Description

  The present invention relates to an inter-station pickup (inter-station proxy response) in a private branch exchange system provided with a plurality of switching devices.

  Until now, there has been no means for notifying other stations of incoming information for an incoming call group in a private branch exchange system, and information on the availability of proxy responses is registered inside the switching equipment, so information on other station terminals cannot be registered. In order to make a proxy response for incoming calls between different groups, it was always necessary to be within the same station. Therefore, in a private branch exchange system in which multiple switching devices are connected by a common line network, when relay stations or reception desks are operated at multiple sites, the situation of an overload at one site may be I couldn't pick up between stations from other bases.

  As a conventional technique for dealing with this type of problem, a pickup service is provided for a pickup group composed of an extension that has been adopted by a main private branch exchange and an extension accommodated in a secondary private branch exchange (for example, a patent) Document 1) and those that provide services such as pick-up, simple transfer, extension representative, and reset call between extension terminals that have been adopted by a plurality of exchanges are known (for example, see Patent Document 2).

  This is a proxy response method for terminals belonging to different groups within the same station, but allows the operator to freely select a proxy response for each incoming call, and display the incoming call with an individual name. A technique that facilitates smooth communication is also disclosed (see, for example, Patent Document 3).

Japanese Patent Laid-Open No. 6-70022 (page 3, FIG. 1) JP-A-4-281658 (3rd page, FIG. 1) Japanese Patent No. 2902724 (3rd page, FIG. 3)

  However, in the technique described in JP-A-6-70022, a proxy response is made between the extension registered in the pickup group registration table including the extension of the main private branch exchange and the extension of the secondary private branch exchange. There is a problem that the proxy response cannot be changed flexibly according to the usage status of the extension.

  In the technique described in Japanese Patent Laid-Open No. 4-281658, when the first exchange determines that the extension terminal that has received the call is not accommodated in its own exchange, the number of the extension terminal that has received the call is Since the switchboard is notified and the second switchboard makes a proxy response, the proxy response cannot be changed as needed.

  In the technology described in Japanese Patent No. 2902724, even if the operator performs a pickup operation, how long the incoming call has not been answered is the time since the operator noticed. There is a problem that the caller may have been waiting longer.

  An object of the present invention is to provide an inter-station pickup method capable of setting a pickup response flexibly.

  The inter-station pick-up method of the present invention is a private branch exchange system in which a plurality of switching devices are connected by a common line, and each switching device is connected to a plurality of relay stations / accepting stations for relaying or receiving incoming calls. In the inter-station pick-up method, the repeater / acceptor forms one or more groups for each switching device so as to be able to accept a group incoming call. The switching apparatus notifies all connected relay consoles / accepting stations and other switching apparatuses via the common line of the incoming information, and the other switching apparatuses connect to all connected relay consoles / accepting stations. The procedure for notifying incoming information and all the attendant consoles / reception desks analyze the received incoming information, and depending on the application settings, if it is an incoming call for the own group, the incoming call display process or the incoming call for other groups In other group incoming call processing and other group incoming call processing, if the unanswered state continues for a certain period of time, there is an unanswered call for another group incoming call, and if the other group incoming call display condition is met, the other group incoming call display And when there is a response from the repeater / acceptor based on the confirmation of the other group's incoming call indication, the procedure for sending response information from the switching device to the receiving switching device, and the exchange that received the response information The device responds to incoming calls from the trunk outside the station, sends the information on the call to all the attendant consoles / acceptors, and performs the procedure for canceling the incoming call on the attendant console / receiver receiving the information on the call. It is characterized by having.

  The other group incoming call display condition may be an unanswered time that is an elapsed time since the incoming call, or the number of stuck calls that have been received.

  In addition, the same group number and the same application relay stand / reception stand may be redundantly installed for different switching devices.

  In the present invention, when an incoming call occurs at a relay / accepting stand accommodated in a certain switching device in the network, the notification is also sent to other switching devices connected to this incoming information through a common line. Do. As a result, the relay board / reception board accommodated in the other exchange apparatus can recognize the incoming call accommodated in the other exchange apparatus. The repeater / reception stand accommodated in the other switching device recognizes this incoming call, and can pick up between stations even if it is an incoming call at the repeater / reception stand accommodated in its own station.

  Furthermore, according to the present invention, whether the incoming call to the outside trunk is an incoming call of the own group or an incoming call of another group is performed by the application of the relay / reception stand for separation.

  According to the present invention, it is possible to obtain the same effect as that of the prior art that it is possible to recognize and respond to an incoming call to the relay console / reception console at another station. In addition, according to the present invention, since the incoming call to the outside trunk is determined by the application of the attendant console / acceptor base whether the incoming call to the local group or the incoming call from the other group is performed, the pickup response can be set flexibly. It is possible to obtain a special effect that appropriate measures can be taken even when the attendant / reception stand is busy or down.

  Also, even in a redundant configuration in which the same group number and the same application relay stand / reception stand are installed for different switching devices, the same information is provided to these relay stand / reception stand via a common line. In addition, the effect of facilitating the determination of the group incoming can be obtained.

  The inter-station pick-up method of the present invention is a private branch exchange system in which a plurality of switching devices are connected by a common line, and each switching device is connected to a plurality of relay stations / accepting stations for relaying or receiving incoming calls. The present invention relates to an inter-station pickup method. The relay table / reception table forms one or more groups for each switching device so as to be able to receive group incoming calls. When there is a group incoming call from the off-station trunk, the switching device notifies the incoming switching information to all the switching devices / reception consoles connected and the other switching device via the common line. The other switching device notifies the incoming call information to all connected relay consoles / reception consoles. As a result, all relay consoles / reception consoles analyze the received incoming call information, and, depending on the application settings, perform incoming call display processing if it is a local group incoming call, and other group incoming call processing if it is an incoming call from another group.

  In the other group incoming call processing, if the unanswered state continues for a certain period of time, there is an unanswered call for an incoming call of another group, and the other group incoming call display is performed when the other group incoming call display condition is satisfied. Then, when there is a response from the relay / reception desk based on the confirmation of the other group incoming call display, response information is transmitted from the exchange to the exchange that received the call. The switching device that has received the response information performs a response process on the incoming call from the off-station trunk and transmits the busy information to all the relay / acceptance units. The relay console / reception console that has received the in-call information performs incoming call cancellation processing.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows an embodiment of an inter-station pickup system according to the present invention. This inter-station pickup system has a multiple switching network configuration, and has two switching devices A and B.

  The exchange device A is composed of out-of-office trunks a1 to a3, relay tables / accepting tables a4 to a7, and terminals a8 to a9. The relay table / reception table a4 and the relay table / reception table a5 form a group α1, and it is also possible to receive a group incoming call to the group α1. Similarly, the relay board / reception desk a6 and the relay board / reception desk a7 form a group α2, and it is also possible to receive a group incoming call to the group α2.

  The exchange B is composed of out-of-office trunks b1 to b3, relay / reception stands b4 to b7, and terminals b8 to b9. The relay consoles / accepting stations b4 to b7 form a group β, and can accept a group incoming call to the group β.

  The relay console / reception console refers to an operation console that relays or accepts incoming calls. Further, a group refers to a set of a plurality of relay tables / accepting tables that are appropriately grouped so as to be a group incoming target. Further, the off-station trunks a1 to a3 are external lines to the exchange apparatus A, and the terminals a1 and a2 are extension lines to the exchange apparatus A. The off-station trunks b1 to b3 are external lines to the switching apparatus B, and the terminals b1 and b2 are extension lines to the switching apparatus B.

  Exchange device A and exchange device B are connected by a common line c1. The common line c1 is also used for transmission / reception of a call information signal between the switching apparatus A and the switching apparatus B in addition to a call between the switching apparatus A and the switching apparatus B.

  Next, the operation of the present embodiment will be described in detail with reference to FIGS.

  Initially, it is assumed that there is an incoming call from the outside trunk a1 accommodated in the exchange A to the group α1 of the relay / acceptors a4 to a5 accommodated in the exchange A (2-1 in FIG. 2). . Then, the exchange apparatus A notifies the relay table / accepting tables a4 to a7 that there is an incoming call for the group α1, using the incoming call information 2-2.

  Further, the exchange apparatus A notifies the same incoming information 2-3 to the exchange apparatus B connected by the common line c1. Upon receiving this information, switching apparatus B starts signal reception processing (3-1 in FIG. 3), and notifies reception information 3-2 to relay boards / reception boards b 5 to b 7 accommodated in its own station.

  Each transmission information transmitted from the switching device is added with a caller-specified relay table / acceptor group number, and the switching device transmits each transmission information to all relay tables / accepting devices accommodated therein. It will be. The incoming call analysis of the own group / other group and the incoming call display of other group are performed by the application of the relay console / reception desk.

  The relay table / accepting tables a4 to a7 and b4 to b7 accommodated in each switching apparatus that has received the incoming information are activated by the incoming information analysis process (2-4 / 3-3). In the incoming information analysis process (FIG. 4), it is analyzed whether it is an incoming call of the own group (step 4-1 of FIG. 4), and in the case of an incoming call of the own group, an incoming call display process is started (4-2). The incoming call status is displayed on the relay / reception desk.

  On the other hand, if the incoming call is from other than the own group, the other group incoming process is executed (4-3). As a result, it is possible to distinguish between the incoming call of the own group and the incoming call of the other group according to the setting of the application of the relay board / reception desk, not the data by the exchange device.

  In the other group incoming call processing, when the unanswered state for the incoming call of the outside trunk a1 continues for a certain time, the relay / accepting stands a6 to a7 of the group α2 do not answer the outside trunk a1 receiving the group α1 incoming call. In the incoming call analysis process 2-5 and the relay / acceptors b5 to b7 of the group β, the unanswered incoming call analysis process 3-4 for the outside trunk a1 receiving the group α1 is started.

  In the unanswered incoming call analysis process (FIG. 5), it is checked whether there is an incoming call in an unanswered state (step 5-1 in FIG. 5). When there is an unanswered call for an incoming call of another group (group α1 in this example), the other group incoming call display condition is checked for the incoming call (5-2).

  The other group incoming call display conditions are unanswered time (elapsed time since the incoming call) or the number of stuck calls, and various conditions can be applied. When the other group incoming call display condition exceeds a set threshold value, other group incoming call processing is performed for the corresponding incoming call (5-3). In the other group incoming call processing, an incoming call display of “incoming call display (other group incoming call)” is performed. As a result, it is possible to confirm an incoming call to the group α1 also at the relay tables / reception tables a6 to a7 belonging to the group α2 or at the relay tables / reception tables b4 to b7 belonging to the group β.

  For example, when the operator of the relay board / reception board b5 confirms “incoming display (other group incoming call)” and performs the response process 3-5, the other station response process 3-6 is activated in the switching apparatus B, and is common. Response information 3-7 is transmitted to switching apparatus A via line c1. In the exchange apparatus A, when the response information 37 is received via the common line c1, the response processing 2-6 is activated, and it becomes possible to respond to the incoming call from the outside trunk a1. Further, since the state of the out-of-office trunk a1 has changed during the call from the incoming call due to the response process 2-6, the switching apparatus A notifies the relay table / accepting tables a4 to a7 of the busy information 2-7.

  In addition, similar in-call information 2-8 is notified to switching apparatus B connected via common line c1. In the exchange apparatus B that has received this information, the signal reception processing 3-8 is activated, and the in-call information 3-9 is notified to the relay / reception desks b5 to b7 accommodated in the own station.

  The relay / reception desks a4 to a7 that have received the in-call information are activated by the incoming call cancellation process 2-9, and the relay / reception desks b5 and b7 are activated by the incoming call cancellation process 3-10 to cancel the incoming call. The relay / reception desk determines that the corresponding incoming call is not already received, and performs processing such as deleting the incoming call display (4-10). As a result, all the relay consoles / reception consoles can confirm that the out-of-office trunk a1 is no longer receiving calls. In addition to being in a call, the same process flows even when the incoming outside-office trunk a1 abandons midway, and it can be confirmed that the incoming call is no longer being received.

  By such a series of operations, it becomes possible to pick up the intermediary pick-up (proxy response) for incoming calls from other groups.

  Next, the relay table / reception table of the group α1 is installed in the switching device B, and the same application as that in the group α1 of the switching device A is loaded on the relay table / reception table. A pickup system can be configured. With such a configuration, the group α1 can be backed up and coped with when the group α1 is busy or down. Also in this case, since both the relay stand / reception stand are connected by the common line c1 and the same information is provided, it is easy to determine the group incoming call.
