JP4876811B2 - Telephone device with answering machine with specific partner priority playback function - Google Patents

Description

  The present invention relates to a key telephone system that accommodates a plurality of extension telephones or an answering voice recording function of a PBX (private branch exchange).

  Home telephones with an absence recording function as a basic function have become widespread, but in recent years, an absence recording function has become common in telephone systems such as a button telephone system and PBX introduced in the company. . In addition, many companies use the caller ID notification function, and the caller ID notification function and the absence recording function are combined to display the other party's phone number and name when playing recorded messages. In addition, there has been proposed one that enables visual confirmation of whether or not recording is from a desired partner even before each message is reproduced.

  However, in the method of displaying the other party's phone number or name on the display of the telephone at the time of playback operation, it is necessary to skip other message messages until the message message from the desired party is reached, and the desired message is immediately It was difficult to play back a business message from the other party.

  In view of this, there is disclosed a technique for preferentially reproducing the message, which is displayed on a telephone display or the like when a message is recorded from a caller that matches a pre-registered telephone number (for example, Patent Document 1).

JP-A-11-8691

  Although the technology disclosed in Patent Document 1 is effective for a single telephone used at home or by an individual, a telephone system used in a company has a plurality of extension telephones that share a plurality of external lines, and also has an absence recording function. Since it is common to have an absence recording function that is used in common with the main unit rather than for each telephone, all caller's requirements are recorded using the common absence recording function and managed collectively. However, there is a problem that each person in charge wants to play the message with priority.

  In addition, when used in a company, a target person who wants to reproduce a message preferentially has a larger number of telephone numbers to be registered than personal use. It takes time and effort to register the memory, and there is a problem that memory is wasted.

  Also, if the telephone system used in the company has an absence recording function that is used in common with the system, all caller's requirements are recorded and managed collectively using the common absence recording function. There is a problem that even a message that is not desired to be heard by the person in charge can be reproduced from any extension telephone.

  In addition, when the telephone system used in the company has an absence recording function that is used in common with the system, all caller's requirements are recorded and managed collectively using the common absence recording function. There is a problem that it is a message that the person in charge needs to listen to and can be deleted from other extension telephones even if the person in charge has not yet played back.

  The object of the present invention is to solve these problems of the prior art.

In order to solve the above-mentioned problems, the first invention is that the key telephone main device uses a message recording information storage means for storing caller information and a message number when recording a message, and the button telephone is used. Specified person information storage means for each of the key telephones for storing the information of the other party to be preferentially reproduced at the time of message message reproduction together with the priority rank, sender information stored in the message recording information storage means and the specific person information storage means The priority processing message number storage for storing the message number for priority playback for each key telephone if the verification result of the verification processing means matches the verification processing means for verifying the information of the other party stored in and means, in accordance with whether business message number is stored in the priority reproduction message number storage unit, the priority re-performs display on the key telephone set And message existence display means, by preferentially reproduction operation of the key telephone, priority to play business message corresponding to the message number stored in the preferential reproduction message number storage unit in the priority rank order of the priority reproduction message number storage means Reproduction regulation that enables reproduction control means and a message from a specific person stored in the specific person information storage means to be reproduced only from a key telephone stored in the specific person information storage means. And an erasure restricting means for invalidating the erasure operation when one or a plurality of key telephones to be preferentially reproduced is not reproduced with respect to the message having the message number stored in the preferential reproduction message number storage means. It is characterized by having.

  In addition, according to a second invention, in the first invention, the specific person information storage means can store a group number of the telephone book of the self-button telephone system in addition to the telephone number as a condition for limiting the specific person. It is characterized by that.

According to the present invention, even with the absence recording function common to the system, it is possible to register the party to whom the message message is preferentially reproduced for each extension telephone, and priority reproduction of the message message independent for each extension telephone. Can be used.
In addition, even if the message recording function is common to the system, if a message for a message from the other party registered by each extension telephone is recorded by registering the party to whom the message is preferentially played for each extension telephone, Visible display and audible display can be performed only on the corresponding telephone.
In addition, even if the messages of all callers are recorded and managed in a batch using the common absence recording function, the message messages from other parties who do not want to be heard by other people can only be played back by themselves. .
In addition, since the message of the other party registered for priority playback cannot be deleted unless all the persons in charge play it back, it is possible to prevent the person in charge who wants to play back the priority message from being overlooked. it can.

According to the second invention, it is generally possible to set a group of important customers, company executives, employee mobiles, etc. when registering a phone number in the system common phone book. Priority play is also considered, group registration of the phone book is performed, and when registering the party to be played back with priority, registering the phone book group instead of the phone number simplifies the task of registering the party to be played back with priority play. It is also possible to save the memory usage area.

  Hereinafter, embodiments of the present invention will be described. In the following embodiments, a button telephone main device and a wired extension telephone connected to the button telephone main device will be described as examples of the button telephone device. However, the present invention is not limited to this. For example, a wireless extension telephone can be used instead of a wired extension telephone, and it may be implemented by a private branch exchange instead of a button telephone apparatus. Further, the outside line may be any line that can acquire the telephone number (also called calling number) of the caller, and any of an analog line, ISDN line, and IP line can be used. When the outside line is an IP line, the source IP address may correspond to the calling number depending on the network.

I can't. However, the telephone in which the specific person is registered in the specific person list can be played back. In the example of FIG. 4, the telephone number “03123342222” is restricted in the telephone of the accommodation position 101, but Since the telephone number “03123342222” is also registered as the telephone specific person, when the normal reproduction is performed, in addition to the telephone at the accommodating position 101, the telephone at the accommodating position 120 also reproduces the message of the telephone number “03123342222”. It is possible.

  Next, a configuration example of the priority playback message number list in the priority playback message number storage means F56 will be described with reference to FIG. The priority playback message number list is managed for each key telephone connected to the extension, and is arranged in order of recording date and time. In this embodiment, the priority rank for determining the rank of the opponent to be preferentially reproduced is shown, and the reproduction is performed in the order of priority rank 1, priority rank 2,. The priority rank is specified in advance by the specific person list (FIG. 4), and when the message number is registered in the priority reproduction message number list, the priority rank of the specific person list (FIG. 4) is also registered.

  Next, the recording process flow on the key telephone main device 10 side in the above embodiment will be described with reference to FIG. In addition, in FIG. 6, the order of each step shows an example, and may be arbitrarily changed within a range in which the operation / effect is not changed.

  First, after receiving an outside line, a calling number reception process is performed (S201). Since the calling number reception process is known, the details are omitted.

  After performing the answering machine response, the recording process and the recording end process are performed (S202). Since the answering machine response, the recording process, and the recording end process are well known, the details are omitted.

  When the recording is completed, the message number, the recording date and time, and the calling number are registered in the recording information list (FIG. 3) by the message recording information registration means F46 (S203).

  Immediately after step S203, the call processing number F is checked by the matching processing means F50 to see if it matches the other party in the specific person list (FIG. 4) of each telephone (S204). If they match, it is checked whether the matched specific person partner is registered in the specific person list (FIG. 4) as a target for normal playback (S205). A partner to which “S” is assigned in the priority rank column in the specific person list (FIG. 4) corresponds to the normal reproduction restriction target.

  If the message number is subject to restriction in step S205 (Yes), the message number is restricted to the corresponding message number in the recording information list (FIG. 3) in order to restrict reproduction when normal reproduction is performed from another telephone. A symbol (“S” in the example of FIG. 3) indicating that the reproduction is restricted is assigned (S206). When it is not a regulation object at Step S205 (No), processing of Step S206 is not performed.

  The message number registered in step S203 is registered in the priority reproduction message number list (FIG. 5) for the telephone set matched in step S204.

  When the message number is registered in the priority playback message number list (FIG. 5), display processing with priority playback message is executed (S208), and special visual / audible display is given to the telephone by the priority playback message presence / absence display means F48. Etc. are displayed, and the process ends.

  Note that the processing after step S204 is performed for all telephones, and separate processing results are obtained for each telephone.

  Next, the flow of the message playback process on the key telephone main device 10 side in the above embodiment will be described with reference to FIG. In addition, in FIG. 7, the order of each step shows an example, and may be arbitrarily changed within a range in which the operation / effect is not changed. Further, in FIG. 7, the playback end operation from the telephone side is not specified, but when the playback end operation is received from the telephone side, the processing is ended.

  First, the received data analysis means F49 analyzes whether or not the pressing information of the priority playback button 28 of the telephone has been received (S301), and if received (Yes), the priority playback control means F51 determines the priority playback for the telephone. It is analyzed whether the message number is registered in the message number list (FIG. 5) (S302). If there is no registration (No), playback is impossible and the process returns to step S301. If registered (Yes), the message corresponding to the message number is reproduced based on the priority reproduction message number list (FIG. 5) for the telephone (S303).

  When the reproduction process in step S303 is started, the priority reproduction control means F51 deletes the corresponding message number from the priority reproduction message number list for the telephone (S304).

  In order to continue the reproduction, the priority reproduction control means F51 analyzes whether all the message messages in the priority reproduction message number list for the telephone have been reproduced (S305), and if all have been reproduced (Yes), the process is terminated. To do. If not all have been played back (No), the process returns to step S303 and the process is continued.

If the information on pressing the priority playback button 28 on the telephone cannot be received in step S301 (No), it is analyzed whether the information on pressing the normal playback button 29 on the telephone is received (S306). ), The migration control means F47 analyzes whether the message number is registered in the recording information list (FIG. 3) of the entire system (S307). If there is no registration (No), playback is impossible and the process returns to step S301. If registered (Yes), the reproduction process is started from item number 001 based on the recording information list of the entire system (FIG. 3) (S30 8 ).

  In the case of normal playback, if the other party has registered priority playback and the normal playback is restricted, and the phone being operated does not register priority playback, the message is played. Is regulated. The restriction process is realized by the processes after step S309.

In step S309, the transition processing means F47 checks whether or not the message to be reproduced is subject to normal reproduction regulation against the recording information list (FIG. 3). The process is executed (S31 1 ). In the recording information list (FIG. 3), “S” in the normal playback restriction column corresponds to the normal playback restriction target.

  If it is restricted in step S309 (Yes), the transition processing means F47 continues to analyze whether the other party is registered in the specific person list (FIG. 4) for the telephone being operated (S310). In the case of a registered partner (Yes), since it is no longer a restriction target, the reproduction process is executed as it is (S311).

  If the other party is not registered in step S310 (No), the subject is restricted, and the reproduction of the message is skipped (S312).

  In order to continue the reproduction, the migration processing means F47 analyzes whether all the message messages in the recording information list have been reproduced (S313), and if all have been reproduced (Yes), the process ends. If not all have been reproduced (No), the next reproduction process is started (S314), the process returns to step S309, and the processes of steps S309 to S313 are repeated.

  Next, the flow of the message deletion process on the key telephone main apparatus 10 side in the above embodiment will be described with reference to FIG. In addition, in FIG. 8, the order of each step shows an example, and may be arbitrarily changed within a range in which the operation / effect is not changed. Further, in FIG. 8, the playback end operation from the telephone side is not specified, but when the playback end operation is received from the telephone side, the processing is ended.

  During the message replay process (S401), the received data analysis means F49 analyzes whether the telephone erasing operation has been received (S402). If not received (No), it continues to wait for reception. When the telephone erasure operation is received (Yes), the migration processing means F47 analyzes whether the message message currently being reproduced is a message number existing in the priority reproduction message number list (FIG. 5) for each telephone (S403). .

  If it is determined in step S403 that the message number is present (Yes), the message is not reproduced on the telephone to be preferentially reproduced (there may be a plurality of telephones), so the deletion is regulated. The erase operation is invalidated (S404).

  If the message number is not an existing message number (No) in step S403, the message has been reproduced on the telephone to be preferentially reproduced (there may be a plurality of telephones), or can be deleted because it is not a preferential reproduction message.
