Abstract

PURPOSE:To respond to an incoming from both a transfer original terminal and a terminal to be transferred even after the setting of automatic incoming transfer, and to prevent the release of incomin transfer from being forgotten, by transmitting different incoming sound to both the transfer original terminal and the terminal to be transferred at the incoming to the terminal to be transferred. CONSTITUTION:When an incoming call arrives to a key telephone 1 of the transfer terminal in the state of the automatic incoming transfer is set, this incoming call is transferred to a telephone set to be transferred. In this case, an incoming tone is transmitted to the telephone set to be transferred from an incoming sound trunk 17. Although the incoming tone is transmitted to the transfer terminal and the terminal to be transferred from the different incoming sound trunks 6 and 17, the operation for this case is executed easily by the connection of a time division channel switch 5. Thus, since the terminal to be transferred can transmit the incoming tone also to the transfer terminal after the automatic incoming transfer set, the response is executed from any terminal. Since the in coming tone different from the normal tone is transmitted to the transfer terminal, the release of the incoming transfer being fogotten is recognized.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention provides a system in which a transfer destination telephone number is specified in advance from a transfer source telephone, and all subsequent calls to the transfer source are automatically (This is the number of the automatic call transfer system at the telephone exchange where calls are received.)

[Technical background of the invention and points of interest]

Recently, with the electronicization of telephone exchanges, there has been a tendency for a variety of services to be provided.One such service is the above-mentioned automatic call forwarding system.

That is, such a system C'! As an example of actual use, if a conference is held away from your desk, for example, if you automatically forward calls from your desk phone to the conference room phone number, future calls will automatically be transferred to the conference room. It is used for things like transfer.

Conventionally, such an automatic call transfer system has been constructed in six telephone exchanges as shown in FIG. 1. In this case, telephone exchange@C represents an electronic private branch exchange. In Fig. 1ζ, 1 is a telephone number 1, such as an electronic key telephone, 2 is a communication line and data line connecting the key telephone 1 and the main body of the exchange, 3 is a key telephone line circuit, 4 is a voice communication circuit, and 5 is a time division 6 is a trunk which is a ring tone generating means; 7 is a central control unit t; and 8 is a main storage device.

9 is a signal @ between the line circuit 3 and the central control device 7;

1011 Communication path Control line for communication path switch 5.

11 is a data transmission line between the central control unit 7 and the main storage unit 8; Although the electronic key telephone 1 can be replaced with a dial type 1-talk machine, the key telephone 1 is used here because it is easy to operate. Such a key telephone l is constructed as shown in FIG. In the figure, 12 is a handset, 13 is a dial key, and 14 is a function key used for automatic call transfer. □・ However, if you press the function key 14 to set automatic call forwarding using key telephone l#c and notify the central control unit [i17] that you want to set a call forwarding destination, the central control unit 7 will press the function key 14 to set automatic call forwarding. The lamp (not shown) of the key telephone 1 corresponding to No. 14 ζ is blinked to respond to Cζ. Next, dial key 1 from key telephone l.
3, enter the dial number of the forwarding destination, and then press the function key 14 again to start automatic call forwarding. The central controller 7 turns on the flashing lamp as a response to the automatic call forwarding OK. let This lamp lights up to indicate that the connection is being made while automatic call transfer is being performed. Thereafter, when a call is received at the transfer source key telephone 1, the call is automatically transferred to the telephone set having the transfer destination dial number. In this case, a ring tone is sent from the ring tone trunk 6 to the transfer destination telephone to notify that a call has arrived, but a ring tone to the transfer source key telephone l is not sent. , : Here, Kakamine □Main memory in automatic call forwarding:・1
How to set data at position 8 and central control unit ft7
The flow of the 1-call transfer process is shown in FIGS. 3 and 4, respectively. That is, in the table shown in FIG. 3, the relative address (0-n) is equal to the telephone terminal number (different from the dial number) lc, and each
A memory of l words is provided for each machine. A flag 15 is provided at the end of each word to indicate whether or not the telephone is in automatic call forwarding, and the remaining data indicates the forwarding destination telephone number 16.

Further, in the processing flow shown in FIG. 4, when the central control unit 7 receives all digits of the key dial from the key telephone 1, it calculates the number of the incoming telephone from the dialed number. Based on this number, it is determined from the table in Figure 113 whether the incoming telephone is in automatic call forwarding or not, and if it is in automatic call forwarding, the dial number of the forwarding destination is read from the table and the forwarding destination telephone number is determined. When the call is requested, the communication path switch 5 with the ring tone trunk 6 is closed and the ring tone is sent, and if the call is not automatically transferred, the ring tone is directly sent to the receiving telephone.

According to such an automatic call transfer system, it is possible to perform a good automatic call transfer, and it can greatly contribute to improving the service of the exchange.

However, such a system has the following drawbacks. First, if you set automatic call forwarding, all subsequent calls will be forwarded immediately. This may cause the call to be transferred to a conference room where no one is present, even though the user is still at his or her desk before going to the conference room. Also, lI24ζ is that the user forgets to cancel the call forwarding when returning to his or her desk from the call forwarding destination. This means that even if there is an important call, there is a risk that all calls will be transferred to a destination where no one answers the call.

[Purpose of the invention]

This invention was made to eliminate the above-mentioned drawbacks, and provides an automatic call forwarding system that can answer incoming calls from either the forwarding source or the forwarding destination, and can prevent call forwarding from being forgotten. The purpose is to

[Summary of the invention]

This is a system that allows incoming calls to the forwarding source to be automatically delivered to the forwarding destination by specifying the forwarding destination's Analects number from the forwarding source in advance. I'm trying to send it out.

〔Effect of the invention〕

Even after automatic call forwarding is set, incoming calls can be answered from either the forwarding destination or the forwarding source, and forgetting to cancel call forwarding can be prevented, thereby further increasing the effectiveness of automatic call forwarding.

[Implementation sequence of the invention]

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

Here, the same parts in FIG. 5 as in FIG. 1 are given the same reference numerals. In this case, a trunk 17 is connected to the first communication path switch 5 as a ring tone generating means.

This trunk 17 will send a ringtone to the transfer source when the call is forwarded.
alfjt6b(7)t", 1189)"W76(
7) lHlf & 111 Ring tones with different frequencies or intervals are generated.

The rest is the same as in FIG. 1, so the explanation here will be omitted.

Next, its effect will be explained.

Now, to set automatic call forwarding on the key telephone 1, use the function key 14 to call up the central control unit, enter the forwarding destination dial number, and then press the function key 14 as described above. Automatic call forwarding is set by operating 14 again.

In this state, if the transfer source key telephone 1 receives a call from now on, the call will be transferred to the telephone set having the transfer destination dial number. In this case, a ring tone is sent to the transfer destination telephone from the ring tone trunk 6, and at the same time, a ring tone is sent to the transfer source key telephone 1 from the ring tone trunk 17.

Here, different trunks 6 are used for the transfer source and the transfer destination.
．． An incoming call ':' sound is sent from 17, and the operation at this time can be easily performed as an OT function by connecting the time division communication switch 5. 1
Therefore, if you do this, after setting up automatic call forwarding, you can send the ring tone to the forwarding destination as well as the forwarding source, so that both the forwarding destination and the forwarding source can answer the incoming call. As a result, it is possible to respond from one's own seat to an incoming call immediately after setting the incoming call forwarding, and it is possible to prevent no response at the forwarding destination. Additionally, you can send a different ringtone to the forwarding party, so even if you return to your desk and there is no longer a need for call forwarding, you can answer from your seat, and you will know when you have forgotten to cancel call forwarding. It is also possible to reliably prevent people from forgetting to cancel automatic call forwarding.

[Other examples of the invention]

The present invention is not limited to the above-mentioned embodiments, but can be implemented with appropriate modifications within the scope without changing the gist. For example, in the above description, a separate ringing tone trunk 17 is provided to send the ringing tone to the transfer source, but one ringing tone trunk 6 may be used in common). In this case, the same ringtone will be sent to both the forwarding destination and the forwarding source, but if the forwarding source is informed by some means that the call is set for call forwarding, it is possible to prevent forgetting to cancel call forwarding. I can do it. Of course, the shared ringtone trunk may be modified to generate different ringtones. Furthermore, although the ringing trunk is provided independently in the above description, it may be omitted depending on the type of exchange. Furthermore, the present invention can be applied to various types of exchanges such as digital exchanges.
