Abstract

PURPOSE:To surely inform it to a caller that a telephone call is transferred to a transfer destination by informing information relating to the transfer destination in voice to the caller at absence transfer. CONSTITUTION:A standard pattern storage means 3 storing a prescribed standard pattern relating to a transfer destination and a voice output means reading the standard pattern of the transfer destination stored in the standard pattern storage means 3 at absence transfer, applying voice synthesis to the standard pattern and informing the result to the caller are provided. A voice output means 4 reads the standard pattern of the transfer destination stored in the standard pattern storage means 3 at absence transfer and applies voice synthesis to it and informs it to the caller, Thus, the fact of transfer to the transfer destination is informed to the caller by using a phone call.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a private branch exchange having a call forwarding function. [Prior art] In recent years, private branch exchanges have come into use that have a call forwarding function that automatically forwards incoming calls to the forwarding destination if you set a forwarding destination when you leave your seat. It has become. [Problem to be solved by the invention] However, in conventional private branch exchanges, when the call is automatically forwarded to the forwarding destination using the call forwarding function, the caller is not notified that the call is being forwarded. ．． For example, if the caller finds out that the number he/she dialed is different from the number he/she dialed when the caller connects with the forwarding destination, problems arise, such as the caller mistakenly thinking that he or she dialed the number incorrectly.

SUMMARY OF THE INVENTION An object of the present invention is to provide a private branch exchange that can reliably notify a caller that a call is being transferred to a transfer destination when a call is transferred.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a standard pattern storage means for storing a predetermined standard pattern regarding a forwarding destination in a private branch exchange having a call transfer function, and a standard pattern storage means for storing a predetermined standard pattern regarding a forwarding destination. The system is characterized by having an audio output means for reading out the standard pattern of the forwarding destination, audibly combining the standard pattern, and notifying the caller. The standard pattern is a voice standard pattern of the zero phone number of the transfer destination, or a voice standard pattern of a name corresponding to the transfer destination telephone number. [Operation] A predetermined standard pattern regarding the forwarding destination, for example, a voice standard pattern of the forwarding destination's telephone number or a voice standard pattern corresponding to the forwarding destination's telephone number is stored in advance in the semi-pattern storage means a. At the time of missed call forwarding, the voice output means reads out the standard pattern of the forwarding destination stored in the standard pattern storage means, synthesizes it into voice, outputs it, and notifies the caller. This allows the caller to be notified that the call is being forwarded to the forwarding destination. [Example] An example of the present invention will be described below based on the drawings. Referring to FIG. 1, the private branch exchange 10 of this embodiment includes an exchange section 1, a control section 2, a standard pattern storage section 3 that stores a predetermined standard pattern, and a standard pattern storage section 3 according to instructions from the control section 2. It is equipped with an audio output section 4 which reads standard patterns stored in the section 3, synthesizes speech, and outputs the synthesized speech. Terminal devices N1 to Nn are connected to this private branch exchange 10, and a predetermined telephone number is assigned to each terminal device N1 to Nn. Each terminal device N1-N
For example, the user of , sets the telephone number of the transfer destination terminal device in the control unit 2 of the private branch exchange 8110 by inputting a predetermined key (not shown) on his/her own terminal device when leaving his/her seat. , it is now possible to use call forwarding mode. For example, when the private branch exchange 10 receives a call from an external caller via the communication line 5, the exchange unit l calls one terminal device having the telephone number dialed by the caller. When the terminal device is in the absentee transfer mode, the control section 2 automatically calls a transfer destination terminal device having a telephone number preset in the control section 2 in response to an instruction from the control section 2.

In addition, the standard pattern storage unit 3 stores, as predetermined standard patterns, for example, voice standard patterns of numbers from "O" to "9", that is, voice standard patterns of telephone numbers of each terminal device N1 to No. Standard voice patterns of names corresponding to the telephone numbers of terminal devices N1 to Nn are stored in advance. Note that as a method of creating such a voice standard pattern, a voice input section and a feature extraction section are provided in the private branch exchange 10 (not shown), and when the private branch exchange 1110 is initialized, numbers or names are input aloud from the voice input section. Enter it with
When the feature amount of the input voice is extracted by the feature extraction unit, the extracted feature amount can be stored in advance as a standard voice pattern. At the same time, it instructs the exchange section 1 to call the destination terminal device, activates the voice output section 4, and outputs the voice standard pattern of the telephone number or name of the destination terminal device from the pattern storage section 3. This is read out and output as a voice prompt to notify the caller. Next, we will explain the operation of such an elliptical private branch exchange. Are the various terminal devices already stored in the standard pattern storage unit 3? If
It is assumed that voice tIA quasi-patterns of telephone numbers or names N1 to N are stored. For example, when the user of the terminal device N1 leaves his or her seat, the user manually selects a key from the terminal device N1 to a destination terminal device, such as N. Let us consider the case where the call forwarding mode is set by setting . At this time, if there is an @ call from the outside to this user's terminal device N1, the private branch exchange 1110 automatically forwards the call to the telephone number of the destination terminal device Nn. Along with this, the terminal device N of the transfer destination. The standard pattern storage unit 3 stores the standard voice pattern of the telephone number or name of
, the audio is synthesized by the audio output section 4, and the information to be forwarded to is notified to the external caller via the communication line 5. This allows the caller to reliably know that the call has been automatically forwarded to the forwarding destination notified by voice with the phone number or name, and prevents misunderstandings such as dialing errors. Can be done. In the above-mentioned embodiment, the call transfer was explained when there was an incoming call from an external caller. However, when there is an incoming call from an internal caller, for example, the terminal device N2, the telephone is transferred to the terminal in the same way. Transfer n to device N and terminal device N. It is possible to notify the caller of terminal device N2 that the transfer has been made. [Effects of the Invention] As explained above, according to the present invention, information regarding the forwarding destination is notified to the caller by voice when a call is forwarded. You can make sure that you know what is happening. In this case, if the forwarding destination phone number is notified by voice, the caller will know that they have been transferred to this phone number, and if the name of the forwarding destination is notified by voice, the caller will be able to know that the caller has been forwarded to this phone number. You can know that it has been forwarded first.
