Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exchange that centrally accepts incoming calls to a plurality of unregistered subscribers and has a relay transfer processing function in addition to an answering machine processing function.

[0002]

2. Description of the Related Art FIG. 12 is a block diagram of a conventional exchange having an answering machine processing function. In FIG. 12, the exchange 20
Is generally a switch network 11, a subscriber circuit 12 provided on the ingress side of the switch network 11, a trunk 13 provided on the outflow side of the switch network 11, and a necessary switching function for controlling them. And a communication path control device 21 for realizing the above. It is known that a telephone line control device 21 is connected to an answering machine 22 for such an exchange 20 to add an answering machine processing function.

In this exchange 20, when a subscriber inputs an absent registration number from a telephone, the absent registration number is input from the subscriber circuit 12 to the speech path control device 21, and that number is the absent registration number. Then, the telephone number of the subscriber is registered in the absentee registration memory provided in the answering machine 22.

When there is an incoming call to the subscriber circuit 12 or the trunk 13, the telephone number thereof is input to the speech path control device 21.
The call path control device 21 determines whether or not the incoming telephone number matches the absent-call registered number, and if they match, the incoming call is connected to the answering machine 22 and the answering machine 2 is connected.
An absence response message is sent from the memory provided in 2.

When the originator does not go on-hook with respect to this absence message and subsequently sends a message, the speech path control device 21 records the message in the memory provided in the answering machine 22. Then, the subscriber who has registered absentee is notified that the message is recorded, for example, by turning on the lamp of the telephone or a so-called pager, so that the subscriber who has absentee registered later calls the exchange. And read the message.

Although the answering machine 22 is shown as an independent device in FIG. 12, its function is the trunk 1.
There is also known one that is provided in the communication path control device 21 and the communication path control device 21 and integrated.

However, according to the conventional method, when the caller of the caller is in the conference, for example, even when the caller is absent, the caller can respond to the absence message. When he heard that he was absent, he needed to call the other correspondent again.

Further, even when the telephone number of the person leaving the office is indicated by the absence message, the caller hangs up the telephone number once and returns to the telephone number of the person leaving the place in the conventional method. I had to call back. In addition, as a way to handle incoming calls for absentees, certain incoming calls will be forwarded to the away location, but other general incoming calls will simply be recorded. Although there is a demand, the conventional method cannot meet such demand.

If this is realized by the conventional method, a person responds by proxy to select whether a specific incoming call or a general incoming call,
The corresponding measures will be taken. In this case, it is necessary for the proxy answerer of the telephone to always manage the destination of the person leaving the office, and an extra telephone answering work called proxy answer occurs, which reduces the efficiency of the telephone answering. In addition, since various types of terminals such as facsimiles and so-called personal computers are accommodated in the exchange, it is often necessary for these terminals to have an answering machine processing and a relay transfer function similar to telephone calls.

The present invention was created in order to solve the problems as described above, and when an incoming call is made to a subscriber who is absent, a single outgoing call is required not only for answering machine processing but also as necessary. An object of the present invention is to provide an exchange that enables relay transfer processing and enables fine-tuned services according to the circumstances of the calling terminal and called terminal and the usage environment at that time.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 6 is a block diagram of an exchange having the functions of answering machine processing and relay transfer processing according to the embodiment of the present invention. In FIG. 6, the exchange 10 is the same as that shown in FIG.
4, the function of the conventional answering machine 22 is added to the communication path control device 14 or the trunk 13, and the answering machine 21 is omitted, and the communication path control device 14 is provided with various means according to the present invention.

That is, in the present embodiment, the speech path control device 14 is provided with an absentee registration memory as the absentee registration means 1, a voice synthesizer as the absence answering means 2, for example, first to third transfer control means 3a to 3c, There are provided first and second message recording means 4 and 7, response monitoring means 5, non-response notifying means 6, first and second identification information registration means, number information registration means and determination means.

Here, the exchange 10 is a subscriber line exchange that accommodates a plurality of subscribers in the public telephone network, or a private branch exchange (PBX) that is connected to the public telephone network and accommodates a plurality of extension telephones. Further, the exchange 10 is assumed to be connected with a push line using a push button, a digital subscriber line, etc., but a DTMF (Dual Tone Multiple
Frequency tone can be transmitted. In addition to the telephone, various terminals such as a facsimile and a so-called personal computer are connected to the exchange 10.

The contents of the answering machine processing and the relay transfer processing executed by the exchange of the present invention configured as described above will be described below with reference to FIG.
This will be described with reference to FIGS. For convenience of description, the description will focus on the case where the terminal is a telephone. FIG. 7 is an operation flowchart of the embodiment of the invention described in claims 1, 5, and 9. In FIG. 7, in S01, the subscriber number and extension number (hereinafter referred to as “first number”) are registered in the absence registration memory by the method described above. At that time, when using a message for answering, simply use the message “Absent” or the message “Absent” as the number information of the receiving terminal (phone) of the relay transfer destination. A selection is made whether to include a number (hereinafter referred to as "second number").

That is, according to the present invention, the answering message is basically a message notifying that the caller is absent, since it is sufficient that the person making the call can recognize that the response as a result of the call is an absence message. If the calling terminal is a telephone, it may be a DTMF tone that the caller can recognize, or if the calling terminal is a facsimile, the signal can be recognized by the facsimile.

In the case where the terminal is a telephone, it is possible for the caller to know whether the caller's requirement is to be the absentee or if another person is substituted. In some cases, it is desirable to leave it to the caller's judgment as to whether or not to perform the relay transfer to or to perform the relay transfer and the incoming call connection. Therefore, if the answer message is a message,
The message may simply be a message that the user is absent, or may include the second number. In the former case, the second number is arbitrarily selected by the caller of the telephone. In the latter case, the second number is also registered at the time of absence registration. The second number may be any number such as an abbreviated dial number that allows the other exchange to recognize the called terminal (telephone) of the relay transfer destination.

In S1, when there is an incoming call in the subscriber circuit 12 or the trunk 13, the call path control device 14 refers to the absentee registration memory and the telephone number of the incoming call coincides with the first absent registered number. It is determined whether or not there is an incoming call to the telephone with the registered absent telephone number.

In step S2, when the call path control device 14 detects an incoming call to the telephone set of the registered absent telephone number, it sends an answer message to the subscriber line or the interoffice relay line via the corresponding subscriber circuit 12 or trunk 13. Send out. In S3, the communication path control device 14 determines whether or not the second number is input from the caller without being on-hook until an appropriate time elapses after the absence response is sent. The input of this second number is performed when the caller has previously been notified of the second number by the absentee, or when the requirement is to replace another person (in this case, the second number is the caller). In many cases, it is not necessary to wait for the end of the absence response, so it may be input immediately after the absence response is sent.

As a result of the determination in S3, if the second number is not input from the caller (in this case, the caller normally goes on hook), the determination in S3 is negative (NO), and the communication path control device 14 determines The process ends without controlling the connection for the outgoing call. On the other hand, if the second number is input from the sender, S
The determination of 3 is affirmative (YES), the process proceeds to S4, the incoming call is relay-transferred to the telephone of the second number designated by the caller, and the connection control is started. The relay transfer of this second number is
When the transfer destination telephone is in another station, it is carried out via a telephone line or, when a register trunk is available, via a signal line.

Next, in S5, the communication path control device 14
Monitors the call path and determines whether or not there is a response from the relay transfer destination telephone. This judgment is made based on, for example, the number of ringing tones and busy sounds, time, and the like. If it is determined that there is a response as a result of the determination in S5, the determination in S5 becomes affirmative (YES), and the call path control device 14 maintains the call path formed because the incoming call connection for the caller was successful. To end this procedure.

On the other hand, as a result of the determination in S5, if it is determined that there is no response, the determination in S5 becomes negative (NO), the process proceeds to S6, and the communication path control device 14 indicates that there is no response to the caller. When the other party sends out a message indicating that the other party is busy and the caller sends out a message, the message is recorded and the processing for the outgoing call is terminated. As described above, in the first embodiment, the caller of the telephone does not need to repeat the on-hook / off-hook operation to make a call again even when the other party is absent.
You can complete the message by specifying the transfer destination with one off-hook operation.

Next, FIG. 8 is an operation flowchart of the embodiment of the invention described in claims 2, 5, and 9. The same processing as that of FIG. 7 showing the operation of the first embodiment includes
The same reference numerals are given. Hereinafter, different parts will be mainly described. In FIG. 6, the process of S13 is added in the second embodiment. That is, since the caller who recognizes that the other party is absent from the answering machine response (S2) sends the message before sending the second number (S3), the message sent from the caller is sent. Record (S1
3). After that, the same processing as that of the first embodiment is performed.

In the second embodiment, the message of the sender is recorded also in S6, but the recording in this case is significant when the transfer partner is different from the partner of the first number. Next, FIG. 9 is an operation flowchart of the embodiment of the invention described in claims 3, 8 to 7, and 9. The same reference numerals are given to the same processes as those in FIG. 7 showing the operation of the first embodiment. Hereinafter, different parts will be mainly described.

In FIG. 9, in the third embodiment, S02 is replaced with S02 as the absence registration process, and S2 is executed.
Process 3 is added. That is, in S02, in addition to registering the subscriber number, the extension number, and the response message as necessary in the absence registration memory, as in S01, the identification information is also registered. This identification information is "unique identification information" for each registered absentee or "common identification information" for the registered absentee. A plurality of these are prepared, and the dates and days on which they are valid are registered in association with the "unique identification information" and "common identification information".

The caller who recognizes that the other party is absent from the answering machine response (S2) sends the second number (S).
Since the identification information is sent prior to 3), it is determined whether the identification information is input from the sender (S23). After that, the same processing as that of the first embodiment is performed. This S2
If no input of "unique identification information" or "common identification information" is detected from the sender in step 3, S23
The determination is negative (NO), and the process ends without performing connection control for the outgoing call.

Here, "not detected" means that the caller is not on-hook except when the caller is on-hook.
When there is no input of information from the sender, some information has been input from the sender, but there is no match between the information and "unique identification information" or "common identification information". On the other hand, if any of the "unique identification information" and "common identification information" input from the caller is detected without being on-hook, the determination in S23 is affirmative (YES), and the call path with the caller is Is maintained as it is, in preparation for the input of the second number (S3) from the sender. After that, the first
Processing similar to that of the embodiment is performed.

In the third embodiment, the sender who inputs the "unique identification information" is often informed by the person who registered the absence of the "unique identification information".
Due to the transfer of the number to the telephone, the outgoing call is likely to be relayed to the person who registered the absence. On the other hand, since it is considered that the caller who inputs the "common identification information" does not want to talk with a specific person, the relay transfer to the telephone with the second number can achieve the temporary purpose.

Next, FIG. 10 is an operation flowchart of the embodiment of the invention described in claims 4-9. 7 and 9 showing the operation of the first and third embodiments are designated by the same reference numerals. Hereinafter, different parts will be mainly described. In FIG. 10, in the fourth embodiment, S03 is replaced with S03 as the absence registration process, and the process of S34 is added to the process of S23.

That is, in S03, in addition to registering the subscriber number, extension number, and response message in the absence registration memory as necessary, as in S01, the identification information is also registered in the same manner as in S02, and further registration is performed. The transfer destination telephone number is registered for each "unique identification information" of each absentee, and the transfer destination telephone number is registered in advance for the registered absentee "common identification information".

When the identification information is input from the caller (S23), the call is transferred to the second telephone number registered in advance (S34). After that, the same processing as that of the first embodiment is performed. Therefore, in the fourth embodiment,
The features of the third embodiment can be further clarified. That is, the caller who inputs the "unique identification information" can surely make a call with the person who is registered as absent at the transfer destination. On the other hand, the caller who inputs the “common identification information” can talk with a predetermined respondent and can surely achieve a tentative purpose.

Next, FIG. 11 is an operation flowchart of the embodiment of the invention described in claims 2, 4 to 8. FIG.
In S1, in S03, in addition to registering the subscriber number, extension number, and response message in the absence registration memory as required in the same manner as S01, the identification information is also registered in the same manner as in S02, and the registered absence is registered. "Unique identification information" for each person
To the telephone number (second
No.) is registered, and the telephone number (second number) of the relay transfer destination telephone is also registered in advance for the registered absentee with respect to “common identification information”.

In step S1, when there is an incoming call (first telephone number) in the subscriber circuit 12 or the trunk 13, the call path control device 14 refers to the absentee registration memory and determines that the incoming telephone number is the absentee registered number. It judges whether or not they match, and detects an incoming call to the telephone set of the registered absent telephone number.

In S2, when the call path control device 14 detects an incoming call to the telephone set of the registered absent telephone number, it sends an answering message to the subscriber line or the interoffice relay line via the corresponding subscriber circuit 12 or trunk 13. Send out. And answer (S2)
Then, it is determined whether or not the identification information is input from the sender who recognizes that the other party is absent (S23).

If no input of "unique identification information" or "common identification information" is detected from the sender in S23, the determination in S23 is negative (NO), and S
Proceed to step 13 to record the message of interest sent from the sender. After that, in the present embodiment, it is assumed that the connection is terminated without controlling the connection for the outgoing call. On the other hand, from the sender, "unique identification information" or "common identification information"
If any of the inputs is detected, the determination in S23 becomes affirmative (YES), the process proceeds to S34, the call is transferred to the second number registered in advance, and the connection control is started.

For example, if the exchange 10 is a PBX,
A person who leaves the conference (away person) A answers only the call from a specific person (specific person) B in the meeting room, and the call from other unspecified person (unspecified person) Assume a case where you want to complete the record of the requirement. In this case, the away person A conveys his "identification information" to the specific person B, registers his "extension number" and "identification information", and at the same time, the telephone number of the telephone in the conference room ( 2 number) is registered (S02).

When the specific person B and the unspecified person C call the away person A, since the away person A is registered as absent person, an absence response is sent to each of the specific person B and the unspecified person C. (S1, S2). The absence response in this case is simply a message of absence or a DTMF tone. The specific person B who has heard the absence response can send the “identification information” because the away person A has previously taught the “identification information”. On the other hand, the unspecified person C who has heard the absence response cannot send it because he does not know the “identification information”.

Therefore, in the determination of S23, the determination is negative (NO) with respect to the outgoing call of the unspecified person C. Therefore, it is monitored whether or not the unspecified person C inputs the message without being on-hooked. If a message is input, it is recorded (S13), and this procedure is completed. On the other hand, with respect to the outgoing call of the specific person B, the determination in S23 is affirmative (YES), so the outgoing call of the specific person B is transferred to the telephone number of the conference room registered in advance by the away person A (S34). ), End this procedure.

Therefore, in the fifth embodiment, a specific incoming call is transferred to the away location to respond to the incoming call, but other general incoming calls are simply recorded as a message. Can be easily met.

[0056]

As described above, according to the invention described in claim 1, the relay transfer destination (incoming terminal) is specified by the number information to be transmitted while maintaining the communication path formed by the calling terminal when the other party is absent. Then, since it can be relay-transferred to the called terminal, the calling terminal can achieve the calling purpose with one calling operation without redoing the calling operation when the other party is absent.

According to the second aspect of the invention, when the other party is absent, the message to be sent is recorded while maintaining the communication path formed by the calling terminal, and the incoming call designated by the number information sent subsequently is recorded. Since it is possible to relay and transfer to the terminal, the calling terminal left one application message because the other party is absent, but if it is necessary to call another terminal subsequently, 1 It is possible to achieve the calling purpose by calling once.

According to the third and fourth aspects of the invention, when the other party is absent, the calling terminal is requested to input the identification information while maintaining the formed communication path, and the calling terminal inputs the identification information. In this case, the call can be relayed to the call receiving terminal designated by the caller terminal by the number information or the call receiving terminal having the number information registered in advance. Therefore, it is possible to select / designate the calling terminal that responds from the viewpoint of the subscriber who is absent, and select / designate the receiving terminal of the relay transfer destination.

For the same purpose, as the identification information, a plurality of identification information unique to the absent registration subscriber or common identification information is prepared,
Further, a plurality of number information is prepared and switched according to the date and time and the day of the week (the invention according to claims 6 to 8). Therefore, it is possible to flexibly meet various needs. In the invention according to claim 9, when the response from the called party to the outgoing call relay-transferred cannot be detected, the fact is notified to the calling terminal and the message of the calling terminal is recorded. At the terminal, one call operation can be performed without repeating the complicated call operation, and when the relay transfer destination is also absent, the message can be surely transmitted, and a good telephone response service can be received. .

Next, the number information can be arbitrarily selected while the calling terminal is off-hook (invention according to claims 1 to 3) and is prepared on the exchange side (claim 8). In addition, it is possible to easily make a call to another place / person without calling again. When the transfer destination is in another station, the number information can be transferred to the other station via the telephone line or the signal line, that is, if the exchange can recognize the number information. Since it is good, existing facilities and functions can be effectively used.

Moreover, the answering machine need not only be a message, but a signal or the like that can be handled by the exchange can be arbitrarily selected and used as long as it can simply notify the absence of the other party. Therefore, according to the present invention, since it is not necessary to call again when the other party is absent, it is possible not only to reduce the call volume but also to provide a flexible answering service that considers the convenience of both the calling terminal and the called terminal. An exchange having a processing function and a relay transfer function can be realized.

Moreover, since the existing facilities and functions can be effectively utilized, it is possible to provide an economical exchange.
