JPH02311064A - Extension representative connection system by no response - Google Patents

Abstract

PURPOSE:To surely connect a caller to an extension subscriber and to prevent undesired confusion between a reply party and the caller by transferring the call automatically to other extension subscribers in the extension representative group when the extension subscriber is called and the subscriber does not reply the call. CONSTITUTION:When a call comes to an incoming trunk 8 and am extension representative number for extension subscribers 1-3 is received, a central processing unit 5 accesses a storage device to read the information of the extension representative group thereby checking the idle state of the extension subscriber 1. When the extension subscriber 1 does not reply the call and a no response information time elapses by the time limit monitor of a timer 7, the central processing unit 5 checks the idle/busy state of the succeeding extension subscriber 2 and sends the call signal to the extension subscriber 2 when the extension subscriber 2 is idle to stop the transmission of the call signal to the extension subscriber 1.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an electronic exchange, and more specifically, to a plurality of extension subscribers, a representative extension number is set and one incoming call is predetermined. This invention relates to an extension representative connection method for connecting to an extension subscriber.

(Prior art) The conventional extension representative connection method calls an extension subscriber within the extension representative group, and if the extension subscriber does not respond, the incoming call is transferred to a forwarding destination registered in advance by the extension subscriber. It was equipped with a variable no-response transfer function.

(Problems to be Solved by the Invention) This variable call forwarding function has conventionally had the following problems.

(1) There is a possibility that the caller will be transferred to another department even though other extension subscribers in the extension representative group that the caller attempts to call are in the 9 state.

(2) Since the forwarding destination is not specified, if the forwarding destination is not contacted in advance, the responder will be confused about the response, and the caller will also be confused because the caller will be forwarded to an unexpected location.

(3) Since the extension subscriber must set the forwarding destination in advance, it will not function if the extension subscriber forgets to set it.

The object of the present invention is to overcome the above-mentioned drawbacks.

To provide an extension representative connection method due to non-response of an electronic exchange that can call other extension subscribers in the same extension representative group in turn if the first 71 subscribers in the extension representative group do not respond. It is in.

(Rounding Means for Solving the Problem) In order to achieve the above object, the extension representative connection system due to non-response according to the present invention includes an extension subscriber, one incoming trunk, one call path switch, a timer for setting a non-response identification time, This is an extension representative connection method due to non-response of a storage device, a central processing unit, and an electronic exchange included therein, and the storage device is connected to an extension representative 1? , the central processing unit accesses the storage device when there is an incoming call on the incoming trunk and the main extension number is received. , reads the extension subscriber information a corresponding to the extension representative number, sends a calling signal to the extension subscriber with the highest priority, and starts the timer for setting the non-response identification time, so that the non-response identification time has elapsed. However, if the extension subscriber with the highest priority does not respond, the extension subscriber corresponding to the representative extension number is read out, and the busy ft of the extension with the next priority is checked.

In the case of a call, the call signal is sent and the timer is restarted until the extension subscriber answers.

The system is configured to control calling extension subscribers in order.

(Example) The present invention will be explained in more detail below with reference to one drawing. Figure 1 is a relay system diagram showing an embodiment of an electronic exchange to which the non-response representative extension connection system according to the present invention is applied.

The storage device 6 stores extension subscribers 1. Information is stored in which the initials of extension subscriber 2ii- and extension subscriber 3 form one representative group of extension lines. Registration is performed by a known method.

When an incoming call is placed on the incoming trunk 8 and the representative extension numbers of extension subscriber 1, extension subscriber 2, and extension subscriber 3 are received, the central processing unit 5 accesses the storage device 6 and stores information on the representative extension group. is read out, and the empty/busy status t of the extension subscriber 1 to be selected first is checked, and if it is empty, a calling signal is sent to the extension subscriber l. At this time, the central processing unit N1.5 simultaneously sets the non-response identification time in the timer 7. Note that in this embodiment, extension subscriber 1 is selected by extension representative selection.
The operation is explained assuming that is selected.

The extension line was not answered and timer 7 monitored the time limit.
When the non-response identification time has elapsed, the central processing unit 5 accesses the storage device 6 and reads the information V& of the extension representative group to which the extension LA subscriber 1 belongs.

Extension subscriber 2 who should be selected as representative next to extension subscriber l
Check out the empty/talking state. If the extension subscriber 2 is in the idle state, the calling signal is sent to the extension subscriber 2, while the sending of the calling signal to the extension subscriber 1 is stopped.

If the internal m71O subscriber 2 is not in the idle state, the central processing unit 5 checks the idle/busy status of the next extension subscriber 3, and if the extension subscriber 3 is in the idle state, sends a paging signal to the extension subscriber 3. death,
Stops sending a paging signal to extension subscriber l.

Although the embodiment has been described above for the case where there is an incoming call to an extension representative group on the incoming trunk, all kinds of incoming calls to an extension representative group can be handled in the same way.

(Effects of the Invention) As described above, the present invention uses the extension representative connection function to call an extension subscriber in the extension representative group, and when a non-response is encountered, the call is automatically sent to other extension subscribers in the extension representative group. Since the caller is configured to transfer calls automatically, one caller may be transferred to another department even though the other extension subscribers in the extension representative group that the caller is trying to call are empty. Totally prevented.

The effect is that the calling party can be reliably connected to an extension subscriber within the extension representative group, and unnecessary confusion for the responder and the calling party can be prevented.
