Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay stand recall system for returning a relay stand in response to a request for an extension line.

In a switching center that receives a call received from the outside at a relay station and then transfers the call to a corresponding extension, when it is necessary to switch the call transfer destination, the transfer destination (extension) of the incoming call From the special number dial, the relay stand is called back.

[0003]

2. Description of the Related Art When an incoming call from an outside line is accepted by any of the relay stations, the operator holds the cord or releases the cord and transfers the incoming call to the extension.

When the extension of the relay stand recall is dialed at the extension which is the transfer destination of the incoming call, only the relay stand that transferred the call is recalled when the string is held, and all the relay stands when the string is released. Is called back.

Therefore, when the string is held, the operator who transferred the incoming call can be requested to switch the transfer destination, and when the string is released, the operator can immediately request the switching of the transfer destination even when the operator is busy or away from the desk.

However, since only the relay stand that transferred the call is called back when the cord is held, when the operator is busy or away from the desk, it is not possible to request switching of the transfer destination during that time.

For this reason, when the special number of the relay station recall is dialed by the extension which holds the cord and transfers the incoming call, when the relay station in charge does not respond even after a certain period of time (the operator (When busy or away)
Has proposed a method of automatically calling another relay stand in place of the relay stand (JP-A-55-068763).

[0008]

However, when the operator of the relay stand is busy or absent when the relay stand is called back when the cord is held, a certain period of time elapses. In the case of an urgent matter, it is impossible to process this immediately because the extension side has to wait until the relay stand is called.

If the operator who transferred the incoming call releases the string or the operator in charge of the string is busy or away from the desk, another operator who does not understand the circumstances at the time of the incoming call Since it is called, the operator cannot be expected to perform accurate processing.

When the call is put on hold, it is desired to wait for the call from the extension which is the transfer destination, so that the operator of the relay stand cannot leave the seat and is restrained by the relay stand.

The present invention has been made in view of the above conventional circumstances, and an object of the present invention is to provide a system of this type which enables more flexible call back of a relay stand.

[0012]

In order to achieve the above object, the relay stand recall system according to the first invention and the second invention is constructed as shown in FIG.

In the figure, the system according to the first aspect of the present invention connects the relay stand 10 and the extension 12 when a call received at any of the relay stands 10 and accepted is transferred to the extension 12. Relay information storage means 14 which is stored in association with each other
And when the first special number is dialed on the extension 12 to which the incoming call is transferred, the relay stand 10 for receiving the incoming call corresponding to the extension 12 is specified from the stored contents and called.
The call means 16 and the extension 12 to which the incoming call is transferred are second
When the special number of is dialed, all the relay stands 10
Second calling means 18 for calling.

In the system according to the second aspect of the present invention, when a call received at any of the relay stations 10 and accepted is transferred to the extension 12, the relay station 10 and the extension 12 are associated with each other. When the first special number is dialed by the relay information storage means 14 for storing and the extension 12 to which the incoming call is transferred, the relay stand 10 for receiving the incoming call corresponding to the extension 12 is specified from the stored contents. First calling means 1 for calling
6, a second calling means 18 for calling all the relay stations 10 when the second special number is dialed by the extension 12 to which the incoming call is transferred, and a third special number by any one of the relay stations 10. And a relay stand changing means 20 for connecting the relay stand 10 with the call of the first calling means 16 when dialed.
have.

[0015]

In the first and second aspects of the invention, when the first special number is dialed at the extension 12 which is the transfer destination of the incoming call, the relay stand 10 which has transferred the call is called back to the extension. Therefore, an operator of the relay stand who is familiar with the situation at the time of incoming call takes charge of the processing at this time.

When the second special number is dialed at the extension 12 which is the transfer destination of the incoming call, all the relay stations 10
Are called back, so that any attendant operator can be called immediately.

In the second invention, when the third special number is dialed by any one of the relay stands 10, the call back to the other relay stand 10 is switched to that for this relay stand 10.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of a relay stand recall system according to the present invention will be described below with reference to the drawings.

In FIG. 2, the exchange 22 includes a plurality of station line entrance / exit trunks 24, a network 26, a plurality of line circuits 28, a plurality of station line repeater controllers 30, and a central controller 3.
2. The main memory 34.

Further, each line circuit 28 has an extension telephone 3
6, a relay stand 38 is connected to each station line relay control device 30, and a call originated by an external telephone 40 is connected to any station line entrance / exit trunk 24, network 26, or any station line relay stand control device. An incoming call arrives at one of the relay stands 38 via 30.

When the operator of the relay stand 38 transfers the incoming call to any of the extension telephones 36 (step 300 in FIG. 3), the relay stand reception shown in FIG. The central control unit 32 accesses the call management table, and writes the station line number, extension number, relay station number, and string status to the table (FIG. 3_step 3
02).

Further, the central control unit 32 judges whether or not the operator has carried out a string holding operation (step 304 in FIG. 3). It connects to the telephone 36 (step 306 in FIG. 3), and the network 26 is released when the string is released.
The telephone 40 and the corresponding extension telephone 36 are connected via (step 308 in FIG. 3).

Then, when the extension number 36 of the call transfer destination dials the special number of the relay stand recall for returning only the relay stand 38 of the call transfer origin (FIG. 5_step 500), the central control unit 32 of FIG. The relay stand reception call management table is accessed (FIG. 5_step 502), and it is determined whether or not the call is a call with the line held (FIG. 5_step 504).

At this time, when it is confirmed that the call is a cord-holding call, the central control unit 32 calls the relay stand 38 (operator) to which the call has arrived via the central line relay stand control unit 30 (FIG. 5_step). 506), when it is confirmed that the call is a string release call, the call is made via the network 26 (step 508 in FIG. 5).

When the extension telephone number 36 of the call transfer destination dials the special number for the relay stand recall to call back all of the relay stand 38 (step 600 in FIG. 6), the call back is performed via the network 26. (FIG. 6_step 602).

Further, in accordance with the procedure of FIG.
When 8 is called back and the operator is busy or away from the desk, the operator in charge of the other relay stand 38 inputs a predetermined special number to the own relay stand 38 (Fig. 7_step 700).

When the input of this special number is confirmed, the central control unit 32 accesses the relay stand reception call management table of FIG. 4 (FIG. 7_step 702), and if the call is a call with the cord held, the extension of the call back source is called. Relay station 3 for telephone 36 with special number input
8 and the call-back destination relay stand 38 are connected instead of via the station line repeater stand control device 30 (steps 704 and 70 in FIG. 7).
6). If the call is for releasing the string, the network 26
To connect via (step 708, 71 in FIG. 7).
0).

If the central control unit 32 confirms the special number input requesting this call back even though the call back targeting only one of the relay stands 38 has not been made, the special number is input. The operator (relay stand 38) who has input is notified of an operation error in the special number input (step 712 in FIG. 7).

As described above, according to the present embodiment, the extension, which is the transfer destination of the incoming call, calls back the relay stand 38, which is the transfer source of the call, and the relay that is detailed in the situation of the incoming call. It is possible for the operator of the table 38 to be in charge of the processing at this time, and therefore, the operator can be expected to perform accurate processing.

In the case of an urgent matter, since the operator of all the relay stations 38 can be called back from the extension which is the transfer destination of the incoming call, the operator who responds first can immediately handle the matter. It will be possible.

Moreover, the relay stand 3 from which the incoming call is transferred
The call back of No. 8 and the call back of all the relay stands 38 can be arbitrarily selected from the extension which is the transfer destination of the incoming call regardless of whether the call is held or released. The switching center can be operated more efficiently by properly using or combining them.

The operator of each relay station 38 can receive this call and perform processing on behalf of the other relay station 38 when it is being called back. Therefore, the operator of the relay station 38 that holds the incoming call is held. Can leave the seat if necessary, and is therefore not bound by the relay stand 38.

[0033]

As described above, according to the present invention, the calling of only the relay station which transferred the incoming call and the call back of all the relay stations are arbitrarily selected on the extension side which is the transfer destination of the incoming call. Therefore, it is possible to operate the system more efficiently by causing the relay station operator at the recall destination to appropriately or promptly perform the processing.
