Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic dialing method using a personal computer, and more particularly to an automatic dialing method for making a callable state after confirming that the other party's model for a call is a telephone.

[0002]

2. Description of the Related Art Conventionally, there is a telephone device with a modem provided with a switching circuit for switching a non-telephone function by a personal computer or the like and a telephone function by a telephone. In such a device,
For example, dialing is automatically sent according to the telephone number list created on the personal computer, the call is made with the other party, and in the case of non-telephony communication, it is automatically connected to the personal computer side and calls are made one after another according to the list. A method of doing so has been proposed (see, for example, JP-A-62-56067).

[0003]

According to the above-described conventional list transmission method, when control information (operation designation information, channel information, dial information) is sent from the personal computer to the control unit, dial transmission is automatically performed. When the telephone communication is instructed by the channel information, the telephone is connected to the call channel and the call is automatically enabled. Thus, it is a very effective method when making a large number of calls according to the list.

However, the above method is based on the assumption that the other party answers by telephone, and does not consider the case where the other party answers by the personal computer. That is, when the other party responds with a personal computer when telephone communication is instructed by the channel information, a situation in which a call cannot be made occurs.

An object of the present invention is to provide an automatic dialing method for making a call state after confirming that the responding party is a telephone when making a list call.

[0006]

In order to achieve the above object, according to the invention of claim 1, in a method of automatically dialing a destination by referring to a telephone number list, a personal computer dials a network control unit. When the network control unit transmits the dialed number to the communication network and does not detect the carrier and answer tone within a predetermined time after the other party of the number goes off-hook, the network control unit It is characterized in that a call is possible with the other party.

According to another aspect of the present invention, when the network control unit detects an on-hook, or when a carrier or answer tone is detected within a predetermined time after the other party goes off-hook, the network control unit is operated from the personal computer. A new dial number is sent to the network control unit, and the network control unit sends the dial number to the communication network.

[0008]

Operation: The personal computer reads out the customer management ledger file, displays it on the display device, and selects the counterparty to trade with the keyboard and mouse. The automatic dial processing unit in the PC automatically dials the selected destination. After dialing, the network control unit monitors for a predetermined time after detecting no ringing tone, disappearance of ringing tone, or polarity reversal, and detects that there is no carrier and no answer tone, so the partner terminal is not a personal computer. Then, the telephone line is connected to the telephone and the telephones talk with each other. In addition, the automatic dial processing section in the PC can be used when the other party is busy or the other party does not go off-hook.
Automatically dial the next party.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a block diagram of the present invention.
Is a personal computer equipped with an automatic dial processor 12,
A display device for displaying a telephone number list, customer information and the like, 3 is a keyboard 4, 4 and mouse, 5 is a customer management ledger file in which detailed customer information, telephone numbers and the like are stored,
6 is an RS-232C interface unit 7 and a modem 8
For example, a modem phone 10 including a network control unit 9 including a microprocessor, 10 is a telephone, and 11 is a telephone line. Then, the network control unit 9 connects the modem 8 and the telephone line 11 at the time of automatic dialing, and when the other party answers by telephone after dialing, the telephone line 11 and the telephone set 1 are connected.
It is configured to connect with 0.

The operation of this embodiment will be described below. The personal computer 1 reads out the customer management ledger file 5 according to an instruction from the keyboard 3 or the mouse 4 and displays it on the display device 2. Then, one of the displayed customers is selected by using the keyboard 3 or the mouse 4 in advance. Then, in response to an instruction from the keyboard 3 or the mouse 4, the automatic dial processing unit 12 in the personal computer 1
Automatically dials the selected destination.

FIG. 2 is a processing flowchart of the automatic dial processing section. The telephone number of the other party read from the customer management ledger file 5 is set (step 201).
Next, it is checked whether or not the telephone number of the other party is set, that is, whether or not there is the telephone number of the other party to be processed (step 202), and if there is no other party, the process is terminated. .. If there is a partner, the call goes off-hook (step 203) and dials the partner (step 204). When the other party is busy and a busy tone is detected (step 205), or when the other party does not go off-hook even if the ringing tone exceeds n times (step 206)
After recording the error information in a predetermined area of the automatic dial processing section (step 208), the next partner is set (step 210), and the processing from step 202 onward is repeated.

When the other party goes off-hook when the ringing tone is n times or less without the busy tone being detected, as described later,
By switching the telephone line 11 from the modem 8 to the telephone 10 by the network control unit 9, a call is made with the other party (step 207), and a transaction is made based on the customer detailed information displayed on the personal computer 1. Then, when the call ends and on-hook is detected (step 209), the next partner is set (step 210), and the processing from step 202 onward is repeated.

FIG. 3 is a processing flowchart of the network control section 9 after dialing by the automatic dial processing section. After dialing, the network control unit 9 detects no busy tone (step 31) and detects off-ring tone or polarity inversion for off-hook detection (step 3).
2) By monitoring for a predetermined time (for example, 5 seconds) from the detection and detecting that there is no carrier and there is no answer tone (response signal in personal computer communication) (or there is no carrier or answer tone), It is determined that the partner terminal is not a data terminal such as a personal computer (step 3
3), the network control unit 9 switches the telephone line 11 from the modem 8 to the telephone 10 (step 34) and enables mutual telephone calls.

As described above, in this embodiment, when the personal computer responds, the telephone line 11 is changed from the modem 8 to the telephone 10.
Since it is not possible to switch to, it is possible to avoid the conventional state where a call is impossible. When the other party responds with a personal computer, the error information is recorded in a predetermined area of the automatic dial processing unit, and then the next party is set and automatically dialed as described above.

[0015]

As described above, according to the invention described in claim 1, the carrier and the answer tone are not detected within a predetermined time after the off-hook of the other party.
Since the telephone is connected to the telephone line after confirming that the other party has answered the telephone, it is possible to avoid the non-call state when the other party answers the personal computer as in the conventional case. According to the invention described in claim 2, when the call ends or when the other party answers with the personal computer, it is possible to automatically dial one after another according to the telephone number list.
It is possible to reduce a dial operator's work load for dial operation and prevent a dial operation error.
