Description

[Detailed Description of the Invention] [Summary] Regarding a call type proxy response method in a private branch exchange equipped with a proxy response function, the present invention aims to enable a proxy answerer to respond to an incoming call of a desired call type by proxy. call type priority registering means for registering in advance the priority of the proxy response corresponding to the call type; call type priority proxy response means for responding preferentially to an incoming call of a given call type, and call type designation registration means for pre-registering designation information for designating the call type at the time of proxy response; call type designated proxy response means that refers to the call type designated registration means and responds to an incoming call with a call type corresponding to the specified designated information when the extension executes a predetermined proxy response operation specifying designated information; The system is configured to provide the following.

[Industrial Application Field] The present invention relates to a call type proxy response system in a private branch exchange equipped with a proxy response function.

As one of the increasingly diversified functions of private branch exchanges, a proxy answering function (-name pick-up function) is in use, in which a call received at an absent extension is answered from another extension within a predetermined range.

[Conventional Technique ((i)) FIG. 6 is a diagram showing an example of a conventional private branch exchange, and FIG. 7 is a diagram showing an example of proxy response processing in FIG. 6.

In FIGS. 6 and 7, extensions 2□, 26.26.2. and 28 form a proxy response group G that executes a proxy response function, the main memory (MM) 13 stores each extension 212, . 2c, 2. and 28 extension number DN.

, DNb, DN-, DNa, and DN are registered in the proxy response group table 131, which is provided in advance by a proxy response group registration operation executed from the maintenance console 17, for example.

In this state, a call is received from the office line 3 to two extensions, and a call is received from the trunk line 4 to extensions 2. When a call is received from extension 2f and a call is received from extension 2c, the central controller (CC) 12 calls each extension 2. ．． 2. and a subscriber circuit (LC
)14. ．． 14b and 14c, and sends an intermittent calling signal to each extension 2□, 2. and 2c, and the calling extension numbers DN1, DN, and DN in the proxy response group table 131 provided in the main memory (MM) 13.
The call origination information is set corresponding to c.

At this time, extension 2. ．． 2. and 2c are both absent, extension 2. ．． 2. When the other extension 28 notices the incoming call to 2c and makes a proxy answer, it performs a predetermined operation, for example, after lifting the handset, operates the proxy answer key provided on the telephone of extension 2P. , central control unit (
CC) 12 is a subscriber circuit (LC) 14. When it detects a call from the extension 28 via the system and identifies that a proxy response operation has been executed, the proxy response unit 121 is activated.

The activated proxy response unit 121 is connected to the main memory (MM) 1.
3, refer to the subscriber data 1328 provided corresponding to the extension 28 that executed the proxy response operation, and
identifies the proxy response group G2 to which it belongs (step 511 in FIG. 7).

Next, the proxy response unit 121 refers to the proxy response group table 131 provided in the main memory (MM) 13 corresponding to the proxy response group Gp, and sets the registered extension numbers DN-, DN.
b , DNc1, DNa, and DN, extension numbers DN, , DN, and D for which call birth information t is set
Nc is searched in a predetermined order, for example, in reverse order starting from the extension number DN of the extension 2e that executed the proxy response operation, in the order of extension numbers DNd, DNCXDN, and DN3 in FIG. 6 (step 512).

As a result of the above search, when it is first detected that the incoming call information is set in the extension number DNc, the proxy response unit 12
1 receives an incoming call to extension 2c from extension 2, which performed the proxy response.
8 for incoming connection (step 513).

As a result of the above, extension 2゜, which attempted to receive a call to extension 2゜,
A proxy response will be made by another extension 2° belonging to the proxy response group Gp.

However, extensions 21 and 2. Since no proxy response is performed for an incoming call to , the caller on the central office line 3 and trunk line 4 continues to wait for the called party to respond.

[Problem to be Solved by the Invention] As is clear from the above explanation, in a conventional private branch exchange, a plurality of extensions 2□, 2. and 20, when extension 2° executes the proxy response operation, the proxy response process is executed for the detected extension 2c according to a predetermined order.
However, rather than extension 2c, which received a call from an extension, the number of calls received from extension 2□, which received a call from a central office line, or from a trunk line! 2. Even if you wish to be answered preferentially, the desired extension 21 or 2.
It was impossible to respond on behalf of the company, and there was a problem with poor service quality.

SUMMARY OF THE INVENTION An object of the present invention is to enable a proxy answerer to respond to an incoming call of a desired call type.

In FIG. 2, a call type priority table 133 is provided in the main memory (MM) 13 as the call type priority registration means 100 in FIG.
A call type priority proxy response unit 122 is provided in the central controller (CC) 12 as the call type priority proxy response unit 200 in a).

Further, in FIG. 4, a proxy response possibility table 134 is provided in the main memory (MM) 13 as the call type designation registration means 300 in FIG. 1(b), and the A call type special number proxy response section 123 is provided in the central controller (CC) 12 as a type designated proxy response means 400 .

Also in FIG. 2, extensions 2.
．． 2. ．． 2c, 2. and 28 constitute a proxy response group Gp that executes a proxy response function.

Extension 28 is for the call type of the incoming call to be answered by proxy,
Incoming calls from extensions are given first priority, calls from central office lines are given second priority, calls from trunk lines are given third priority, and extension 2 is given priority.
．． gives first priority to incoming calls from trunk lines, second priority to incoming calls from extension lines, third priority to famous calls from central office lines, and gives first priority to incoming calls from central office lines for extension 2o. Incoming calls from trunk lines are given second priority, incoming calls from extensions are given 3rd/Z priority,
Also, extension 2d is inside! ! Incoming calls from the office line are given first priority, calls from the central office line are given second priority, calls from extensions are given third priority, and extension 28 gives incoming calls from the central office line first priority, and calls from the extension are given first priority. When incoming calls are given second priority and incoming calls from trunk lines are given third priority, and a predetermined proxy response group and call type priority are registered from the maintenance console 17, the main memory (MM) 13 stores data. , each extension 2□26.2c, 2. belonging to proxy response group G2. and 28 extension number DN.

, DN, , DNc1, DN, and DN, and each extension number DN, , DN, , DNc, DN, and DN8.
and priority information P1 indicating the first priority, second priority A call type priority table 133 is provided in advance, in which priority information P2 indicating the third priority and priority information P3 indicating the third priority are registered.

In this state, from the central office line 3 to extension 2. A call arrives at
A call arrives from line 4 to extension 2b, and then to extension 2. When a call arrives at extension 2c from 21.2c, central controller (CC) 12, as described above, connects subscriber circuits (LC) 14, . 14. and 146, and sends an intermittent calling signal to each extension 2-12b and 2o that can identify incoming central line calls, medium line calls, and extension calls. The extension number DN! in the call type priority table 133 Call origination information L3 indicating an incoming call from a central office line corresponds to , call origination information t4 indicating an incoming call from a trunk line corresponds to an extension number DN, and call origination information t4 indicating an incoming call from an extension line corresponds to an extension number DNc. Call origination information L2 indicating an incoming call is set respectively.

At this time, if extensions 2□, 2b and 2e are all absent, extensions 2□, 2. Then, in order for the other extension 28 who has noticed the incoming call to 2c to answer on behalf of the user, a predetermined operation is performed, for example, after lifting the handset, the other extension 28 operates the proxy answering key provided on the telephone of extension 2°. Then, the central controller (
CC) 12 is a subscriber circuit (LC) 14. When it detects a call from the extension 28 via the system and identifies that a proxy response operation has been executed, the call type priority proxy response unit 122 is activated.

The activated call type priority proxy response unit 122 stores in the main memory (MM) 13 the extension 2. The proxy response group Gp to which the extension 2e belongs is identified by referring to the subscriber data 1328 provided corresponding to the third
Figure step 521).

Next, the call type priority proxy response unit 122 stores the main memory (M
M) 13, refer to the call type priority order table 133 provided corresponding to the proxy response group Gp, and select the extension 2. Corresponding to the extension number DN of
z, it is identified that third priority information p3 is registered for the incoming call type C4 from the trunk line (step 522).

Next, the call type priority proxy response unit 122 refers to the call type priority table 133 and performs proxy response operations corresponding to the extension numbers DN1, DN, DNc, DN4, and DN registered in the proxy response group Gp. Search for the extension number DN for which the call origination information t3 is set, indicating that the extension 2゜ that executed the above call has received a call from the central office line for which the first priority information p is registered (
Step 523).

As a result of the search, call birth information t, corresponding to extension number DN,
is set (step 524)
The call type priority proxy response unit 122 connects the incoming call from the office line 3 to the extension 2a to the extension 28 that has executed the proxy response (step 525).

As a result of the above, the office line 3 attempting to receive a call to the extension 21 will be responded to by proxy from other extensions 2.4 belonging to the same proxy response group G2.

Note that after extension 28 finishes proxy answering for the incoming call from central office line 3 to extension 21, if extensions 2° and 2c are still ringing and extension 28 performs the proxy answering operation again, the central control The device (CC) 12 activates the call type priority proxy response unit 122 in the same process as described above, and the activated call type priority proxy response unit 122 refers to the call type priority table 133 in the same process as described above. Extension numbers DN1, DNb, DNc, DNd, and DN8 registered in proxy response group G
Among these, an extension number DN is searched for which call origination information t3 indicating an incoming call from a central office line for which extension 28 has registered first priority information p is set (step 523).

As a result of the search, the incoming call from office line 3 to extension 2□ has been answered, and the call origination information t that was set corresponding to extension number DN has also been cancelled, so the call origination information t3
If the extension number DN for which the 28 searches for an extension number DN in which call origination information L2 indicating an incoming call from an extension for which second priority information p2 is registered is set (step 526).

As a result of the search, call birth information t2 corresponding to extension number DNC
is set (step 324)
, the call type priority proxy response unit 122 connects extensions 2f to 2o.
The incoming call to extension 2. which performed the proxy answer. The incoming call is connected to (step 525).

Furthermore, extension 2. has finished responding on behalf of the incoming call from extension 2f to extension 2a, extension 25 is still ringing, and extension 2. When the user executes the proxy response operation again, extension 2° is changed to the third priority information p3 through the same process as described above.
from trunk line 4 to extension 2. It is now possible to answer incoming calls on your behalf.

As is clear from the above description, according to this embodiment, extensions 2□, 2. And if you execute the proxy response operation while 2c is calling,
Inside M2. Based on the pre-registered priority order, the incoming call from office line 3 to extension 2□ can be answered by proxy with the highest priority, and then extension 2. Incoming calls from trunk line 4 to extension 2e can be answered by proxy with second priority, and finally from trunk line 4 to extension 2e. You will be able to respond to incoming calls on your behalf with third priority.

Next, in FIG. 4 as well, extensions 21.2b, 2c, 2. and 2° constitute a proxy response group G that executes the proxy response function.

In addition, the private branch exchange 1 distinguishes proxy response operations for each call type. For example, as a proxy response operation for an incoming office line call C1, after making a call, select special number 5N = 11, and select an incoming extension call C2. As a proxy response operation for the trunk line incoming call C4, select special numbers 5N-12 after making a call, and select special numbers 5N=13 after making a call as a proxy response operation for the trunk line incoming call C4. .

In such a case, by executing the registration operation of the predetermined proxy response group and call type proxy response special number from the maintenance console 17, each extension belonging to the proxy response group G is stored in the main memory (MM) 13. 21.2b, 2C12d and 2
．． The extension numbers DNa, DN, , DNe, DNd, and DN are registered as proxy answerable 131, and the special numbers 5N=11, 12, and 13 correspond to incoming calls C1 and extension calls, respectively. A proxy response possibility table 134 in which call C2 and trunk line incoming call C4 are registered is provided in advance.

In this state, a call is received from the office line 3 to extension 2□, and a call is received from the trunk line 4 to extension 2. A call arrives at extension 2. When a call arrives at extension 2c from An intermittent ringing signal that can identify incoming calls, trunk calls, and extension calls is sent to each extension 2. ．． 2. and 2c, the extension number DN of the proxy response group table 131 provided in the main memory (MM) 13.

In response to this, the call birth information indicating the incoming call from the central office line, J.
Further, call origination information L4 indicating that a call has arrived from a trunk line is set corresponding to the extension number DN, and call origination information t2 indicating that a call has been received from an extension line is set corresponding to the extension number DN.

At this time, extensions 2□, 2. and 2c are absent, extensions 2□, 2. and 2. The other extension 2゜, which noticed the incoming call to the central office line, picks up the handset in order to respond to the incoming central line call C3 with the highest priority, and then calls the special number 5N= 11, the central control unit (CC) 12 selects the subscriber circuit (LC) 14. Detects a call from extension 28 via
When it is determined that number 11 has been selected, the call type special number proxy response unit 123 is activated.

The activated call type special number proxy response unit 123 refers to the subscriber data 1328 provided in the main memory (MM) 13 corresponding to the extension 28 for which the proxy response operation has been performed, and determines which extension 22 belongs. identify the proxy response group Gp (fifth
Figure step 531).

Next, the call type special number proxy response unit 123 stores the main memory (M
M) Referring to the proxy response special number table 134 provided in the extension 13, it is identified that the special number 5N=11 selected by the extension 28 corresponds to the incoming central office line call C2 (step 53
2) Referring again to the proxy response group table 131, proxy response group G

As a result of the search, the call birth information t3 corresponds to the extension number DN.
is set, the call type special number proxy response unit 123 connects the incoming call from the office line 3 to the extension 2□ to the extension 2e that has executed the proxy response (step 53).
4).

As a result of the above, the office line 3 attempting to receive a call to the extension 2a will be responded to by proxy by another extension 28 belonging to the same proxy response group Gp.

Note that after extension 28 finishes responding as a proxy for the incoming call from office line 3 to extension 2□, extensions 2b and 2. When C2 is ringing, the extension 28 then picks up the handset and selects special number 5N=12 for proxy response to the incoming extension call in order to respond preferentially to the incoming extension call C2. Then, the central controller (CC) 12 activates the call type special number proxy response unit 123 in the same process as described above, and the activated call type special number proxy response unit 123 reads the proxy response group table 131 and Referring to the proxy response special number table 134, when the extension 2e detects an extension number DNC in which call origination information t2 indicating an incoming call from the extension designated by the special number 5N=12 is set, the call type special number proxy response unit 123 connects the incoming call from extension 2r to extension 2 to extension 28, which has executed the proxy response.

Furthermore, extension 28 is extension 2. After completing the proxy response to the incoming call from the trunk to extension 21, extension 2 is still ringing, and extension 28 performs the response operation (call origination) specified for proxy response to the incoming call from the trunk line. After that, special number 5N=
13), the same process as described above is performed to connect extension 2@ to trunk 4 specified by extension 2. It is now possible to answer incoming calls on your behalf.

As is clear from the above explanation, according to this embodiment, extension 28 connects extension 2□ belonging to the same proxy response group Gp to central office line 3.
From, extension 2. from trunk line 4, and then from extension 2c to extension 2.
．． If you execute the proxy response operation that specifies the incoming call C3 from the central office line while the office line is ringing, the incoming call from the central office line 3 to extension 2a can be answered as a proxy with the highest priority, and then the incoming call C2 from the central office line can be answered by proxy. When the specified proxy response operation is executed, an incoming call from extension 2f to extension 2c can be answered by proxy, and finally when the proxy response operation is executed to specify the trunk line incoming call C1,
It becomes possible to respond on behalf of an incoming call from the trunk line 4 to the extension line 2b.

It should be noted that FIGS. 2 to 5 are merely examples of the present invention, and for example, the structure of the proxy response group and the call type are not limited to those shown in the figures, and may be modified in many other ways. However, the effects of the present invention remain the same in either case. It goes without saying that the configuration of the private branch exchange to which the present invention is applied is not limited to that shown in the drawings.

(Effects of the Invention) As described above, according to the present invention (claim 1), the extension that has executed the proxy response operation can preferentially respond to the incoming call of the call type registered with higher priority, and According to the invention (claim 2), the extension that executes the proxy response operation can respond to an incoming call of the call type specified by the proxy response operation, and the serviceability of the private branch exchange is improved in both cases.
