And a control unit which controls to generate and store the voice message data in the voice data storage.

According to the present invention having the above-described configuration, when a call comes from a telephone number set by the user, a special telephone ring sounds, and after the other voice data is already stored for the received voice data, even if the memory capacity exceeds the previous voice data Clears the audio data received from the set phone number first.

Therefore, even if the user is absent, it is possible to prevent the loss of important voice message contents from the contracted telephone number.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 2 is a block diagram showing an internal configuration of a phone having a user-set priority memo function according to an embodiment of the present invention. In FIG. 2, the same components as in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted. do.

In Fig. 2, reference numeral 21 denotes a key input unit provided with a setting key 21a and a 10-key 21b for setting a specific telephone number, and 22 denotes a key input unit for storing a telephone number set through the key input unit 21. The setting data storing unit 23 is a telephone number detecting unit for detecting telephone number data among signals received by the trunk line.

In addition, reference numeral 24 is a special ring signal generation unit for generating a special telephone ring sound in accordance with a predetermined control signal, 25 is the set data storage unit 22 of the incoming signal from the trunk line through the telephone number detection unit 23 When the set phone number data is detected, the special ring signal generation unit 24 generates a special ring signal, and then controls to store the received voice message data in the voice data storage unit 15 first. The microprocessor is a microprocessor, and 26 is a mode state storage unit for storing a mode state set through the key input unit 21.

Next, the operation of the device having the above configuration will be described with reference to the operation flowchart shown in FIG. 3.

First, a user sets a specific telephone number through the key input unit 21. When the user inputs the setting key 21a (step ST1), the microprocessor 25 sets the mode to the mode state storage unit 26. (Step ST2).

Subsequently, when a telephone number is input by the user through the 10-key 21b of the key input unit 21 (step ST3), the microprocessor 25 sends the input telephone number to the setting data storage unit 22. It is stored as data (ST4 step).

Therefore, the setting of the specific telephone number is completed by the above process.

Thereafter, when an incoming call is received from the CO line in the state where the telephone number is set as described above (ST11 step), the telephone number is detected from the telephone number detector 23 (ST12 step), and the detected telephone number is stored in the setting data. If it does not match the telephone number stored and stored in the unit 22, the microprocessor 25 outputs a general ring signal through the ring generating unit 3 (step ST13).

However, when the telephone number data detected from the telephone number detector 23 matches the set telephone number, the microprocessor 25 outputs the special ring signal through the special ring signal generator 24 (step ST14). ).

After the ring signal is output for a predetermined time, if a hook switch (not shown) is turned on due to a user picking up the handset 5 to receive a call, the off-hook is detected through the hook detection unit 8. (ST15 step), the microprocessor 25 turns on the call path connecting portion 6 and performs normal control processing related to the call (ST16 step).

When the on-hook is detected through the hook detection unit 8 (step ST17), the microprocessor 25 turns off the communication line connection unit 6 and terminates.

On the other hand, if the off-hook is not detected through the hook detector 8 even after a predetermined time elapses after outputting the ring signal in step ST5 (step ST18), the microprocessor 25 controls the DSP 17 to control the DSP 17. The voice message related to the automatic response is read from the guide message storage 9, and converted into an analog signal through the codec 16 to be output to the trunk line (ST19).

Thereafter, the microprocessor 25 receives the voice message from the other party's telephone after transmitting the guide message. Then, the received voice data is demodulated into a digital signal through the codec 16 and stored in the voice data storage 15.

However, the microprocessor 25 checks whether the memory capacity is sufficient before storing the voice data in the voice data storage unit 15 (step ST20). After the voice data previously stored in the data storage unit 15 are cleared, the received voice data is stored (step ST21).

However, if it is determined that the memory capacity of the voice data storage unit 15 is sufficient, the microprocessor 25 immediately stores the received voice data in the voice data storage unit 15 (step ST22).

When the voice data is received and stored for a predetermined time and the function is completed (step ST23), the microprocessor 25 ends by controlling the communication line connection 6 off (step ST24). ).

Thereafter, the user presses a function key (not shown) related to the output of the received voice message provided in the key input unit 21 to confirm whether the voice message is received. ) To read out the received voice message stored in the voice data storage unit 15, convert it into an analog signal through the codec 16, and output it as an audible sound through the handset 5 or a speaker not shown. Done.

That is, according to the above embodiment, when a call comes from a telephone number set by the user, a ring tone of a special tone is generated, and when an automatic answer is executed, a telephone that first stores the received voice data can be realized. do.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, when a call comes from a set phone number even when the user is absent, the received voice data is stored first, thereby realizing a phone that can prevent the loss of voice messages of important contents. .
