Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange device and a call transfer method for use in a telephone exchange system for transferring a call.

[0002]

2. Description of the Related Art Conventionally, a call being made by one extension telephone may be transferred to another extension telephone. The following method is known as such transfer to an extension telephone.
In addition, there are the following proposals similar to this. (1) Perform a predetermined call transfer operation. (2) The call to be transferred is set to hold, and the extension call to be transferred responds to the hold call. (3) A "button telephone device" disclosed in Japanese Patent Laid-Open No. 61-103391 is proposed. This "button telephone device"
Then, press the "Individual button Extension call button" during a call with an outside line, and this will call the called phone,
A flashing display peculiar to transfer is displayed on the station line lamp. (4) A "button telephone device" disclosed in Japanese Patent Laid-Open No. 63-103594 is proposed. This "button telephone device"
Then, the telephone is provided with a transfer button for setting a plurality of transfer destinations, and the coded name of the other party is associated with the transfer button and registered. Then, one of the buttons is pressed during an outside line call, the name of the transfer destination is displayed in kana characters on the LCD display portion of the telephone corresponding to this pressing, and the call is made at the same time.

[0003]

The above-mentioned conventional examples (1) to (4) have the following drawbacks. The transfer method (1) involves button operation for a relatively long time. Further, it is necessary to be familiar with the extension number of the transfer partner. In addition, since the operating method differs depending on the model, it is difficult to learn the operating method. In the method by the hold of (2), only a relatively conspicuous button is pressed, and it is simple, but when answering a held call, one outside line is provided with a pair of LEDs and buttons. At this time, in the hold state of the outside line, the color of the corresponding LED changes so as to display the hold, and the LED is turned on and blinked. Then, off-hook and press the corresponding button to respond to the held call. However, in this method, it is necessary to learn correspondence between various states of a call and blinking patterns of LEDs. Further, in the method using the hold call pickup function, the special number for answering the hold call must be put in off hook. In this case, if there are a plurality of held calls, it is not easy to select a desired call. In the "button telephone device" of (3), it is necessary to be familiar with the extension number of the transfer destination when designating the transfer destination. Furthermore, it is hard to remember because the display method of the transfer destination is blinking of the lamp. In the "button telephone device" of (4), since one button is assigned to one destination, it is difficult to arrange a desired number of buttons in a limited telephone area.

The call transfer operation as described above is generally troublesome, although it varies depending on the person. SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a telephone exchange and a call transfer method that facilitates call transfer operation.
