Description

[Detailed description of the invention] [Technical field] The present invention relates to an electronic TTI notebook device.

[Prior Art] For example, when having a conversation using a voice terminal device (telephone terminal) using a line network, if the other party is not present, the conversation with the other party cannot be established.

When a conversation with the other party cannot be established in this way, for example, if the other party is sharing the telephone terminal with another person and the other person can pick up the telephone terminal,
Since the user can request that person to send a message to the other party, the user can have the conversation that the caller intended. Furthermore, if the other person responds to the caller with the time when the conversation partner will return, the user can continue the conversation with the intended party by calling again after that time.

However, since a person other than the intended person of the caller has to talk to the caller, people who do not need to talk to the caller may be interrupted from their work, which is inconvenient.

Furthermore, if the person on the other end of the conversation uses the telephone terminal for exclusive use, it is not possible to even request a message from another person, which is very inconvenient for the person making the call.

Now, in recent years, the functions of private branch exchange equipment have become extremely rich, and the functions of private branch exchange equipment have become extremely rich. In the case of a call between J and J, when the other party is absent, a message indicating that the call was received while the other party was absent is displayed on the other party's telephone terminal, and when the other party returns, the caller is automatically connected to the caller's telephone terminal. There are some that have the ability to do this.

With such a function, even if the telephone terminal is a dedicated one, it is very convenient because it automatically connects you to a caller when you are absent.

However, if you are automatically connected to a person who called you when you were away, it is not possible to identify the person you are talking to if the phone terminal is shared by multiple people, so you may not be able to carry out the conversation that the caller intended. It cannot be done and is not recommended. Furthermore, even if the telephone terminal is a dedicated one, it is not possible to confirm who is calling when the user is absent, which is an undesirable inconvenience.

[Purpose] The present invention has been made in order to solve the above-mentioned disadvantages of the prior art, and allows the conversation intended by the caller to be carried out reliably and without the intervention of people who are not involved in the conversation. The purpose of this invention is to provide an electronic telephone directory device that will never be lost.

[Configuration] The present invention stores personal information consisting of at least each user's name, the line number in use, and caller information in the case of an incoming call when the user is absent, and When the user returns, if the sender information in the user's personal information is validly stored, the user will be notified by voice of the caller's name, and the caller's name will be notified by voice. automatically connects to the terminal device.

Further, the switch 24 connects the multi-function telephone terminal FT1 to the communication path 1.
Alternatively, the switch 25 switches and connects the multi-function telephone terminal FT1 connected via the modem 23 or switch 24 to the terminal control section 8, and these switches 24
, 25 are switched and controlled by the control section 22.

Note that the line circuit 3 also has a similar configuration to this line circuit LC1.

Now, the control unit 4 in the private branch exchange PBX manages various types of information used for the electronic telephone directory function in the formats shown in FIGS. 4(a) to 4(e).

Among these pieces of information, the personal information ID is the private branch exchange device PB.
This is information about each user using extension X, and the extension management table TI is information indicating the usage status of multifunction telephone terminals FTz to FTn in the extension.

Personal information ID includes the person's personal name DN, the person's affiliation Do,
Telephone number (extension number in this case) TN, Fax number FN indicating the extension number of the nearest facsimile machine, Temporary telephone number TT indicating the extension number (or external number) of your temporary destination, and whether you are at your seat or not. Ararasu presence/absence data SN, call arrival time period A.
B, and an incoming call information CD that informs you that there was an incoming call when you were absent, and is stored in the storage device 6. Note that the information is read out from the storage device 6 by the control unit 4 as appropriate.

In addition, the personal name DN is a personal name DNd that is a direct expression consisting of a string of characters that make up the name (kanji, kana, numbers, alphabets, symbols, etc.), and the alphabet of the letters that make up the name are arranged in the following order: It consists of the indirect expression of the personal name DNm obtained when converted into a number using the method.

The code information that forms this indirect expression is created by assigning an alphabet to each number on a button dial (for example, the numeric keys of multi-function telephone terminals FT1 to FTn) in the correspondence shown in Fig. 5, and forming a name in Roman letters. It is a coded sequence of numbers when the alphabets are selected in that order.

In other words, for example, the surname "Furukawa" is rFURUKA.
It is written in romaji as IAJ, so if you follow the alphabet and number assignment method described above, it will be r38785292.
It is converted into a number string J, and this is stored as the personal name DN+o.

The belonging DO also includes a direct expression belonging DOd and an indirect expression belonging DOm.

In addition, as data for indirect expression, in the case of personal name DNm, the employee number etc. set by the company etc. for the individual can be used, and in the case of affiliation DOm, the identification set within the company etc. can be used. Numbers etc. can be registered.

The incoming call information CD is a series of data consisting of caller information, caller telephone number, and valid/invalid information for each incoming call when the user is absent.

The extension management table TI is for each multi-function telephone terminal F.
For T1 to FTn, individual/multiple information is stored as to whether it is used by an individual or by multiple people, and if it is used by an individual, the name information is stored. and affiliation information are stored in direct representation. As the terminal identification information, data indicating the type of each of the multifunction telephone terminals FT1 to FTn is stored.

In addition, among the personal information IO, data other than the temporary telephone number TT and presence/absence data SN is directly generated ((recorded) from the administrator terminal device 2, and a special password etc. set in the system is input. It will not be updated or deleted unless it is registered.Also, at the time of registration, the temporary telephone number TT field is set to an invalid state (for example, all digits are FF (hexadecimal)), and the presence/absence data SN is ”.Passwords may be set for each individual, in which case personal information about themselves (It) may be set for each individual.
You can update it as you like.

Further, in the same way as the temporary telephone number TT for the telephone number k) 1'N, it is also possible to set a -.times FAX number for the FAX number 1.N.

Similarly, the extension management table TI is also directly registered by the administrator terminal device 2.

With the above configuration, for example, when making a call to a desired destination from the multi-function telephone terminal Togo 1, the operator first inputs the recipient's personal name in indirect expression from the numeric keypad of the multi-function telephone terminal Turn on the book key.

As a result, the multi-function telephone terminal FT+ has line circuit LC.
The dialer 13 transmits a DTMF l--on signal corresponding to the telephone directory key, and the input personal name is transmitted via the modem 14. After transmitting the personal name, the network control device 11 is connected to the handset 12.
Switch to the side.

In the initial state, the line circuit LC1 connects the switch 24 to the switch 25 side and the switch 25 to the modem 23 side.
When it is detected that the TMF tone is that of a telephone directory key, the switch 25 is switched to the switch 24 side, and the information of the personal name outputted from the multifunction telephone terminal FT1 thereafter is outputted to the terminal control section 5, and then Then switch 25 to the modem 23 side.

The terminal control unit 5 transfers the personal name information output from the line circuit 14C1 to the control unit 4.

Based on the personal name information transferred from the terminal control unit 5, the control unit 4 generates a personal information ID in which a personal name DNm in indirect expression that is the same as the transferred personal name in indirect expression is registered.
is searched and read from the storage device 6. Next, it is determined whether the presence/absence data SN of the personal information IO that has been read out is set to the pillar state, and if it is set to the pillar state, the old value is further displayed in the call availability time. Determine whether it is a time when you can receive calls.

If the destination can be reached by 11, it is determined whether valid data is stored in the temporary telephone number TT of the personal destination information CD, and if the temporary telephone number TT is valid, the temporary telephone number TT and, if the temporary telephone number TT is invalid, the telephone number TN, and informs the terminal control unit 5 that the multifunction telephone terminal FT+ can make a call.
At the same time, through call path 1, the multi-function telephone terminal ['Tl] is sent to the temporary telephone number
Connect to T or the extension of telephone number TN. Furthermore, it instructs the terminal control section 5 to connect the extension corresponding to the temporary telephone number TT or telephone number TN read out at that time to the telephone line 1.

As a result, the terminal control unit 5 notifies the line circuit LCI to connect the multifunction telephone terminal FT+ to the call path l, and also connects the line circuits LC2 to LCn corresponding to the destination extension specified by the control unit 4. A command is given to connect to communication path 1.

As a result, the line circuit LCI switches and connects the switch 24 to the communication path 1 side, and also switches and connects the switch 25 to the modem 23 side, so that the multifunction telephone terminal FTi is connected to the communication path 1.

On the other hand, since the line circuits LC2 to LC ports of the destination extensions switch the switch 24 to the communication path 1 side and connect, the multifunction telephone terminals FT2 to FTn of the destination are also connected to the communication path 1,
As a result, it is possible to connect to the destination telephone terminal and make a call.

In addition, if the destination cannot receive calls, the control unit 4
commands the terminal control section 5 to connect the multifunction telephone terminal FT1 to the communication path 1, and also connects the line circuit LCz and the voice response device 7 via the communication path 1.

As a result, the terminal control unit 5 notifies the multi-function telephone terminal FTl to be connected to the communication path 1, and thereby the line circuit LC1 switches the switch 24 to the communication path 1 side and connects the voice response device. 7 and multifunctional telephone terminal F
``[1 is connected via communication path 1.

Also, at this time, the model lz2:3 of the line circuit LC1
remains connected to the terminal control unit 5.

In this state, the control unit 4 uses the voice response device 7 to send a voice message to the operator of the multifunction telephone terminal F1'l, for example, saying, "The specified destination is unavailable."

At this time, the content of the extension management table TI of the multi-function telephone terminals F and T+ used by the caller is referred to, and if the multi-function telephone terminal FT+ is for personal use, the extension management table TI is checked. The name information in table TI is stored in the caller information column of the incoming call information CD of the destination's personal information ID, and the extension number of the multi-function telephone terminal FT1 is stored in the caller telephone number column, and the corresponding enable/disable Set information to valid state.

If the multifunctional telephone terminal Togo 1 is used by multiple people, the voice response device 7 will display, for example, ``Please enter your personal name and phone number manually.'' ] Send a voice message.

As a result, DTMF tones are output from the multi-function telephone terminal Togo 1 in accordance with the order of keys operated by the operator, which are discriminated by the control unit 22 of the line circuit LC1 and converted into corresponding code information. The code information is output to the terminal control unit 5 via the modem 23 and further transferred to the control unit 4.

Thereby, the control unit 4 stores the transferred personal name and telephone number in the caller information column and caller telephone number column of the incoming call information CD of the destination's personal information ID, and
Set invalid information to valid state.

At this time, the personal information ID having the notified personal name and the personal name DNm in indirect indirect expression is searched and read from the storage device 6, and the personal name DN in direct expression of the personal information In is retrieved from the storage device 6 and read out.
d may be stored in the sender information column of the incoming call information CD of the destination's personal information In.

After completing the setting of the incoming call information CD in this way, the control unit 4 instructs the communication path 1 to disconnect the line circuit LCI and the voice response device 7, and also instructs the terminal control unit 5 to disconnect the line circuit LC1 from the line circuit LC1. command to disconnect communication path 1 from communication path 1.

As a result, the terminal control unit 5 causes the line circuit 1. C1 is notified, thereby causing the line circuit LCI to switch and connect the switch 24 to the switch 25 side.

Furthermore, the control unit 4 instructs the terminal control unit 5 to notify the current destination that there has been an incoming call in the absence of a call.

As a result, the terminal control unit 5 instructs the line circuits LC2 to LCn corresponding to the destination extension specified by the control unit 4 to switch the multifunction telephone terminals F1'2 to FTn to the terminal control unit 5 side, Therefore, any of the line circuits LC2-L, Cn connects the switch 25 to the switch 24 side to connect the multifunction telephone terminals Togo2-FTn to the terminal control section 5.

In this state, the terminal control unit 5 controls the multi-function telephone terminals FT2 to F.
The multifunction telephone terminals FT2 to FTn display the fact that the call was received in the absence. For example, a lamp is turned on to indicate an incoming missed call.

In this way, if the destination is not present, the incoming call will be displayed on the multi-function telephone terminal r"r 2~FTn (FT+~F
Tn) and the personal information ID of the destination.
Information regarding the caller is stored in the incoming call information CD column. Further, when there are incoming calls from multiple callers, information regarding each caller is stored in the incoming call information CD column of the destination's personal information ID.

Next, when the recipient who was absent returns, and the multi-function telephone terminals FT2 to FTn used by that person display that there was an incoming missed call, first, the multi-function telephone terminal FT2 is displayed. ~ Pick up the FTn handset 12, turn on the telephone directory key, and enter your personal name.

As a result, the control unit 4 is notified of the individual's name in the same manner as described above. Then, the control unit 4 first instructs the multifunction telephone terminals FT2 to FTn and the voice response device 7 to be connected to the communication path l, and in the same manner as described above, the terminal control unit 5
The multi-function telephone terminals FT2 to FTn are connected to the communication path 1 by the following steps.

Next, the control unit 4 receives personal information I corresponding to the received personal name.
O is searched and read from the storage device 6, and its personal information I
The valid caller information from the incoming call information CD column of D is output to the voice response device 7, and the personal name of the caller is notified to the addressee by voice. At this time, the presence/absence information SN of the personal information TO is set to the pillar state.

When this notification is finished, the caller corresponding to the caller information (the extension corresponding to the F1 party telephone number) is switched from the voice response device 7 to the call path 1, and the call is connected.
This causes the addressee to automatically call the caller.

In addition, at this time, after notifying the caller's personal name by voice, for example, ``Do you want to connect to the caller?'' When connecting, input dial 1. When not connecting, input dial 2. It is also possible to send a voice message to the recipient and have the recipient automatically call the caller only when Dial 1 is operated at that time.

In this way, if you automatically call the recipient and the caller,
Valid/invalid information regarding the caller connected at that time is set to an invalid state.

Then, when a call from the destination person to one caller ends, if valid caller information is stored in the paulownia of the incoming call information CD for that destination, the same process as described above is executed for that caller information. As a result, all callers who are absent are automatically called by the recipient.

Next, a case will be described in which the operator updates his own personal information ID.

For example, when considering updating from the multi-function telephone terminal FTI, the operator first turns on the telephone directory operation key and then turns on the telephone directory key.

As a result, the multifunction telephone terminal FTl is connected to the control unit 4 via the line circuit LC1 and the terminal control unit 8 in the same way as described above.
connected to. Next, the multifunction telephone terminal FTl switches the network control device 11 to the modem 14 side, transmits a terminal command to the control section 4 via the modem 14, and thereafter operates as a terminal device for the control section 4, and operates the terminal. Data input from the keys is transferred to the control section 4, and response data or echo back data from the control section 4 is displayed on the display. Note that when operating as a terminal device of the control section 4 in this manner, data exchange between the multifunction telephone terminal FT1 and the control section 4 is performed via the modem 14.

When the control unit 4 receives the terminal command from the multi-function telephone terminal FT1, it first requests the operator to input the personal name in indirect expression, and when it is input, it inputs the input indirect expression. Personal name with the same indirect expression as the personal name 1)
The personal information ID in which NIll is registered is searched from the storage device 6, and the personal information ID is read into the memory 2.

At this time, it is also possible to request that the affiliation be input in indirect expression. Furthermore, when a password has been set for an individual, it is also possible to request the password to be input immediately after inputting the individual's name using indirect expression, and to display the operation menu only when the correct password is input. If the correct password is not entered at that time, the line may be disconnected at that point.

For example, [1. Presence/absence change 2. Temporary phone number manual 3. Others 4. Exit” operation menu-2
0= is displayed on the multifunction telephone terminal FT1, and the operator is prompted to select the desired operation.

Here, if the operator selects "1. Presence/absence change", the control unit 4 first displays the currently set presence/absence data SN and asks the operator whether or not to change it. When the operator inputs a change to this (for example, by turning on "1" on the numeric keypad), the content of the presence/absence data SN is changed, the result is displayed, and the operator is further notified. After that, the first operation menu will be displayed. At this time, if the presence/absence data SN is changed from the "V absent" state to the "1 presence" state, the control unit 4 uses the temporary telephone number TT which is in the valid state.
change to disabled state.

In addition, when the operator selects "2. Temporary telephone number manually", the temporary telephone number input mode is set, and the key data entered by the operator using the operation keys is temporarily stored as a temporary telephone number, and the input data is echoed. Back up. Then, when the operator notifies the completion of temporary telephone number input, the data entered so far is stored in the personal information IO as the temporary telephone number TT, and
Display the first operation menu.

Normally, when the presence/absence data SN is changed from "present" to "absent", this temporary telephone number is also input.

Note that the temporary telephone number may be a speed dial telephone number set in the multifunction telephone terminal FTI, or may be either an extension number or an external number.

When "3. Others" is selected from the operation menu, a mode for changing other personal information IDs is selected, and the control unit 4 first enters the password set in the system (or the password set for the individual). password).

When the correct password is manually entered here, the control unit 4
Displays a submenu for selecting the item to be changed []. When one item is selected from the submenu, the current settings for that item are displayed, the user is asked whether or not to change them, and if the item is to be changed, the process moves on to make the changes. When finished or if no changes are made, display the submenu.

This submenu includes an item for terminating the work in "3. Others", and upon completion, the first operation menu is displayed. Furthermore, if the correct password is not entered before the submenu is displayed, the display returns to the initial operation menu display state.

Then, when "4. Exit" is selected from the operation menu, the control section 4 ends this operation mode, returns the multifunction telephone terminal FTI to its original state, and at the same time, the terminal control section 5 causes the multifunction telephone terminal FTI to return to its original state. Disconnect from terminal FTI.

Other contents of the operation menu include, for example, if your personal information ID includes a temporary fax number, you can add an item to enter this temporary fax number.
In that case, when the presence/absence data SN is changed from the "absent" state to the "present" state, the temporary FAX number may be automatically set to an invalid state.

Also, as a matter of course, the operating procedure for updating the personal information ID is not limited to two consecutive procedures.

It should be noted that the deletion of the personal information 0 can be performed by each individual at his/her discretion, but the personal information ID may also be deleted only by the administrator terminal device 2, as in the case of registration.

By the way, in the embodiment described above, the electronic telephone directory function is realized as one function of the private branch exchange device PBX, but the electronic telephone directory function can also be realized by a separate device.

Next, other embodiments of the present invention will be described.

FIG. 6 schematically shows a private branch exchange device to which an electronic telephone directory device according to another embodiment of the present invention is applied. In this figure, the same parts and corresponding parts as in FIG. 1 are denoted by the same reference numerals, and the explanation thereof will be omitted.

In the figure, the outside line side of the private branch exchange $1PBXa is connected to the public network (subscriber network) via line PL.

In addition, the extension has multiple multi-function telephone terminals FTI to FTn,
and electronic telephone directory device BK are connected.

Therefore, the private branch exchange @PBX connects the terminal devices connected to the extensions to each other, and connects the terminal devices connected to the extensions to the line PL, which is an outside line, as appropriate.

The electronic telephone directory device BK is connected to the private branch exchange device P[3Xa via a plurality of extensions,
An administrator terminal device 2 and a relay stand 9 are connected to K, an example of which is shown in FIG.

In the figure, a CPU (central processing unit) 31 is for controlling this electronic telephone directory device BK, and a memory 32 that constitutes a system memory and a work memory, and stores control data and various file data. It is equipped with a magnetic storage device 33 for these CPUs 31,
Memory 32 and magnetic storage device 33 are connected via system bus SB.

Further, the administrator terminal device 2 and the relay stand 9 are connected to the interface circuits 34 and 35 system bus SB.

In addition, the extension of the private branch exchange device PBXa is equipped with communication control units CFt to CFt for connecting to the multifunction telephone terminals FTz-FTn.
These communication control units C are connected via CFn.
Fl-CFn is connected to system bus Sn via interface circuits IFt-TFn.

An example of communication control units CFI to CFn is shown in FIG.

In the figure, a communication control unit CFl (~CFn) is a network control bag [141] equipped with an automatic call/receiver function for connecting to a private branch exchange device PBXa, and a bush dial tone output from a multifunction telephone terminal FT+~FTn. DTFM detection unit 42 for detecting the DTFM, modem 43 for exchanging data with the multifunction telephone terminals FT1 to FTn, and voice synthesis for outputting the message from the CPU 31 as voice to the multifunction telephone terminals FT1 to FTn. Section 44, net control bag W4

It is composed of an interface circuit 46 for exchanging data between the CPU 31 and the CPU 31.

Therefore, when a call is made from the multifunction telephone terminals FTi to FTn and connected to the electronic telephone directory device BK through the private branch exchange device I) port x8, the communication control units CF1 to CFn are selected by the private branch exchange device PBXa.

This is an application of the group transfer function of the private branch exchange device PBXa, that is, the communication control units CF1 to CFn
If multiple extensions connected to the FTI-FTn are registered in advance in the private branch exchange PBXa so as to form one group, the multi-function telephone terminal FTI-FTn can connect to the group of the communication control unit CF, -CFn. By simply specifying the corresponding extension number to the private branch exchange PBXa, communication control unit C
The vacant one among F1 to CFn is private branch exchange PB.
It is automatically selected and connected by Xa.

With the above configuration, for example, from one of the multi-function telephone terminals FTI to FTn (in this case, from the multi-function telephone terminal FT1)
When making a call to a desired destination, the operator first inputs the destination's personal name in indirect expression using the numeric keys of the multi-function telephone terminal FT1, and then turns on the telephone directory key.

As a result, the multifunction telephone terminal FTI is connected to the private branch exchange PB.
It connects with Xa and sends the extension number corresponding to the group of communication control units CF1 to CFn. In response, the private branch exchange device PBXa selects one of the vacant communication control units CF] to CFn.
The multifunction telephone terminal FTl is connected to the communication control units CF1 to CFn.

When the connection with the communication control unit CF+-Cl”n is completed, the multifunction telephone terminal FTl switches the network control device 11 to the modem 14 side, and sends the indirect expression personal name inputted by the operator to the connection request command (predetermined). (consisting of code information) is then sent to the electronic telephone directory device BK via the modem 14.

As a result, the electronic telephone directory device BK first identifies the connection request command code included in the received data, and determines that the data following it is the indirect expression of the personal name.

Then, the personal information ID in which the indirect expression personal name 1) N+11, which is the same as the transferred indirect expression personal name, is registered.
is searched from the magnetic storage bag @33 and its personal information ID is read into the memory 32. Next, the read personal information I
Identifies whether D's presence/absence data SN is set to the pillar state, and if it is set to the pillar state, the time period during which calls can be received is shown in All = 28-. Determine whether or not.

If the destination can receive calls, it is determined whether valid data is stored in the temporary phone number TT of the personal information ID, and if the temporary phone number TT is valid, the temporary phone number TT is If the temporary telephone number TT is invalid, the telephone number TN is read, and the private branch exchange PBXa is commanded to connect the multifunction telephone terminal FTI to the read temporary telephone number TT or telephone number TN. At the same time, the multifunction telephone terminal FT1 is commanded to switch to the handset 12 side.

As a result, the private branch exchange device PBXa is connected to the multifunction telephone terminal F.
At the same time as cutting off the connection between Tz and the electronic telephone directory device BK, the multi-function telephone terminal FT1 is temporarily put on hold, and the multi-function telephone terminal FTI is temporarily set to the telephone number TT or the telephone number T.
It connects to multi-function telephone terminal devices FT2 to FTn corresponding to N. In addition, the multi-function telephone terminal FT1 has an electronic telephone directory device B.
In accordance with the command from K, the network control device 11 is switched to the handset 12 side, and thereby the user can talk to the specified individual.

Also, if the destination cannot receive calls, CPU3
1 instructs the multi-function telephone terminal FT+ to switch to the handset 12 side, and also sends a command to the communication control units CF and -C.
The voice synthesis unit 44 of the Fn sends a message to the operator of the multi-function telephone terminal FTl, for example, ``The specified destination is unavailable.''

” will be sent a voice message.

Then, in the same manner as in the two consecutive embodiments, the caller's personal name and telephone number list) are transferred to the recipient's personal information I+1 incoming call information C.
D is stored in the caller information field and caller (PI party telephone number field), and the corresponding valid/invalid information is set to the valid state.

However, in this case, if the multifunctional telephone terminal Togol is used by multiple people, in response to a voice message output from the voice synthesis section 44, such as "Please enter your personal name and telephone number," The DTMFI signals output to the multi-function telephone terminal FTI or I in accordance with the order of keys operated by the operator are the DTs of the communication control units CFl-CFn.
It is detected by the MF detection section 42, determined by the control section 45, and notified to the CPU 31.

After completing the setting of the incoming call information CD in this way, the CP
U31 causes the communication control units CFI to CFn to disconnect from the private branch exchange device PBXa. Additionally, the multifunction telephone terminal FTz also disconnects from the private branch exchange device P B X a.

Next, the CPU 31 selects the communication control unit C that is vacant at that time.
A call is made to the current destination using F1 to CFn, and the corresponding multifunction telephone terminals FT2 to FTn are notified that the call has been received while the user is absent. Displays that there is an incoming call.

If the recipient who was absent returns and the multi-function telephone terminals FT2 to FTn used are displayed to indicate that there was a missed call, the handset 12 of the multi-functional telephone terminals FT2 to FTn is picked up and the telephone directory is displayed. When you turn on the key and enter your personal name, the CPU 31
will be notified of the individual's name.

Next, the CPU 31 retrieves the personal information ID corresponding to the accepted personal name from the magnetic storage device 33, reads it into the memory 42, and reads it from the incoming call information CD column of the personal information ID = 31
- Output the valid caller information to the speech synthesis section 44 and notify the addressee of the sender's personal name in voice.

When this notification is finished, the private branch exchange (PBXa) is instructed to connect the extension of the destination at that time to the extension corresponding to the caller telephone number corresponding to the caller information. As a result, a call is automatically placed from the addressee to the caller. Also, the communication control unit c1 that was connected at that time
'1 to CFn are disconnected.

Thereafter, by the same process as in the embodiment described above, all callers who are absent are automatically made to call from the destination person.

As an operating procedure, it is also possible to first turn on the telephone directory key, connect to the electronic telephone directory device 11, and then input the name of the individual of the destination in indirect expression. In this case, since the electronic telephone directory device 18 does not send predetermined data after the multifunction telephone terminal FTt is connected, it can be determined that the operator has directly connected.

Incidentally, although analog lines are used in each of the embodiments described above, the present invention can also be applied to cases where digital lines are used. In that case, a modem is not required.

Furthermore, in each of the embodiments described above, the electronic telephone directory device according to the present invention is applied to a private branch exchange, but it is also possible to connect this electronic telephone directory device to a wide area network such as a public network to provide one of the services of the public network. It can also be made into one function.

In each of the embodiments described above, the functions of the electronic telephone directory device are used for communication between extension lines, but the functions of the electronic telephone directory device can also be made usable by a terminal device connected to an outside line.

Also, when connecting an outside line to an extension line using a relay stand,
The functions described above can be used. In that case, the contents of the incoming call information can be input directly from the relay console.

[Effect] As explained below, the personal information of each user of the line network, consisting of at least the user's name, the line number they are using, and caller information in the case of an incoming call while they are not available, is collected. When the absent user returns, if the caller information in the user's personal information is effectively stored, the user will be notified by voice of the caller's name and Since the communication is automatically connected to the terminal device of the caller (d party), it is possible to reliably establish the conversation that the caller (f1 party) intended. The effect of not shifting can be obtained.
