Description

Caller Information Processing Method Using Automatic Guidance Function in Private Exchange

The present invention relates to an auto attendant function of a private exchange, and more particularly, to a method of receiving and processing caller information when an incoming subscriber is absent or busy.

The auto attendant function refers to a function of automatically answering an incoming call and diverting a call to an incoming subscriber selected by the caller. At this time, if there is no response from the called party, the call is transferred from the originator to another selected called party or the call to a specific subscriber group.

As described above, in the conventional automatic guide function, the function of switching the incoming call is mainly used, and thus, when the call is not made according to the incoming call, the called party could not know the information about the incoming call at all. As a result, caller information could not be managed, making it difficult to respond to an incoming call.

Accordingly, an object of the present invention is to provide a method for notifying a called party by separately managing caller information when a call is not made according to the CO line.

In order to achieve the above object, the present invention, if the call with the incoming subscriber according to the incoming call is not connected in the state that the automatic guidance function is set up, after receiving and storing the caller information from the calling party, It provides the stored caller information.

First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings.

1 is a view showing the configuration of a private exchange according to an embodiment of the present invention.

Referring to FIG. 1, the controller 10 controls the overall operation of the private exchange according to the program set in the ROM 12. The ROM 12 stores an initial program and an operation program of the controller 10. The RAM 14 stores the extension number for performing the exchange function and the data generated according to the performance of the function. In addition, it has a subscriber-specific caller information table for receiving and managing the caller information generated by the implementation of the present invention. The switching circuit 16 performs a switching operation under the control of the control unit 10 to form a loop for making calls between stations and between stations. The trunk line circuit 18 connects a plurality of trunk lines drawn from a local exchanger (not shown) under the control of the controller 10 to the switching circuit 16. In addition, the trunk line circuit 18 detects a ring received through the trunk line and provides the ring to the controller 10. The extension circuit is largely divided into the subscriber subscriber circuit 20 to which the general subscriber is connected and the key subscriber subscriber circuit 22 to which the key subscriber is connected. The extension subscriber circuit 20 performs a function of monitoring the state of a plurality of extension subscribers (general telephones) and supplying a call current during a call. In addition, a plurality of general telephones are connected to the switching circuit 16 under the control of the controller 10. The key phone dedicated subscriber circuit 22 performs functions such as monitoring the state of a plurality of extension key phone subscribers (key phone phones) and supplying a call current during a call. In addition, the key phone, the voice line and the data line is connected, and under the control of the control unit 10 to connect a plurality of key phone telephone to the switching circuit (16). The ring generator 24 receives the control of the controller 110 in response to a call request to a specific extension subscriber authorized through the trunk line circuit 18, the extension subscriber circuit 20, and the key subscriber circuit 22. Send out the ring. The DTMF receiver 26 converts the DTMF received through the trunk line circuit 18, the subscriber line circuit 20, and the key subscriber circuit 22 into specific data, and provides it to the controller 10. The DTMF generator 26 generates DTMF under the control of the controller 10. The automatic guide device 30 switches the ring received through the trunk line to the corresponding subscriber by setting the automatic guide mode. In addition, the automatic guide device 30 has a function of reproducing and transmitting a voice guidance message required for incoming ring switching.

2 is a diagram illustrating a control flowchart for processing caller information according to an embodiment of the present invention.

2 is a process of switching the incoming call to the called party selected by the calling party when the incoming call is detected through the CO line when the automatic guide function is set, and requesting input of caller information if the incoming subscriber does not respond. Transmitting a message; storing caller information when the caller information is input in response to the guide message; and transmitting the stored caller information in response to a request of the called party.

Hereinafter, preferred embodiments of the present invention will be described in detail.

The controller 210 performs the automatic guide mode according to the user's request in step 210. Substantial operation according to the automatic guide mode is performed in the automatic guide device 30, the control unit 10 is a switching circuit 16 for switching the incoming ring through the trunk line circuit 18 to the automatic guide device (30) ).

When the automatic guide mode is set, the controller 10 detects a ring that is received through the trunk line circuit 18 in step 212. The trunk line circuit 18 typically includes a circuit for detecting an incoming ring, and provides a detection signal to the controller 10 when the incoming ring is detected. When the CO line incoming ring is detected, the controller 10 controls the switching circuit 16 to connect the CO line received by the ring to the automatic guide device 30, and then proceeds to step 214. The controller 10 proceeds to step 214 to control the automatic guide device 30 to send a response message requesting the selection of the incoming subscriber to call. Typically, the automatic guide device 30 has a voice guidance function. The sent response message is transmitted to the calling party through the switching circuit 16 and the trunk line circuit 18. For example, press the extension number you want to call. If you do not know the extension number, press 0. You can use the voice message.

The control unit 10 detects the input of the extension number of the called subscriber who responds to the response message in step 216 after transmitting the response message. The extension number means a unique number of the extension subscriber connected to the subscriber subscriber circuit 20 or the key subscriber subscriber circuit 22. The input extension number is a typical DTMF, and the input DTMF is detected through the DTMF receiver 26. If the controller 10 detects the extension number through the DTMF receiver 26, the controller 10 proceeds to step 218 and calls the called subscriber corresponding to the detected extension number. The call of the called party is made by providing the ring subscriber with the ringing sound generated by the control of the ring generator 24.

The controller 10 detects the answer of the called subscriber in step 220 after calling the called subscriber. The incoming subscriber's response is detected through a hook-off detection unit provided in the subscriber subscriber circuit 20 and the key subscriber subscriber circuit 22. When the response is detected, the controller 10 proceeds to step 222 to control the switching circuit 16 to switch the ring to the corresponding subscriber.

However, if the response is not detected, the flow proceeds to step 224 to control the automatic guide device 30 to send a guide message. The announcement message is a voice announcement message requesting the selection of another called party or input of caller information. For example, if you are on a call, enter a different extension number or enter your charge number. After transmitting the announcement message, the control unit 10 proceeds to step 226 and detects the DTMF received from the calling party in response to the announcement message, and determines whether it is a DTMF corresponding to another called subscriber or a DTMF corresponding to caller information. do. If it is determined in step 226 as a DTMF to select another incoming subscriber, the control unit 10 returns to step 214 to repeat the process of switching the incoming ring. However, if it is determined in step 226 as the DTMF corresponding to the caller information, the controller 10 proceeds to step 228 and stores the received caller information in the subscriber-specific caller information table of the RAM 14. The caller information is information for distinguishing a caller's telephone number and a caller, and when the caller information is stored, the caller's time is detected together with the incoming call time detected in step 212. The caller information table is managed separately for each subscriber including the key subscriber.

An example of a caller information table that stores and manages caller information and incoming call time of a specific extension is shown in Table 1 below.

TABLE 1

Caller Information Incoming time 460-1234 12:00 460-6666 03:20 123-4567 05:45

Table 1 shows that the call came from 460-1234 at 12 o'clock, 460-6666 at 3:20, and 123-4567 at 5:45.

When the storing of the caller information is completed, the controller 10 determines whether the incoming subscriber is a key subscriber or a general subscriber. The key subscriber and the first subscriber's judgment may be determined by searching the extension number stored in the RAM 14. The general subscriber and the key phone subscriber are not shown in FIG. 1, and refer to a general telephone and a key phone telephone. If it is determined in step 230 that the subscriber is a general subscriber, the function according to the present invention is terminated. In step 232, the controller 10 transmits a call message to the called subscriber. The call message is a message for notifying that an incoming call has been received, and a key phone telephone corresponding to the key phone subscriber indicates that an incoming call has been made by lighting an LED of a specific key when the call message is received.

In addition, when the automatic guide mode is set in step 210, the controller 10 detects input of key data corresponding to the confirmation key from the extension key phone subscriber through the key phone dedicated subscriber circuit 22 in step 234. The confirmation key is used as a key for requesting confirmation of the caller information received as a key provided in the key phone for the purpose of carrying out the present invention. The confirmation key may be used in the same manner as the key that is turned on by the call message transmitted in step 232.

In step 234, if the input of the confirmation key is detected, the control unit 10 proceeds to step 236 and transmits the caller information and the incoming time of the caller information table for each subscriber illustrated in Table 1 to the key phone subscriber who inputs the confirmation key. do. The transmitted caller information and incoming call time are displayed on the display window of the key phone telephone corresponding to the key phone subscriber and stored in the dial buffer for memory dialing.

On the other hand, the call message transmitted to the key subscriber in step 232 and the caller information and the incoming time transmitted to the key subscriber in step 236 is transmitted through the data line, not the voice line.

In the present invention, if the call is not made according to the incoming call, the caller information is received and stored and the caller information is provided to the called party so that the information on the incoming call can be known. As a result, caller information can be managed, so that there is an effect of quickly and accurately responding to an unanswered call.
