incoming signal is detected by the destination detecting unit 7, and the incoming call is detected. The telephone number and the specific telephone number stored in the specific telephone number storage table of the various setting storage unit 13 are collated to determine whether the incoming telephone number is the specific telephone number. Such a telephone number verification and determination operation is executed by the control unit 2. When the telephone numbers match each other, the process proceeds to step a4, and when they do not match, the process proceeds to step a3.
[0066]
In step a3 where the telephone numbers do not match, the detected incoming telephone number is stored in the incoming telephone number storage table of the other party telephone number storage unit 12, and the operation is terminated.
[0067]
In step a4 in which the telephone numbers coincide with each other, the control unit 2 determines whether or not the missed call telephone number is stored, that is, whether or not the received telephone number is already stored in the incoming call number storage table. When it is stored, the process proceeds to step a5. When it is not stored, the transfer operation is not performed and the operation is terminated as it is.
[0068]
In step a5 when the incoming telephone number is stored, the line is connected to the one telephone that has been received via the telephone line network, and the telephone call is established. In step a6, a call established by performing a hooking operation is put on hold. Further, in step a7, the incoming telephone number stored in the incoming telephone number storage table is called and the other telephone is called. Further, in step a8, the line connected to the one telephone is cut off, and the transfer operation is terminated. In this way, by changing the connection state of the line through the telephone line network, it is possible to establish a communication path between the one telephone and the other telephone. Such a transfer operation is controlled and executed by the control unit 2. Note that the transfer method is not limited to the above-described method, and is appropriately determined according to the network form.
[0069]
FIG. 4 is a sequence showing an example of the transfer operation of the telephone 1 according to the first embodiment. According to the telephone 1, when there is a call from any telephone B that is not a specific telephone to the telephone 1 in the absence of an operator, the telephone number of the telephone B is stored in the incoming telephone number storage table.

Note that a hold sound may be sent in place of the message. Further, following the message, the telephone network sends a ring back tone (RBT) to the telephone A while the telephone 1 is calling the telephone B.
[0071]
As described above, according to the first embodiment, for example, when the operator who has gone out operates the specific telephone A, the telephone 1 is called from any telephone B other than the specific telephone A. When a call is made from the specific telephone set A to the telephone set 1, the telephone set B is automatically called, and a telephone call between the telephone sets A and B becomes possible by the response of the telephone set B.
[0072]
Therefore, it is not necessary for the operator who is out of the office to perform a troublesome operation for confirming whether or not there is a missed call, etc., and it is not necessary to prepare a writing instrument for that purpose, so that the operator of the telephone B that has responded can make a call. it can. Therefore, operability is significantly improved.
[0073]
Note that it may be determined whether only a call from a specific telephone set A is used by using a personal identification number instead of the telephone number. That is, a password is registered in advance in the telephone 1, and the other terminal device is set to input the password when receiving a call, and a transfer operation is executed when the passwords match.
[0074]
FIG. 5 is a sequence showing an example of the transfer operation of the telephone 1 according to the second embodiment. After a telephone is connected from the specific telephone A to the telephone 1 and a line is established between the telephones 1 and A to establish a call, in the second embodiment, in particular, a message indicating the telephone B to be called, for example, “telephone B The message “Missed call from” was sent to telephone A. The control unit 2 reproduces the message using a message recording / reproduction unit 15 corresponding to a message transmission means, and transmits the message to the telephone line network via the network control unit 17.
[0075]
After sending out the message, the telephone call is put on hold and the telephone set 1 calls the telephone set B as in the first embodiment. When there is a response at the telephone B, the line between the telephones A and B is connected to establish a call.
[0076]
As described above, according to the second embodiment, a message indicating the telephone B called to the specific telephone A can be sent, and the operator who operates the telephone A can grasp the transfer destination. As a result, when the telephone B responds, the operator of the telephone A can perform an appropriate response, and convenience is improved.
[0077]
FIG. 6 is a flowchart showing the transfer operation of the telephone 1 according to the third embodiment. This flowchart is obtained by adding steps a9 to a12 to the flowchart of FIG. 3, and a description of similar steps will be omitted.
[0078]
If the incoming telephone number matches the specific telephone number, the telephone number of the missed incoming call is stored, and if a call is established by connecting the line in step a5, the process proceeds to step a9. In step a9, the timer 11 is set and time measurement is started. In step a 10, a message indicating the telephone B to be called is reproduced by the message recording / reproducing unit 15 and sent to the telephone A via the network control unit 17.
[0079]
In step a11, the control unit 2 determines whether or not the partner end-call detection unit 8 has detected an end-call signal indicating the end of the call between the telephones 1 and A, for example, a busy tone (BT). If detected, the process proceeds to step a8. If not detected, the process proceeds to step a12. In step a12, the control unit 2 determines whether or not the time measured by the timer 11 exceeds a predetermined time. When it exceeds, the process proceeds to step a6, and when it does not exceed, the process returns to step a11.
[0080]
FIG. 7 is a sequence showing an example of the transfer operation of the telephone 1 according to the third embodiment. After a telephone call is made from the specific telephone set A to the telephone set 1 and a call is established by connecting the lines between the telephone sets 1 and A, in the third embodiment, in particular, in a predetermined time (in the end-of-call detection section in FIG. 7). A message indicating the telephone B to be called is sent to the telephone A. When the telephone A enters the on-hook state and detects a busy tone from the telephone line network in the end-call detection section, the line between the telephones 1 and A is blocked to cut off the call, and the telephone 1 performs the transfer operation. Interrupt. When no busy tone is detected within the end-of-call detection section, a transfer operation is performed in the same manner as in the first embodiment.
[0081]
As described above, according to the third embodiment, when the operator of the telephone set A listens to the message from the telephone set 1, determines that the transfer is unnecessary and blocks the line by blocking the line, the transfer operation of the telephone set 1 is performed. Interrupt. Therefore, it is possible to prevent a call from being transferred to an unnecessary party.
[0082]
FIG. 8 is a flowchart showing the transfer operation of the telephone 1 according to the fourth embodiment. This flowchart is obtained by adding step a13 to the flowchart of FIG. 6, and description of similar steps is omitted. When the partner end call detection unit 8 detects a busy tone indicating the end of the call between the telephones 1 and A in step a11, the process proceeds to step a13, and the control unit 2 erases the incoming telephone number stored in the incoming telephone number storage table. . Such a telephone number erasing operation is executed by the control unit 2. When the incoming telephone number is deleted, the process proceeds to step a8.
[0083]
As described above, according to the fourth embodiment, when the operator of the specific telephone set A listens to the message from the telephone set 1 and determines that the transfer is unnecessary and interrupts the call, the telephone set 1 interrupts the transfer operation, Delete the telephone number of telephone B. Therefore, when a call is subsequently made from the specific telephone set A to the telephone set 1, it is not transferred to the telephone set B that has already been determined to be unnecessary. In addition, since the message indicating the transfer to the telephone set B is not transmitted, the call charge can be reduced.

【The invention's effect】
As described above, according to the present invention, a telephone call is made from one terminal device specified by a telephone number to automatically call the other terminal device. Communication between devices becomes possible. On the other hand, since the operator of the terminal device does not need to perform a troublesome operation for confirming whether a telephone call has been made on the telephone, and does not need to prepare a writing instrument, the operability is remarkably improved.
In addition, a telephone call is made from one terminal device specified by a telephone number or terminal identification information, and a desired other terminal device is selected from a plurality of other terminal devices, and the other terminal device is called. Therefore, a call between one terminal device and the other terminal device is enabled by the response of the other terminal device.
[0165]
Further, according to the present invention, the telephone number of the other terminal device selected and transferred from among the plurality of other terminal devices previously received is deleted, so that the telephone is called from the one terminal device next time. Therefore, it is no longer transferred to the other terminal device that has been transferred once, so unnecessary transfer operation to the other terminal device can be eliminated, the call time can be shortened, and the call charge can be reduced for convenience. Can be improved.
[0166]
Further, according to the present invention, it is possible to control the transfer operation without deleting the telephone number by the transfer status information for the plurality of other terminal devices.
[0167]
According to the present invention, since the telephone number is not deleted when the other terminal device is in a call, the other terminal device that is in a call when the telephone is called from the one terminal device next time A desired other terminal device can be selected and transferred from the other terminal devices.
[0168]
Further, according to the present invention, the transfer operation can be controlled without erasing the telephone number by the transfer status information including the call status information for the plurality of other terminal devices.
[0169]
Further, according to the present invention, when it is detected that the other terminal device of the transfer destination is busy, a message indicating that the other terminal device is busy is sent to the one terminal device. Therefore, the operator who operates one terminal device can grasp that the other terminal device of the transfer destination is busy.
[0170]
According to the present invention, when it is detected that the other terminal device of the transfer destination is busy, the other terminal device of a different transfer destination is selected again and transferred to the reselected other terminal device. Therefore, the transfer operation to the plurality of other terminal devices can be repeatedly performed by one call of the telephone by the one terminal device, and excellent operability can be obtained.
[0171]
Further, according to the present invention, when it is detected that the other terminal device of the transfer destination is busy, the hold is released and the audio signal from the one terminal device is recorded. A message from the operator to the operator of the other terminal device can be recorded on the telephone.
[0172]
Further, according to the present invention, the transfer operation to the other terminal device that was in a call at the time of transfer is executed again, and when there is a response at the other terminal device, the recorded voice signal is played back to the other terminal device. Therefore, a message from the operator of the one terminal device to the operator of the other terminal device can be easily sent by only one call from the one terminal device.
[0173]
Also, according to the present invention, when a call is made from the other terminal device that was busy during the transfer, the recorded voice signal is reproduced and sent to the other terminal device. A message from the operator to the operator of the other terminal device can be easily transmitted with only one call from the one terminal device.
