Abstract

PROBLEM TO BE SOLVED: To call a recipient by providing a call waiting reject service key used for registration at a maintenance terminal to a telephone set and using the key to operate an extension in a call waiting state in one operation. SOLUTION: An exchange 10 uses a maintenance terminal 50 to register a call waiting reject service key 60 to a telephone set 1 to which a call waiting function is set. In the case that the telephone set 1 receives a call from a telephone set 3 while telephone sets 1, 2 make a speech, the exchange 10 uses the call waiting function to send a call waiting state tone(CWT) to the telephone set 1 and a ring back tone(RBT) to the telephone set 3. When the telephone set 1 desires to take precedence of a speech over the telephone set 2, the call waiting reject service key 60 on the telephone set 1 is depressed. Then the call waiting state tone(CWT) sent to the telephone set 1 and the ring back tone(RBT) sent to the telephone set 3 are stopped, a talkie 40 is connected to the telephone set 3 to send a message denoting 'no reply is possible' to the telephone set 30.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a standby system for a call waiting service in a telephone exchange system, and more particularly, to an extension / departure / termination connection in a premises.
It belongs to a call waiting service standby system for performing telephone services such as dedicated line incoming / outgoing connection and office line incoming / outgoing / incoming connection.

[0002]

2. Description of the Related Art In a conventional switching system, a waiting system for a call waiting service includes a call waiting subscriber who disconnects a line even if the call waiting subscriber terminates the call. Some can be called.

[0003] Such a prior art is disclosed in Japanese Unexamined Patent Publication No.
A call waiting service waiting system disclosed in Japanese Patent No. 327891 is known.

[0004] Call waiting in the prior art
The service standby system includes an exchange connected to a plurality of subscribers, a sound source generator connected to the exchange that can generate a plurality of types of sounds, and a control device that performs switching control of the exchanger. , And a memory connected to the control device.

[0005] In the memory, there is provided a subscriber status table for storing whether the subscriber is performing a call waiting service registration or a call waiting standby function.

The system will be described below in detail. An extension telephone is connected to an electronic exchange, and a maintenance terminal (such as a personal computer) registers the presence or absence of a call waiting standby service for each extension. Extension A and extension B are in a call. Extension C arrives at extension A and enters a call waiting state. Extension B is in a call waiting standby state by dial operation or the like. When the extension A ends the call, both the extension A and the extension B are called.

[0007]

However, in the conventional call waiting service standby system, when a call with extension B currently in use is desired to be prioritized,
The incoming extension C is ignored, and the service for the extension C cannot be improved.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a call waiting service standby system capable of operating a call waiting extension by one-touch operation with a key operation to call a called party. is there.

[0009]

According to the present invention, a plurality of telephones, an exchange to which the telephones are connected, a central processing unit and a storage device connected to the exchanges, and a telephone connected to the exchanges. Call waiting service having a maintenance terminal
The telephone set with the call waiting function is provided with a call waiting refusal service key registered at the maintenance terminal, thereby providing a call waiting service standby system.

Further, according to the present invention, there is provided a call waiting service standby system, wherein the exchange is provided with a talker for transmitting a message during a call to the telephone.

Further, according to the present invention, when it is desired to prioritize a call currently in progress during call waiting on the telephone, a callee of the telephone being call-waited by a key operation on the telephone is provided. And a function for transmitting a message to the user and calling the called party by operating the telephone, which has been call-waited by a key operation on the telephone after the call ends.・ Service waiting system is obtained. Is obtained.

[0012]

[Function] If you want to give priority to the call currently in progress during call waiting on the telephone, notify the called party of the extension whose call is being waited by the key operation on the telephone that "the call cannot be answered". To send a message.

After the call is over, the call-waiting extension is operated by one-touch operation of a call-waiting extension by a key operation on the telephone to call the called party.

[0014]

FIG. 1A shows a system configuration of an embodiment of a call waiting (CW) service standby system according to an embodiment of the present invention.

Referring to FIG. 1, call waiting
The service standby system includes a plurality of telephones (extensions) 1, 2, and 3, which are multifunctional telephones, and these telephones 1, 2,
An exchange 1 such as a private electronic exchange to which 3 is connected
0 and the central processing unit 2 connected to the exchange 10
0 and a storage device 30.

Further, the exchange 10 is connected to a talker device 40 for transmitting a message and a maintenance terminal 50 such as a personal computer.

FIG. 1B shows the functions of a plurality of telephones 1, 2, and 3. Each of the telephones 1, 2, and 3 is provided with a display unit that displays numbers and numbers on buttons such as push buttons, and a call waiting rejection service key 60. The call waiting rejection service key 60 is used, for example, when the telephone 1 wants to give priority to a call with the telephone 2.

FIG. 2 shows the memory configuration of the call number information after the end of the call. As shown in FIG. 2, the call number information is stored in correspondence with the multifunctional telephone.

FIG. 3 shows a message sending operation flow during call waiting. Referring to FIG. 3, first, in exchange 10, call waiting rejection service key 60 is registered at maintenance terminal 50 in telephone 1 in which the call waiting function is set.

Telephone (extension 1) 1 and telephone (extension 2) 2
During a call, the telephone (ext. 3) to the telephone (ext. 1)
When an incoming call is received at extension 1 (extension 3 originates at extension 1), the telephone (extension 1) 1 receives a call waiting tone (CWT) and a telephone (extension 3) by the call waiting function.
