Abstract

PURPOSE:To attain talking with an extension desired by a caller by applying camp-on registration to an incombing call to other busy extension. CONSTITUTION:A subscriber 1 is connected to a register 7 by dialing ''1'' in order to transfer an incoming call to a subscriber 2 upon request of a subscriber 6. When subscribers 2 and 3 are talking via an intra-office trunk IOT8 and the register 7 receives busy information of the subscriber 2 from a CPU9, a busy tone is transmitted to the subscriber 1. The subscriber 1 receiving it dials a special number to apply camp-on registration of the subscriber 6 to the subscriber 2 via an incoming trunk ICT5. The CPU9 identifies the allocated location of the ICT5 after the reception of the special number and the number of the subscriber 2 and attains camp-on connection with the subscriber 2. After the end of talking of the subscriber 2, when the subscriber 2 hooks on a handset, the ICT5 detects it, transmits a call tone to the subscribers 2, 6, and when the subscriber 2 responds to it, the talking is started.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a transfer connection system for incoming calls in a private branch exchange.

(Tr (“Next technology”) Conventionally, when an extension housed in a private branch exchange answers an incoming call and transfers the incoming call to another subscriber, if the called subscriber to whom the call is transferred is busy, the call is interrupted. After hearing the tones, the answering subscriber must perform a re-operation to respond to the caller again and notify the caller that the called party is busy, resulting in a complicated operation, a loss of one hour, and a disadvantage in terms of service.

(Object of the Invention) The object of the present invention is that when a subscriber who has answered an incoming call transfers the incoming call to another subscriber, if the called subscriber to whom the call is transferred is busy, the call can be canceled by the operation of the answering subscriber. The object of the present invention is to provide a transfer connection method that solves the above drawbacks by enabling on-registration.

(Summary of the Invention) According to the present invention, when a subscriber who has answered an incoming call in a private branch exchange transfers the incoming call to another subscriber, when the called subscriber to whom the call is transferred is busy, the responding subscriber operates the Thus, an incoming call transfer connection system is obtained which is characterized by having means for camp-on connection.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a relay system diagram of an embodiment of the present invention, in which a subscriber (B
) 2 and (C) 3 are in a call via IOT 8, and subscriber (A) l is communicating with external subscriber (D) 6 via ICT 5.
I'm on a call.

Subscriber Figure 1 is subscriber (B) 2 at the request of subscriber) 6.
In order to transfer the incoming call to the subscriber (B) 2, the subscriber number ``xxxx'' of the called subscriber (B) 2 connected to the register R7 is dialed by l-dial or hook-up. At this time, subscriber (D) 6 is placed on hold at ICT 5.・
...Route ■ After receiving the subscriber number of the called subscriber (B) 2, the register R7 transfers the received information to the CPU 9.・・・・・・
Route ■ The CPU 9 checks the status of the subscriber (B) 2 based on the received information.・・・・・・Root 0th CPU
9 transfers this busy information to register R7 since the called party 2 is busy. ...Route ■ Register R7 receives busy information from CPU 9 and sends a busy tone to subscriber (5)l.・・・・・・Route ■ After confirming the busy tone, subscriber (A) 1 sends special number 1 = Dial...
After receiving the special number "x", the root register R7 starts up the CPU 9't again and transfers the special number "x" and the previously received and stored information of the called subscriber .beta.)2.・・・・・・Route■ CPU 9 receives the special number “X” and the called subscriber (B12
After receiving the number, the location of the ICT5 is identified and the subscriber (B
)2 and set the cap-on connection. ...Route■ At this time, the CPU 9 sends camp-on completion information to the ICT 5.

Next, after receiving the camp-on completion information from the CPU 9, the ICT 5 sends a camp-off sound to the subscriber (B) 2 and the subscriber (D) 6, and the camp-on is registered.
Let them know that they are being mediated. ...Route ■ After the subscriber g3)2 hangs up the handset, the iICT5 detects this and sends a calling signal to the subscriber (B)2.

A ring tone is sent to subscriber (D) 6. Subscriber (B)
When 2 answers, the call is immediately started.

Incidentally, cap-on connections between extension subscribers and when an incoming call to a central office line is made are also performed by the same means as described above.

(Effects of the Invention) As explained above, the present invention allows the caller to make a call to the desired extension without having to make a re-dialing by registering the incoming call as a camp-on to the extension that is currently busy. It has the effect of allowing you to do this.
