Abstract

PURPOSE:To enable a designated extension subscriber to respond to a perfectly retention call by broadcasting voice information representing transfer destination from an extension subscriber through a speaker in a decentralized attendant board system. CONSTITUTION:Suppose that an extension subscriber 1 reserves a trunk line trunk 3 by a predetermined perfect retention operation during talking through the trunk 3. Then the subscriber 1 makes registration to a storage device 6 in voice so as to be responded to the reserved trunk 3 to an extension subscriber 2. When the subscriber 1 hooks on, a central processing unit 8 detects it, restores a channel 1 so as to connect the storage device 6, a loop trunk 4 and a speaker 5. Thus, the stored voice is reproduced from the storage device 6 and broadcast through the speaker 5. When the called subscriber 2 responds to it by dialing a specific number, the subscriber 2 is connected to the trunk 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a simple transfer system for an electronic private branch exchange device using a distributed repeater system.

[Prior art]

Conventional 1 In this type of simple transfer operation, the handler who answered the incoming call on the central office line performs a complete hold operation and verbally informs the handler of the transfer destination of the central office line number, etc.). However, this method has the disadvantage that the handlers must be within a distance where they can communicate verbally with each other, especially if the distance is If the user is far away, there is no way to contact the destination, and if paging is used, there is no other way to contact the destination when the paging device is busy.

〔the purpose〕

The present invention connects the extension subscriber who performed the complete hold operation to the voice storage device, and the name of the extension subscriber to whom the simple transfer is transferred,
Alternatively, by storing the extension number as audio information and broadcasting the stored audio through a speaker, incoming calls from an extension subscriber who has performed a complete hold operation can be transferred to the destination extension subscriber. The purpose is to provide a simple transfer method.

[Structure of the invention]

In order to achieve the above object, the uninvented invention provides an electronic private branch exchange system using a single distributed relay system, including a voice storage device,
Connect the speaker and the extension telephone of the extension subscriber who performed the complete hold operation to the voice storage device, and retrieve the voice information indicating the transfer destination of the simple transfer stored in the voice storage device by the extension subscriber. , and a central processing unit that broadcasts through a speaker, and the extension subscriber designated by the broadcast responds to a completely held call.

〔Example〕

Next, embodiments of the present invention will be described using the drawings.

FIG. 1 is a schematic block diagram of a distributed relay stand type electronic private branch exchange device according to an embodiment of the present invention.
2 is an extension subscriber's telephone, 8 is a central office line trunk, 8a is a central office line, 4 is a loop trunk 15 is a speaker, 6 is a voice storage device, 7 is a communication path switch, 8 is a central processing unit, and 9 is a main storage unit. , and 10 is a pass line. The central processing unit f8 connects the extension telephones 1 and 2 to the voice storage device 6 via the switch 7 in response to a complete hold operation from the extension telephones 1 and 2, and furthermore, the central processing unit 8 connects the extension telephones 1 and 2 to the voice storage device 6 via the on-hook signal from the telephones. , the function of connecting the audio storage device 6 and the loop trunk 4, and the loop trunk 4 and the speaker 6 via the switch 7.

The operation of the above configuration is controlled by the subscriber of extension telephone 1! 1li
A case will be described in which the call is transferred to the subscriber of the 1-extension telephone 2 via the i8a and the central office trunk 8 during a call.

The subscriber of extension telephone 1 performs a complete hold operation determined by the system (for example, a hooking operation and a special number dialing for complete hold) during a call through the central office line 8a and central office line trunk 8 (call path marked ■ in the figure). central office trunk 8
will be put on hold. Next, the central processing unit 8 identifies that the complete hold operation has been performed, and connects the extension telephone ml and the voice storage device 6 via the switch 7 (■ in the figure). Therefore, the subscriber of the extension telephone 411 registers in the storage device 6 through the telephone 1 a voice requesting the subscriber of the extension telephone 2 to respond to the central office trunk 8 held on hold. After this registration is completed, when the subscriber of extension telephone 1 goes on-hook, 1 central processing unit 8
detects this on-hook signal, restores the communication path (■) between extension telephone 1 and office line trunk 8, and connects voice storage device M6 and loop trunk 4, and speaker 5 and loop trunk 4.
Connect as shown in ■ in the figure. The voice stored from the voice storage device 6 is played back and broadcast through the speaker 5, and the called subscriber on the extension telephone 2 dials a special number for answering to call the central office trunk 8 that is on hold. Connected (■ in the diagram).

Furthermore, if the interval and number of broadcasts by the speaker 5 and the number of the transferee's telephone, that is, the extension telephone 1, are stored in the main storage device 9, if the subscriber of the transferee's extension telephone is absent, By reconnecting the transferer and the office line trunk 8, the incoming office line call can be returned to the transferer.

〔effect〕

As explained above, according to the present invention, simple transfer, which conventionally could only be performed within the range of verbal communication using a complete hold operation, is now possible even within the -i/1 range of the voice. .
