The present invention relates to a call processing method of an answering machine, and more particularly, to a method for answering a missed call and a call transfer method.

In the case of using an answering machine, the user records the purpose of going out, where to go out or when to return, and sets the outing mode. If you do this, most outgoing messages (response messages) will end up asking the caller to call again or to record the call. Therefore, the caller is frequently embarrassed by a sudden response message or is offended and hangs up the phone without recording the case. In addition, there was an inconvenience of having to wait for the person who checked the recorded message to call (call) again, even when an emergency call occurred. This will be described in detail as follows.

1 is a configuration diagram of an answering machine, and the line interface and the call line 10 are circuits for modifying a signal from an extension of a simple switch (car or private exchange) to suit characteristics, and are connected to a general telephone line or a switch dedicated telephone. Can be divided into: The ring signal / data detector 20 detects a ring. The central processing unit 110 is composed of a ROM storing a program necessary for an automatic response and a relay, a RAM storing a state necessary for the operation, and various interrupt clock functions. Overall control of overall operations such as counting. The switching unit 30 is for connecting or shorting each circuit under the control of the central processing unit 110. The voice input unit 40 is a circuit for converting a voice signal electrically, and is comprised of a handset, a microphone, or the like of a handset. The voice output unit 50 is a circuit for converting an electrical signal back into a voice signal and includes a handset or a speaker of a handset. The key input unit 600 is used as a button for performing various functions, and the display unit 700 is required to show the setting state of the function, but is not an essential component and may use other display methods. The D / A, A / D converter 80 is a circuit that stores an analog audio signal coming through the switching unit 30 and converts the stored data back into an analog signal, commonly referred to as a codec. However, if audio is not recorded as digital data, this codec is not necessary. The voice signal processor 90 is for storing and reading digital signals, and includes a digital signal processor and a subprocessor. Even in this case, when the analog signal is stored in a cassette or the like, it is replaced by a circuit for processing the analog signal. The voice storage unit 100 generally refers to a DRAM when storing a digital signal and a cassette tape when an analog signal is used. On the other hand, a fixed guide message or the like is stored in a ROM.

2 is a flowchart illustrating an operation of processing a call received by any one subscriber in the above-described answering machine when the subscriber is absent. Step (2a) is a step of detecting a ring signal and counting the number thereof. At this time, the input ring signal is an analog signal when the device can be connected to a general telephone line. However, in the case of the key answering machine, the ring data is received by exchanging data with the main device. The ring signal introduced in this manner is sent to the central processing unit 110, and the central processing unit 110 counts it and performs step (2b) when the number is already set. In step (2b), in response to the desired number of ring signals input, the central processing unit 110 controls the line interface and the call path 100 so as to be connected to the other party, and then the response message data stored in the voice storage unit 100. Read out. The read data is processed through the voice signal processing unit 90, and then converted into analog voice signals by the D / A and A / D converters 80, and then the switching unit 30 and the line interface and the communication path 10 are exchanged. It is sent out to the other party. After that, in step (2c), it is checked whether message transmission is completed. In step (2d), it is determined whether a mode of recording a received message or a mode of not recording. If you are in the incoming message mode, go to step (2e) to record the message so that the caller can leave a message. When recording ends in step (2f) and the caller hangs up, the caller recovers the call and hangs up and waits for the next call.

In this way, the caller simply sends a response message to inform the caller of his absence and call back or record the call. However, in the case of using an answering machine in an office or a public institution other than a home, most of them have a colleague or secretary who works with the extension of the seat next to each other. To this end, no such method has been developed to date.

Accordingly, an object of the present invention is to provide a method for allowing a caller to directly request a call transfer to another extension while listening to an automatic response message or leaving a voice memo.

In order to achieve the above object, the present invention is connected to a simple exchange, and in a method for processing a missed call of a subscriber in an answering machine capable of recording and sending a voice message, in response to detecting a predetermined number of ring signals. A first process of connecting a call path and transmitting a voice guidance message; and recording a received message from a calling party for a predetermined time after sending the voice guidance message, and a call transfer code from the calling subscriber is recorded while the recording is being made. And a second process of checking whether the call is input or not, and when the input of the call transfer code is confirmed in the second process, recording is stopped and the call exchange extension information predetermined by the simple exchange is transmitted to the simple exchange. Characterized in that the third process to switch the call to the subscriber corresponding to the extension number do.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following description, numerous specific details such as components of specific circuits are shown, which are provided to help a more general understanding of the present invention, and it is understood that the present invention may be practiced without these specific details. It will be self-evident to those of ordinary knowledge. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The configuration of the answering machine to which the present invention is applied is the same as that of FIG.

3 is a flowchart illustrating a response to a missed incoming call and a call switching process according to an exemplary embodiment of the present invention. Steps 3a to 3d are the same as those of FIG. In step (3e), when it is found that the reception message recording mode is set in step (2d), the central processing unit 110 operates the voice signal processing unit 90 to start recording the reception message. In step (3f), it is determined whether the recording of the received message is finished.

According to the present embodiment, the call transfer code is input from the outside during the response message transmission or the recording of the received message. If the call transfer code is input, the recording is stopped and the corresponding extension number (for example, the telephone number of the next digit) Can be switched to). In the former case, even when the recording of the received message is not finished, the input of the call transfer code is detected in step (3g). In this case, the process proceeds to step (3h) to stop recording, and transfers the call transfer extension number specified in advance to the simple switch in step (3i). In this case, the simple exchange transfers the call to the subscriber corresponding to the extension number. After performing step (3i), the process proceeds to step (3k) to release the call path to answer the next call. The latter case is a case where the call transfer code input from the outside is detected in step (3j) before the response message transmission completion state is detected in step (3c). At this time, also proceeds to step (3i) and transfers the predetermined call transfer extension number information to the simple exchange. In this case, the simple exchange transfers the call to the subscriber corresponding to the extension number. After performing step (3i), the process proceeds to step (3k) to release the call path to answer the next call.

In addition, when recording of the received message is normally completed in step (3f), the process proceeds to step (3k) to release the call.

On the other hand, the call transfer code uses one digit and has a memory for the actual extension corresponding to the one digit. The following is an example of a response message.

Hello? ○○○ I am absent now, so please speak after hearing the beep. If you are in a hurry, please press the eye (*) on the phone and it will be connected to △△△. Thank you.

In other words, before going out, select the outing mode, record the response message as described above, and register the extension number of the person to whom the call is transferred, that is, the adjacent person who can answer the call, in the memory. In this case, when the caller hears the message and presses a call transfer code (eg, an eye mark), the call is automatically switched to the extension number of the neighboring person.

As described above, the present invention converts a call so that a call can be made directly with another person when the other party is absent, so it is easy when an important contact is immediately communicated to someone when the party is absent. When used in conjunction with an extension, the effect can be further increased.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.
