Abstract

PURPOSE:To call a desired opponent even when a user is separated from its own seat by registering a moving destination to a storage in case the user is separated from its own seat when the user of an extension telephone set executes the registering operation of extension camp-on. CONSTITUTION:When dial information received by an ORT 5 are inputted, a CC 8 recovers the ORT 5 and registers specified information, which are that a transmitting side is A, a terminating call side is B and the moving destination is C, to an MEM 9. When the telephone number of the C is not inputted, the CC 8 executes the processing of the normal extension camp-on. Then, when the telephone number of the C is inputted and the call end of the B is detected by an LC.b2, the CC 8 refers the specified information of the MEM 9 and connects an RT 7 to an LC a1. Then, the A is called. When the A does not respond during a determined time, the CC 8 refers the specified information of the MM 9 and connects the RT 7 to an LC.c3 and C is called.

Description

DETAILED DESCRIPTION OF THE INVENTION G) Field of Industrial Application The present invention relates to an extension camp-on transfer method in a private branch exchange equipped with an extension camp-on function.

Naka) Conventional technology The conventional extension Gandeon system will be explained below.

When the first extension telephone desires to connect with the second extension telephone and the first extension telephone performs the connection operation, and the second extension telephone is busy, the first extension telephone A busy tone is sent. Here, extension camp-on is set by performing a predetermined operation on the first extension telephone. If extension camp-on is set, the first extension telephone is called when the second extension telephone becomes idle.

When the first extension telephone answers, the second extension telephone is called. Here, when the second extension telephone answers, a call between the first extension telephone and the second extension telephone is started.

The extension camp-on method described above includes a method that allows extension camp-on operation even for the second extension telephone set in the extension representative group (Japanese Patent Application Laid-open No. 1981-191156), or A device that calls back the first extension telephone from the second extension telephone that is not
No. 059) has been proposed.

(c) Problems to be Solved by the Invention In the above-mentioned nine conventional methods, the user of the first extension α filling machine who is the registrant of extension camp-on has to leave his/her own seat after setting extension camp-on. The problem is that you can't leave.

The present invention was conceived in view of the above-mentioned circumstances, and it is an object of the present invention to provide an extension camp-on transfer method that allows a user to leave his/her seat even after setting an extension camp-on.

←) Means for Solving the Problems The present invention provides that when extension camp-on is set from a first extension telephone to a second extension telephone, the second
In the extension camp-on method of a private branch exchange that calls the first extension telephone when the extension telephone becomes idle, when setting the extension camp-on, the third extension telephone?
If a third extension telephone is registered in the storage device and there is no response even if the first extension telephone is called for a predetermined period of time, the third extension telephone is registered in the sixth extension number 1. This is an extension camp-on transfer method that requires calling.

(E) Effect According to Fan Ming, when the user of the first extension telephone registers the extension camp-on, he remembers the destination (the third extension telephone) when he leaves his desk. By registering with the device, you can talk to a desired party at your destination even when you are away from your desk.

(F) Examples Hereinafter, the present invention will be described in detail based on drawings showing examples thereof.

FIG. 1 is a block diagram of a PBX to which the extension camp-on transfer method according to the present invention is applied.

In the figure, (4) is a PBX network, including line circuits (LC-a)ill, (LC-b)+21,
(LC'l') 171 books are connected.

Further, connected to the network (4) are a central control unit 1t (CC)+81 as a control center, and a storage device (MEM)+91 used for control by this CC (81).

Furthermore, LC-all has an extension phone prisoner, and LC-b
Extension telephone (2) is connected to extension telephone (2), and extension telephone 0 is connected to LC-cf31.

Next, based on the flowchart showing the control method of the CCf81 shown in FIG. 2, the operation in the case where A is the calling side, B is the called side, and C is the destination will be described.

C (j81 sends A's call (off-hook) to LC-all
When detected by , LC-all is ORT +51
Connect to. Next, CCf81 is AyoshiORT (5
Enter the dial information (B's same line number) received by No. 1.

CC (81) compares the dial information with B's dial information stored in MEM+91 and detects that the call is from one person to B.

At this time, if B is busy, CC (81 is LC/b)
(2) detects that B is busy, so it restores ORT (51) and sends B T to LC-all.
Connect +61 and send a busy tone to someone.

CC (81, in this state, hooks A to LC-a
When detected by
5), disconnect A and BTf61, and connect A
Stop sending busy tone to.

Next, CCf81 inputs the dialing information received by A1 (special number indicating extension camp-on registration and C's telephone number) from A, and restores ORT (5+), and the calling party Register specific information that the destination of B1 is C in M B M +91 (
Step 81). If you do not enter C's phone number, CC (81) will perform the normal extension camp-on process, and if you enter C's phone number, then transfer the extension camp-on as described below. .

When CC (81) detects the end of B by Lc-bf21 (step S2), it refers to the specific information of MBMf91, connects RTI71 to LC-all, and connects A
is called (step 85).

Here, the person is called for a predetermined time (the number of calls)
If there is no response within (step S4).

CC (81 refers to the specific information of MEM+91, connects RT+71 to LC-c (31), and calls C (step call (step 87)).

When CC[s+ detects B's response by LC-bf2+ (step 8B), it connects B and C and erases the specific information (step 89).

(g) Effects of the Invention As is clear from the above description, the present invention provides a caller, that is, a caller who registers an extension camp-on and temporarily leaves his or her desk (away from the registered first extension telephone). The user can also talk to a desired party (second extension telephone) at the destination (sixth extension telephone).
