Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention allows an external caller to select one of a plurality of arbitrarily set transfer destinations using a telephone (telephone line) to which a voice warp service has been contracted, and to transfer an external call. The present invention relates to a novel method and apparatus for performing the method.

[0002]

2. Description of the Related Art Transfer after answering in voice warp is a kind of telephone transfer service provided by NTT, which is capable of once responding to a telephone call from an outside line and then transferring it to any other external telephone. That is, this service hooks up (self-stops) the own telephone after a call with the outside line, holds the outside line telephone at the office side, calls the transfer destination during that time, calls the transfer destination, and completes the call with the own telephone. When ON is hooked, the hold of the outside line telephone is released, and a call can be made with the transfer destination.

[Problems to be solved by the invention]

[0003] This service has the advantage that it can be transferred to any telephone number in response to a request from an outside line destination, but the receiver must always handle it manually. This means that the service cannot be used if a person who works as a secretary in a small company does not have a telephone number. Also, this service is difficult to use when there is often a secretarial person who can't answer the phone because of other tasks. In such a case, N
Although there are transfer services provided by the TT, in this case, there is an inconvenience that the transfer destination is limited to one place. Of course, the setting of the transfer destination can be freely changed, but the transfer is still performed to a specific one place.

[0004] However, even when working alone,
In some cases, you may want to transfer to one of multiple locations, such as your home, office, or office. However, since mobile phones have recently become widespread, in such cases, transfer to the mobile phone often solves the problem. However, in recent times when the world economy is poor, there are many companies that do not have a secretary or telephone number even if they work with a few people. In this case, it is also difficult to notify the number of each person's mobile phone to many people.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a new telephone system for automatically responding to a case where only one telephone is used (although not limited to one telephone) and a plurality of destinations are required. The present invention provides a simple transfer method and apparatus. The present invention uses a voice warp service currently provided by NTT to allow an external caller to make a call to select a transfer destination. Hereinafter, a transfer method of the present invention and a transfer device embodying the method will be described.

[0006] The transfer method of the present invention takes the following procedure in conformity with a voice warp service (hereinafter referred to as voice warp). First, the post-response transfer function of voice warp is summarized as follows. (1) In response to a call of an incoming external telephone call, after responding to the external telephone line with whom the user wants to talk, the user hooks up (self-stops) his own telephone and holds the external telephone call at the office. Thereby, transmission of the transfer destination telephone number becomes possible. (2) Next, dial the telephone number of the requested transfer destination. (3) Finally, when the user goes on-hook after the call with the transfer destination is completed, the hold of the external line telephone is released, and the call between the external line and the transfer destination becomes possible. As a result, the transfer is performed. (4) If the transfer destination does not respond to the call, hook up your own phone again to release the hold on the outside line,
Tell the outside line to that effect and end the call. Alternatively, if the outside line desires a call with another person, the telephone is hooked again to hold the outside line call, and the same operation is continued to complete the transfer or the call. (5) If the outside line side or the transfer destination side goes on-hook after the end of the call, the own telephone line is released.

On the other hand, according to the present invention, [1] When a bell voltage is received (call from an outside line telephone), a DC loop is closed (forms an OFF hook state) in its own telephone line and recorded in advance. Send a message. This message includes a plurality of pairs of a destination name and the like and a registration number (for example, 01, 02, etc.). Then, when the outside line sends a registration number such as a name for which a call is desired, the PB signal or the DP sound signal is received, and the DC loop of the own telephone line is instantaneously interrupted (hooking). As a result, the outside line is held at the office.
Thereby, transmission of the transfer destination telephone number becomes possible. [2] Subsequently, the telephone number of the transfer destination corresponding to the received registration number is transmitted. The pair of registration number and forwarding phone number is
A plurality of sets are registered in the memory in advance. [3] When the transfer destination goes off-hook, a reception signal such as polarity inversion is sent. When the signal such as the polarity reversal is detected, the DC loop of the own telephone line is closed (on-hook state). As a result, the station releases the hold of the external telephone line, and the call with the transfer destination becomes possible. [4] If the transfer destination does not answer the telephone call, for example, if the polarity inversion does not occur within a predetermined time, the hooking signal is transmitted again to recover the communication state with the external telephone, and the transfer destination does not answer the telephone. Is transmitted, and the DC loop of the own telephone line is released to be in an on-hook state. Alternatively, if the outside line desires a call with another person, the input of the registration number is again waited, the corresponding transfer destination telephone number is transmitted, and the same operation as described above is performed.
The transfer may be completed or the call may be completed. [5] If the outside line side or the transfer destination side goes on-hook after the call ends, the own telephone line is released.

[0008] If necessary, the telephone number of the outside line may be displayed on the transfer destination telephone. For that purpose, a function of recording the received caller number and a function of transmitting the recorded caller number to the transfer destination as an additional number are required. Also, after sending the recorded content to the outside line, the other party's statement is recorded and transmitted to the transfer destination, or based on the other party's statement instead of sending the registration number (01, 02, etc. Rather, variations such as sending out the registration number of the desired transfer destination are also conceivable.

[0009] The name of the transfer destination and the registration number may be recorded from the device embodying the method of the present invention, or from a self-phone of a voice warp contract equipped with the device, or from any external telephone. It may be performed. In the case of recording from a telephone, it is preferable to request input of a recitation number for security. Although there is no particular limitation on the recording means, it is desirable to use an IC recording device that has a simple mechanism and has few failures. There are no restrictions on the number of names and registration numbers to be recorded, but if it is too large, the message lengthens and the outside line gets frustrated, so that about 2 to 6 cases are practical. It should be noted that another telephone in the company can be registered as a transfer destination.

A pair of a registration number and a transfer destination telephone number is registered in a memory. This registration may be performed by the apparatus embodying the method of the present invention, as in the case of the recording, or may be performed by the apparatus. May be carried out via a telephone line from a self-phone of a voice warp contract attached with, or any external telephone.

Next, the apparatus of the present invention which embodies the method of the present invention will be described. The multiple transfer destination selection device after response according to the present invention includes the following main elements. First, [1] a message sending unit that records a message including a plurality of sets of a transfer destination name and the like and a registration number, and sends a message following off-hook. For recording, an IC recording device is preferable. [2] A pair of the registration number and the transfer destination telephone number is registered in a memory, and when a DTMF decoder receives a PB signal or a DP sound signal indicating any one of the registration numbers transmitted from an external telephone, the receiving telephone A telephone number transmitting unit for transmitting a transfer destination telephone number corresponding to the registration number following an instantaneous interruption of a line; [3] A local line monitoring unit that performs reception of a bell voltage, detection of polarity inversion, and the like. [4] DC loop closure and release (or off-hook,
A loop controller that controls on-hook and hooks (hashes). [5] A control unit that controls these. [6] If necessary, a modem signal transmitting / receiving unit may be provided for recording the received caller number of the external line destination and transmitting the recorded caller number to the transfer destination as an additional number. In addition, if a start switch for starting the device is provided, if the secretary etc. can not release it, start this device, and when the hand becomes available, release the start and receive the phone directly The range of application is expanded.
