Abstract

PURPOSE:To increase the rate of annunciation completion of a message and to improve serviceability by re-calling an extension telephone set a specific time later in case of a failure in message transmission and trying resending the message. CONSTITUTION:A control part 30 compares the current time with desired call time registered by a registration control means 31 for registering the desired call time by a time comparing means 32. Then when the current time coincides with the desired call time, a call control means 33 calls a corresponding telephone set and sends out the message. If the message can not be sent by the 1st call of this call control means 33, a re-call control means 34 makes a re-call a specific time later and tries resending the message. Further, if the message can not be sent out even by this re-call control means 34, a display recording control means 35 prints out the reason and time of the failure in message transmission on a printer 70 together with the extension number.

Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to an improvement in a private telephone exchange equipped with means for automatically sending messages, such as wake-up calls.

[Technical background of the invention]

Conventionally, this type of exchange has a main body 1 consisting of a switching circuit 11, a central office line circuit 12, a voice response circuit 13, and a subscriber circuit 14 provided for each extension telephone 812, as shown in FIG. A control unit 3 having a call control function,
A storage section 4 for storing the calling time, the number (extension number) of the extension telephone 2, etc., and a timer 5 for measuring the current time are each provided. Note that 6 is a central office line.

When registering a call time in such a configuration, the call time is designated from the extension telephone tIA2 according to a predetermined dialing procedure. Then, the exchange transmits the signal of the above-mentioned calling time to the control unit 3 via the subscriber circuit 14, and the control unit 3 stores the above-mentioned calling time in the storage unit 4 together with the extension number of the extension telephone 12 that made the registration request. do.

On the other hand, during normal operation, the control section 3 reads out the calling time stored in the storage section 4 at regular time intervals, compares it with the current time of the timer 5, and when the two times match, calls the corresponding extension telephone 2. . When the extension telephone responds to this call by going off-hook, the voice response circuit 13 sends out a predetermined voice message via the switching circuit 11 and the subscriber circuit 14, respectively. Thus, for example, a wake-up call is automatically made to each extension telephone 2.

[Problems with background technology]

However, in general, such conventional call service switchboards with early call function cannot send messages if, for example, the extension telephone 2 does not answer or is busy, or if a so-called line lockout occurs due to the handset being disconnected, etc. It was determined that it was impossible to send the message and gave up on sending the message. For this reason, troubles such as messages not being broadcast even though the time has been registered tend to occur, resulting in poor serviceability. In addition, if a message cannot be broadcast, even if the user who registered for the call makes an arrangement, it is not possible to clearly answer the reason why the message could not be broadcast, and business operations are interrupted. This was extremely undesirable as it could interfere with operation.

[Purpose of the invention]

The present invention aims to improve serviceability by increasing the completion rate of message broadcasting, and when a message cannot be broadcast, information regarding the failure to broadcast can be left as a recorded result, thereby facilitating smooth business operations. Premises N
The purpose is to provide a telephone exchange.

[Summary of the invention]

In order to achieve the above object, the present invention attempts to resend the message by re-ringing the extension telephone after a certain period of time when the message cannot be sent, and this re-ringing is repeated a predetermined number of times. When a message could not be sent, the reason, time, and other information about the failure to send a message were recorded on recording paper along with the identification information of the extension telephone.

[Embodiments of the invention]

FIG. 1 shows the configuration of the main parts of a private branch exchange according to an embodiment of the present invention, in which 30 indicates a control section, 40 indicates a storage section, and 50 indicates a timer.

The control unit 3o includes a registration control means 31 for registering the desired call time, a time comparison means 32 for comparing the desired call time registered by this means 31 with the current time, and a time comparison means 32 for determining the desired call time. When matches the current time,
There is a call control means 33 that calls and sends a message to the corresponding telephone number, and when the Q call control means 33 fails to send a message in the first call, it calls again after a certain period of time and sends a message. When the message cannot be sent even by the recall control means 34 which tries to send it again and this recall control means 3"+4, the reason why the message could not be sent and the time and time are displayed in 7 links along with the extension number. It has a display/recording control means 35 for printing out data on the computer 70.

The storage unit 40 includes tables B and A that store the desired call time input by the registration control means 31 and the extension number of the extension telephone that registered the desired call time in corresponding storage locations, and It is composed of a table DF3 and a table C which respectively store the time and extension number when a message cannot be sent due to a re-call by the call control means 34.

The timer 50 includes a timer A that measures the current time, and a timer B that measures the time when a timing instruction is issued from the control section 30.

Next, the control unit 3 controls the operation of the exchange configured as described above.
This will be explained according to the control procedure of No. 0. Furthermore, now table A,
Figure 2(a) is shown in B, respectively.

(As shown in b>, it is assumed that extension numbers XXX, YYY, . . . and desired call time 42, . . . are stored.

During normal operation, the control unit 30 first specifies the address of table B in step 3a, reads out the desired call time in step b, and sets this desired call time to timer A in step 3C, as shown in FIG. 3(a). It is compared with the current time inputted from step 3d. If the desired call time does not match the current time, the time comparison operations from step 3a to step 3d are repeated.

Now, in step 3d, for example, if the desired calling time A matches the current time, the control unit 30 first reads the extension number XxX of the extension telephone in which the desired calling time has been registered from table A in step 3e, and then in step 3f A call is made to the extension telephone using well-known procedures. When this call control is completed, the first address S of tables A and B is cleared in step 3g, and the value of the address counter is shifted to the next value, and then, in step 3h, the status of the extension telephone in response to the above call is determined. Let's do it.

If this happens, there will be 4! If the telephone is ringing, the control unit 30 starts timer B in step 31 as shown in FIG. If the extension telephone goes off-hook and responds before it is determined that the time has elapsed, the process moves to step 3k, and a predetermined voice message, which has been set in advance in step 3, is sent to the extension telephone, thereby providing a wake-up call, for example. Do the following.

On the other hand, the other party does not notice the above call and steps 3λ
If it is determined that the time has expired in step 3h, or
If it is determined that the extension telephone is busy or the line is locked out, the controller 130 determines in step 3m whether the above call is the first ring or a re-ring, and If it is a call, proceed to step 3n, where a certain time (for example, 3 to 5 minutes) is added to the current time to obtain a re-call time, and this re-call time and extension number are set in tables B and A, respectively. . and step 3
0, the recall flag corresponding to the extension telephone set is set, and then the process returns to the time comparison operation in steps 38 to 3d.

Now, if the above-mentioned re-calling time coincides with the current time in this comparison operation, the control section 30 calls the extension telephone again in steps 3e to 3g in the same way as the first ringing operation described above. , the state of the extension telephone is determined in step 3h. If it is determined in this judgment that the telephone is ringing, the off-hook monitoring of the extension telephone is carried out in steps 31 and 32, and if the other party notices this re-ringing and responds by picking up the handset, the voice is heard in step 3. Sends a message.

On the other hand, if the other party does not notice this re-call, or the line is busy or the line is locked out, the control unit 30 determines whether the above-mentioned call is a re-call from the set state of the recall flag in step 3m. If it is a re-call, the process moves to step 3p. First, in this step 3p, the current time and extension number are stored in table D.
, C, and then in step 3q the printer 70
The extension number and time stored in the above tables C and D,
Furthermore, the reason why the message could not be reported is output as notification failure information and printed out.

FIG. 4 shows an example of the print result. After completing the printout of the non-notification information, the controllers i81!30 clear the recall flag and tables C and D, respectively, in step 3r, and then return to the time comparison operation in steps 3a to 3d.

Thereafter, the above operation is repeated every time the desired call time coincides with the current time in the time comparison operations in steps 3a to 3d.

In this way, in this embodiment, if the message cannot be sent on the first call, the call is made again after a certain period of time and an attempt is made to send the message. Even if the user is far away and does not notice or is busy, the message can be broadcast with high probability, thereby improving serviceability. Furthermore, if the message cannot be broadcast even after re-calling, the time, extension number and reason are printed out on the printer 70 as notification failure information. As a result, troubles with call registrants can be reduced and business operations can be carried out smoothly.

Note that the present invention is not limited to the above embodiments. For example, in the embodiment described above, the non-notification information is printed out after the second call, but the printout may be performed after the third or more call. Furthermore, the information that cannot be reported to be printed out may be displayed on a display device or the like at the same time.

Furthermore, the calling time may be inputted together with the extension number of the extension telephone from an input means (not shown) of the control section 30. In addition, the control procedure and control content of the control unit, the type of recording means, the content of non-notification information, the type of message, etc. can be modified in various ways without departing from the gist of the present invention.

〔Effect of the invention〕

As described in detail above, according to the present invention, when a message cannot be sent, the telephone extension is called again after a certain period of time to try to send the message again, and this call is repeated a predetermined number of times. When a message could not be sent even though the message could not be sent, information regarding the failure to send the message, such as the reason and time, is recorded on a recording paper along with the identification information of the extension telephone, thereby improving the message notification completion rate. To provide a private branch telephone exchange that improves serviceability by increasing the number of messages and, when a message cannot be broadcast, can record information regarding the failure of the message as a record, thereby facilitating smooth business operations. can do.
