Abstract

PURPOSE:To offer the better service to a station-side caller by detecting an incoming wait tone to the 1st extension of individual incoming registration when a individual cal comes during talking so as to respond to the said station incoming within a predetermined time. CONSTITUTION:The 1st EXT.1 listens to the incoming wait tone, informs that the station incoming to an opposite party during talking within a prescribed time (e.g., 10sec) and applies response specific number (e.g., hooking and specific number) without hooking on for the response to the station incoming call such as end of call or temporary retention as shown in a known technology. A time collation circuit TCMP uses the special number, collates a retistered time in the MM and gives connection command between the 1st extension EXT.1 and the said trunk line to attain the talking with the trunk line. Moreover, when no response dial comes from the 1st extension EXT.1 even when a prescribed time is elapsed, a slide incoming control is attained according to the predetermined priority in the path shown in figures 2, 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an individual call termination system, and particularly relates to busy processing when an extension individual call is received in a distributed response system.

[Background of the invention]

In recent years, as part of a distributed system, when a call is received from a central office line, it has been considered to connect directly to an extension line registered to support the central office line, that is, to perform an individual call receiving system. In this method, when the first extension registered as a central office line and the first internal line are busy or there is no response, the second extension is used as the answering agent. You can register the third extension. In addition, if all the registered extensions are busy or unanswered, there is a central office line display board for displaying incoming calls, and if the display board displays an incoming call, a well-known dispersion method is used to communicate with the central office line. Distributed responses can be made from general extension lines that are allowed to make calls.

With this system, when a call arrives on a central office line, if the first extension registered for central office line support is busy, the second extension is immediately called, according to the preset priority order. The display on the 3rd extension or central office line display panel slips and a third party answers, so the caller on the central office side wants to make an urgent call directly to the registered extension @1 that corresponds to the central office line, but the third party has the disadvantage of forcing you to make unnecessary calls.

[Purpose of the invention]

An object of the present invention is to eliminate the above-mentioned conventional drawbacks, and when a call is received from the central office line while the first extension registered as compatible with the central office line is in the middle of a call, a special tone is sent to the called party and the call is received. It is desirable to provide an individual call termination system that notifies the user of the incoming call and allows the user to respond to the incoming call.

[Summary of the invention]

According to the present invention, when a first extension registered as compatible with a local office line receives a call from the central office line while the first extension is on a call, a waiting tone for an incoming call is heard only on the first extension, and if there is a response within a certain period of time based on time monitoring, Pressure is applied to answer the call on the central office line, and if there is no response within the specified time and the caller on the central office side does not recover, the call is displayed on the second extension or on the central office line display board, etc. It is.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

The dotted lines in FIGS. 1 and 2 indicate the conventional flow, and all parts related to the present invention are shown in thick lines. In the figure, NW is the network, COT is the trunk for individual incoming office lines, CWT is the standby tone generator for incoming office lines, CPU is the central processing unit, MM is the main memory, T and P are the office line display panels, and TCMP is the central processing unit. In the time matching circuit, EXT, 1 is a first extension subscriber, E XT, 2 is a second extension subscriber, and E XT is a general extension subscriber.

When an incoming call is received from the central office line, the route shown in Figure 1 (■) is used to check the empty or busy state of No. 1 @E However, if the first extension E 1 extension EXT, 1 is connected to announce the incoming call from the central office line, and the CPU also connects to the main memory M
The connection time of the standby sound generator CWT is registered and the elapsed time after the generator is connected is clocked in a time monitoring area provided by the MK. On the other hand, according to instructions from the CPU, the time verification circuit TCMP receives the information in the MM time monitoring area and the presence or absence of a response from the office line from the first extensions EXT and 1 via the CPU, and performs a moment-by-moment verification. .

No. 1 @ B As in the known technology, a response special number (for example, hooking + special number) is performed without hooking on to a person who answers an incoming call.

The time verification circuit TCMP uses this % number to check the registered time in MM, and if it is within a certain period of time, the first extension EXT,
1 and the relevant office line, and can make a call with the office line. In addition, even if a certain period of time has passed during verification, the first and ninth
i1EXT, if there is no answer dial from 1,
Slide incoming control to the second extension EXT, 2 or the central office line display panel LP is performed according to the predetermined priority order using the routes shown in FIGS.

In this embodiment, storage of the time monitoring function such as time registration when connected to the incoming call standby tone generating device in the memory area of the main storage device MM and installation of the time verification circuit TCMP are limited to the device. The present invention also includes storing and controlling the function in another device.

〔Effect of the invention〕

As described above, according to the present invention, when there is an incoming individual call during a call, an incoming call standby tone is sent to the first extension registered for individual incoming calls, so that the incoming call can be answered within a predetermined time. , Also, if the caller on the station side does not recover after a certain period of time,
Individual incoming call registration By sliding the incoming call on the display on the first extension stone or the central office line display panel, it is possible to provide better service to the caller on the central office side.
