Abstract

PURPOSE:To decrease the amount of load of the operator by transmitting a message such as introduction of a caller and a comment without direct talking to attain delicate correspondence in an exchange having a camp on function. CONSTITUTION:When an incoming call comes from a trunk line, it is received by a trunk line trunk COT, a controller CC is started and the operator of an attendant board ATT listens to the name of the caller and a comment such as business message and the number of an extension subscriber by talking with the caller. Then an extension subscriber EXT is called. When the extension subscriber EXT is busy, the operator requests the camp on connecting processing. The operator transmits the message such as the name of caller and comment listened to via a connected interface unit VCI to a voice storage device VM and stores therein. When the talking of the extension subscriber EXT completes talking, the message from the voice storage device VM is transmitted to the interface unit VCI and the talking is attained after the end.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention provides a method for transferring an incoming call from a central office line to an extension subscriber without the attendant's intervention. This relates to a voice camp-on method that conveys introductions and comments about the recipient of the call.

(Prior Art) Conventionally, in private branch exchanges, a waiting function, the so-called camp'-on method, has been used to reduce the workload of the relay operator (hereinafter referred to as the operator). . This means, for example, that an empty extension subscriber receives a call from another person (
For example, if there is an incoming call (for example, an incoming call from a central office line), the handler should keep the incoming call waiting, and connect the two parties directly at the same time the extension subscriber answers, or if the extension subscriber who is talking receives an incoming call from another person. In this case, the incoming call is kept waiting, and when the call ends, the extension subscriber is automatically called and the two parties are directly connected, or when the extension subscriber answers, the handler is called and the caller (e.g. There are connections made through operators who connect after listening to the introductions and comments of local line subscribers).

However, in the former case, the extension subscriber does not know who the caller is, and therefore, depending on how the caller responds, there is a risk that the caller may feel uncomfortable or inconvenienced. In this case, since the process goes through the handler, there is a risk of increasing the workload of the handler, which goes against the purpose of adopting the camp-on method.

(Purpose of the Invention) The present invention has been made in consideration of the above-mentioned concerns, and it notifies the extension subscriber of the caller's introduction and comments before connection with the caller, and It provides the necessary information to handle the connection, making it possible to pay close attention to the caller, and also aims to reduce the workload of the caller.

(Structure of the Invention) In other words, the present invention provides, in this type of switching device, a voice storage device that stores information about the caller such as an introduction and comments of the caller as a message, and an interface between the device and other switching devices. The system is equipped with a device to take the user's face, and is configured to send the stored message to the extension subscriber without the intervention of the operator before the connection between the extension subscriber and the calling party, This achieves the above objective. The present invention will be explained below using the drawings.

(Embodiment of the Invention) FIG. 1 is a relay system diagram showing an embodiment of the voice camp-on system according to the present invention, in which ExT' is an extension subscriber, LC is a line circuit, and NW is a communication path. , COT is central office trunk, POT is seat trunk, ATT is relay stand, TN
T is a signal tone trunk, CC is a control device which has a built-in memory and controls the entire seven stems, and these have the same functions as the constituent devices of a conventionally known switching device. Also, VM
and VCI are a voice storage device and a voice camp-on interface unit (hereinafter simply referred to as the interface unit) that constitute the main parts of the present invention, and the voice storage device VM is used to store information such as introductions and comments from central office line subscribers, which will be described later. The VCI is a device that stores voice messages as messages, and is an interface unit.VCI is a device that connects the voice storage device VM and other switching devices and provides an interface between the devices.

In the above configuration, when a call arrives from the central office line, the call is received by the central office line trunk COT, and the control device CC is activated. As a result, the control device CC connects the incoming call to the relay stand ATT via the seat trunk POT using route (3) according to a predetermined procedure. Through this connection, the operator of the relay stand ATT responds to the incoming call and speaks to the central office line subscriber (not shown) who is the calling party. Through this call, the operator listens to the number of the extension subscriber desired by the caller, the caller's name, and comments such as the purpose of the call. After this, the handler dials the number of the extension subscriber heard,
Call the corresponding subscriber.

Here, for example, if the extension subscriber EXT is busy, the operator uses a key etc. to operate the camp-on connection, that is, activates the control device CC via the seat trunk POT and requests the camp-on connection process. do.

Upon receiving this camp-on connection request, the control device CC stores the dialed extension subscriber's number in its built-in memory, and connects the office line trunk COT to the signal tone trunk TNT using route ■. Waiting sound etc. are sent to the interface unit MCI, and furthermore, control is executed to connect the relay stand ATT to the interface unit MCI using the route (3). Thereafter, the operator sends the name and comments of the heard caller as a message to the voice storage device VM via the connected interface unit (VCI), and sends the name and comment etc. Store in. Location information such as an address indicating the storage location of this message is exchanged between the interface unit VCI and the control device CC, and is stored in correspondence with the extension subscriber number stored in the built-in memory of the control device CC. . After this, the operator is freed from the series of operations and processes for the incoming call described above, and prepares for a new incoming call.

On the other hand, when the corresponding extension subscriber EXT ends the call and performs a response operation to the camp-on, for example, goes off-hook, the change in status is detected by the control device CC. That is, the control device CC constantly monitors changes in the status of all extension subscribers accommodated in the communication route hawk, and when it detects the change, it determines whether the extension subscriber is set for voice camp-on or not. It is determined whether or not it is possible by searching the built-in memory. 1Ulj control device CC connects the extension subscriber EXT to the interface unit MCI using route ■, since the extension subscriber EXT whose status has changed is set to voice camp-on. Transfer location information to the interface unit VCI. The interface unit VCI accesses the voice storage device (2) based on the received location information, reads out the message from the memory area, and sends it to the extension subscriber EXT using the set route (2).

Here, the interface unit (VCI) that received the location information determines in advance to inform the corresponding extension subscriber EXT that voice camp-on is set, before sending the message from the voice storage device VM. The identification information such as audible sound or voice is transmitted.

By receiving this information, the extension subscriber EXT can prepare for receiving subsequent messages.

When the transmission of the message is completed by the above control, the interface unit (VCI) sends termination information to the control unit You will be asked to connect to EXT. Upon receiving the request, the control device CC establishes a connection between the calling party on the central office line side and the extension subscriber EXT using route (3), thereby enabling a conversation between the two parties.

Here, when the response of the corresponding extension subscriber EXT is slow, for example, when the call continues and the preset time is exceeded, the control device CC monitoring the time is transferred to the relay stand AT.
Performs automatic call-back control to T and notifies the handler that the call is set to voice camp-on. This allows the handler to, for example, inform the caller and either continue waiting or
Alternatively, the user will be asked if he/she wishes to have the user call again, etc., and processing operations will be performed accordingly. In addition, the relay stand ATT
When there is an automatic call back to the caller, the content of the voice camp-on message stored in the voice storage device VM is determined by the operator who is aware of the caller's intentions, for example, the control device C.
It can be erased via C.

FIG. 2 is a relay system diagram showing another embodiment of the voice camp-on system according to the present invention, and the difference in the configuration here from that of FIG. 1 is that the voice storage device VM % interface unit VCI The devices constituting the system are the same as those shown in Figure 1 in that they are connected to the line circuit LC on the subscriber side, and their operations and processing are also the same as those shown in Figure 1. Therefore, the operation, processing, etc. will not be particularly explained here.

In the above description, the setting of voice camp-on was performed using the case where the extension subscriber is busy as an example, but the present invention is not limited to this. For example, if you receive a call from a central office line,
It is clear that the present invention can also be applied to a method in which a message is stored before calling an idle extension subscriber and a voice camp-on is then set up. In other words, regardless of whether the extension subscriber is free or busy, the operator can first memorize the message, then perform the camp-on connection operation and perform the control and processing described above. be. According to this control, it is now possible to perform operations that were previously performed by the operator, such as the waiting time until the subscriber responds on-hook when the extension subscriber is free, or in other words, to direct the subscriber to the extension subscription. Therefore, the time taken to process one incoming call reception can be shortened, and the number of reception processes handled by the handler per unit time can therefore be increased. This can be applied to workplaces with many incoming calls and can be expected to have great effects. During the process associated with the camp-on connection operation described above, if the extension subscriber is free, the control device immediately calls the subscriber and performs the same control and processing as described above. If the call is busy,
After the call is detected, the status of the extension subscriber is monitored, and the same control and processing as described above is performed along with the end of the call.

(Effects of the Invention) As described in detail above, according to the present invention, the operator can easily Since it is possible to introduce the caller and send messages such as comments without having to talk directly to the extension subscriber, the extension subscriber must know the other party (
This allows the user to know the caller (caller) and the content to be talked about,9 and thus to be able to respond in detail to the other party.

Furthermore, for the operator, there is no fear that the amount of work will increase even if the user connects to the camp-on, unlike the conventional technology, so the user can use the camp-on function even more than now, and therefore the amount of work for the operator is reduced. However, since it is possible to process incoming calls quickly, it is possible to reduce the number of handlers, or in other words, the number of relay devices.
It also has excellent cost advantages.
