Description

Automated answering device capable of confirming caller who did not leave a message and its control method

The present invention relates to a caller tracking device and method in an answering machine, and more particularly, to an apparatus and method for enabling a caller to disconnect even without leaving a message (voice) in the answering machine.

In general, the answering machine automatically generates a voice prompt message to the caller when the user is absent or difficult to answer the call, and receives and stores a message left by the caller, that is, his or her identity, an event or a phone number, so that the user can check it later. Play a role. However, the limitation of the conventional answering machine is that it is impossible to verify the identity of the sender who does not leave a message. In fact, after hearing a voice prompt, many people are silent for a long time and then hang up without leaving a message. Therefore, no identity can be identified for these callers.

Accordingly, an object of the present invention is to provide an apparatus and method for enabling a caller to disconnect even without leaving a message (voice) on the answering machine.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. Also, in the following description, many specific details such as components of specific circuits are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It is self-evident to those of ordinary knowledge in Esau. 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.

1 is a block diagram of an automatic answering device capable of confirming a caller who does not leave a message according to an embodiment of the present invention and a peripheral device thereof. Reference numerals 100 and 200 denote a called party telephone and a calling party telephone, respectively, and an answering machine 200 is connected to the called subscriber telephone 100. Reference numeral 300 is a switch, and has a subscriber-specific database 340 for storing a talk time as shown in the figure, and when the caller trace request signal is received from an external answering machine, based on the data registered in the database 340. Tracking device 320 for transmitting tracking data to the answering machine.

2 is a detailed configuration diagram of the answering machine of FIG. 1.

The controller 210 collectively controls the overall operation of the answering machine, and is a one chip microprocessor having a ROM and a RAM. The ROM is masked with a control program and related data for controlling the operation of the answering machine and the caller identification process as shown in FIG. In addition, the control unit 210 has a predetermined timer 216, the timer 216 is driven when it detects the formation of the call between the answering machine and the caller, from which time the non-voice state continues until the call is released. Check the time remaining. Line interface unit (LIU) 220 realizes the interface between telephone line (T, R: tip, ring) and answering machine through signal matching. The ring detector 220 detects a ring signal transmitted through a telephone line and notifies the controller 210 of an incoming call. The dual tone multi frequency (DTMF) detector 250 decodes the DTMF signal received through the LIU 280 and provides digital tone information to the controller 250. In this embodiment, the tracking data received from the exchange 300 takes the form of the digital tone information. The guide voice message generator 260 digitizes various types of guide voices input by the subscriber with the answering machine, such as an absence of absence or other special contents, and stores them in a storage medium such as EEPROM. Under the control of the controller 210, one of these is read out from the storage medium to synthesize a voice, and a guide voice message is sent to the telephone line through the LIU 260 to automatically guide the caller. The memory 270 stores the tracking data received from the exchange 300, that is, the sender information, and may use EPI. The voice synthesizer 280 synthesizes caller information read from the memory 270 into an analog voice under the control of the controller 210 and transmits the synthesized caller information to the speaker 240. The caller information is a caller's telephone number, a call date and time (date, time), and the like. The display unit 290 visually displays caller information read from the memory 270 under the control of the controller 210. The key input unit 300 is a user interface unit and has a key for making a request for confirming information about a caller who has not left a message.

3 is a flowchart illustrating a process of executing tracking and confirmation for a caller who does not leave a message in an automatic answering device according to an embodiment of the present invention.

When a call path is connected between the caller and the called phone, the control unit recognizing the call transmits the missed voice guidance message in step 3a. In operation 3b, the operation of the first timer is started. In step 3c, it is checked whether there is a message received from the sender. At this point, if there is a message received from the sender, the operation ends. On the other hand, if there is no message received from the sender, it checks whether it is hooked on in step 3d. If the check result is not detected, the process returns to step 3c to check whether there is a message received from the sender, and if there is no received message, the process proceeds to step 3d to check whether the message is turned on or not. Keep repeating until it is detected or there is an incoming message. In the absence of a received message, the controller proceeds to step 3e and checks the first timer to determine whether the non-voice state is maintained longer than a predetermined reference time. If the non-speech state maintenance time is longer than the reference time, the tracking request signal is transmitted to the electronic exchange in step 3f. Thereafter, in step 3g, a response to the tracking request signal is received from the electronic exchange, that is, caller information. If caller information is received, the caller information is registered in the memory in step 3h.

Thereafter, in step 3i, when a request for checking information about a caller who has not left a message is detected through the key input unit 300, the stored caller information is read by accessing the memory 270 in step 3j. In step 3k, the read caller information is transferred to the voice synthesis unit 280 or the display unit 290. In this way, caller information is generated as a voice message by voice synthesis or displayed on the display unit 290 in the form of text.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made 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.

As described above, the present invention can check the caller who has not left a message (voice) in the answering machine, so that the user can appropriately cope with an important call and solve the question.
