However, there is a problem that when the call charges are processed in the sales company, it is not possible to bear the burden on an appropriate department or person in charge.

[0004] This prior art is applicable to a single telephone apparatus and a key telephone apparatus that have received a call. When a proxy response is made by using the terminal of (1), there is a problem that the terminal of the other department that has responded is charged and the department that should be charged is not charged.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a local line call billing system based on calling telephone number notification, which can always charge an appropriate department or individual. .

[0006]

The invention according to claim 1 is a billing system for an incoming line telephone call, which comprises means for receiving an outgoing telephone number sent from an office line, It has a calculating means for calculating a call charge, an input means for inputting an identification number designating a chargeable person, and a storage means for storing a total call charge for each chargeable person using the identification number as an index. I do.

According to a second aspect of the present invention, there is provided a billing system for an incoming call on a local line, wherein an index assigned to the storage means is individual.

According to a third aspect of the present invention, there is provided a billing system for incoming line telephone calls, wherein the index assigned to the storage means is classified by department.

According to the first aspect of the present invention, the call charge calculated by the calculation means is charged to the storage means provided with an index corresponding to the identification number designated by the input means. The target person can be charged.

[0010] According to the second aspect of the present invention, since the index assigned to the storage means is individual, it is possible to select and charge a person to be charged for each individual.

According to the third aspect of the present invention, since the indexes assigned to the storage means are classified by section, it is possible to select and charge a person to be charged for each section.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a block diagram showing a system configuration according to an embodiment of the present invention.
A) Caller telephone number receiving register (RST) that receives 1 and the caller telephone number and the extension number of the connection destination received from the station.
2 and office line trunk (COT) that performs connection processing with office lines
3 and a call path switch (SW) for switching connection of the call path
4 and a processor (CP) for controlling the entire system.
U) 5).

The processor 5 includes one table and four memories A to D as shown in FIG. Table 1 stores the unit number of call seconds and the unit charge for each distance section using the distance section as an index. Here, the unit talk seconds indicates the number of seconds that can be talked at a unit talk charge (for example, 10 yen). The unit call charge indicates a charge unit for the call time.

In the memory A, the station number of the private branch exchange is stored in advance as the installation position information of the private branch exchange. The memory B stores the caller telephone number received from the office line. The memory C is provided for each central office trunk 3, and is divided into a unit call second storage area, a unit call charge storage area, a call charge storage area, and a department / personal number storage area. The unit call second storage area and the unit call charge storage area store the unit call second and the unit call charge selected from Table 1, respectively. The call charge storage area stores the total call charge required for one call. The department / individual number storage area stores the department / personal information entered by operating the extension telephone.
The personal number is stored. The department / individual number is assigned in advance to each department or individual by a symbol such as an alphanumeric character. The memory D stores accumulated call charges for each department / individual, using the department / individual number as an index.

Next, the operation of one embodiment of the present invention will be described with reference to the drawings. When an incoming call from the office line is detected in the office line trunk 3, the processor 5 selects an empty outgoing telephone number reception register 2 and controls the communication path switch 4 to control the office line trunk 3 and the outgoing telephone number reception register. 2
And connect. And the outgoing telephone number reception register 2
Receives the outgoing telephone number and connection destination extension number notified from the office line.

Then, the processor 5 stores the outgoing telephone number and the connected extension number received by the outgoing telephone number receiving register 2 in the memory B corresponding to the office trunk 3 where the incoming call is detected, and stores the outgoing telephone number. The extension telephone 1 is called based on the information. When the extension telephone 1 answers this call, the billing calculation data (unit call seconds,
Unit call charge).

First, the distance between the private branch exchange and the caller is calculated from the station number indicating the installation position of the private branch exchange registered in the memory A in advance and the area code of the calling telephone number stored in the memory B. To determine the distance division. The unit call seconds and the unit call fee are determined by referring to Table 1 from the distance division. The unit call seconds and unit call charges are:
The incoming call is stored in the memory C corresponding to the central office trunk 3 that has detected the incoming call.

Thereafter, while the extension telephone 1 and the central office trunk 3 are talking, the memory C is constantly monitored, and each time the unit call seconds elapse, the unit call is reduced to the call charge stored in the call charge storage area. Add the fee.

The extension person who responds to the incoming call determines the department / individual most suitable for assigning the call fee from the contents of the call with the caller, and operates the number keys of the extension telephone 1 to input the department / individual number. I do. The entered department / personal number is stored in the department / personal number storage area of the memory C.

When the call ends, the trunk trunk 3 is restored in response to a restoration request from an extension. At this time, the contents of the memory C corresponding to the line trunk 3 are confirmed. Memory C
