Abstract

PURPOSE:To prevent recording of a message with low priority and to reduce the reproduction time of a recorded message from other subscriber by designating a subscriber for recording when an incoming call from other subscriber is transferred automatically to a voice storage device and recorded therein. CONSTITUTION:A control signal path 16 connects both central controllers 11, 13 provided respectively to a private branch of exchange 10 and a voice storage device 12 and exchange control information is sent and received in terms of the pulse. A message recording enable registration table 14 records plural extension numbers enabling the recording of an incoming call respectively. Then a central controller 13 of the voice storage device receives incoming notice information including a caller extension number from a central controller 11 of the private branch of exchange, a caller extension number included in the incoming notice information is retrieved and the presence of a called party extension telephone number is retrieved from the message recording enable registration table 14 to permit the recording of the message to the called party. Thus, the recording of a message with low priority is prevented and the reproduction time of the recorded message from the other subscriber is shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic forwarding service of a private branch exchange, and more particularly to a message recording system during automatic forwarding.

[Conventional technology]

Conventionally, the message recording method for this type of automatic forwarding has been a method of choosing between recording all incoming calls that arrive at the extension telephone number registered in advance for forwarding.

[Problem to be solved by the invention]

The conventional message recording method described above was a two-way system, either recording all incoming calls or refusing to record all incoming calls. If you do so, all incoming calls to that extension number will be recorded. Therefore, when the subscriber listens to the messages recorded in the voice storage device, it includes low-priority messages that the subscriber does not necessarily need, and moreover, the subscriber does not need to listen to all the recorded messages from the beginning. The drawback was that the messages could not be identified. Furthermore, there is a risk that the inclusion of messages with low priority will cause the storage area to become full due to the predetermined recording time being exceeded, making it impossible to record messages with high priority. Furthermore, there is a drawback that the limited recording medium cannot be used effectively.

The purpose of the present invention is to allow a subscriber to register in advance the subscriber numbers of multiple extension subscribers that the subscriber considers important, and to automatically transfer and record only incoming calls from registered subscribers to a voice storage device. The object of the present invention is to provide a message recording method.

[Means to solve the problem]

The message recording method of the present invention is a message recording method in which a private telephone exchange and a voice storage device are connected, an incoming call received by the private telephone exchange is automatically transferred to the voice storage device, and a message of the incoming call is recorded. , a control signal path is provided between the private telephone exchange and the voice storage device for connecting both central control devices and transmitting and receiving exchange control information;
It has a message recording permission registration table in which a plurality of extension numbers for which recording of the incoming call is permitted is registered in correspondence with each extension number layer, and the voice storage device central control device connects the incoming call to the premises telephone via the control signal path. The received call notification information including the calling party's extension number is received from the exchange control device, the called party's extension number included in the call receiving notification information is searched, and the called party's extension telephone number is retrieved from the message recording permission registration table. The system is configured to search for the presence or absence of a number and to permit recording of a message to the called party.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

FIG. 2 is a diagram showing the structure of a table of incoming call notification information showing an embodiment of the present invention, FIG. 3 is a structure diagram of a message recording permission registration table showing an embodiment of the invention, and FIG. 4 shows the message recording permission registration table shown in FIG. 3. FIG. 3 is a diagram illustrating a configuration of recording permission subscriber numbers in a recording permission registration table in which subscriber numbers are individually registered;

FIG. 1 shows a private telephone exchange 10 having a central control unit 11.
and a central control unit 13. A voice storage device 12 having a message recording permission registration table 14 and a private telephone exchange 1
0 and the voice storage device 12, a control signal path 16 that connects the central control devices of both the private telephone exchange 10 and the voice storage device 12, and the private telephone exchange 1
It consists of extension telephones 17 and 18 housed in 0.

All incoming calls from subscriber B's extension telephone 18 to the subscriber number assigned to subscriber A on extension telephone 17 are automatically transferred to and stored in the message storage section (not shown) of voice storage bag [12]. It is assumed that it is registered.

When subscriber B dials the subscriber number of subscriber A from the extension telephone 18, the central control unit 1 of the private branch telephone exchange 10
1 detects this incoming call and transfers the incoming call to the voice storage device 12 via the communication path 15. At the same time, the central control unit 11 of the private branch telephone exchange 10 sends an identifier 20. Subscriber number field 21 of subscriber A who has configured automatic transfer settings. Incoming call notification information consisting of the subscriber number field 22 of the calling subscriber B is sent to the central control unit 13 of the voice storage device 12 via the control signal path 16. The central control device 13 of the voice control device 12 recognizes the subscriber number of subscriber A from the subscriber number field 21 of the incoming call notification information, searches the message recording permission registration table 14, and performs the subscription shown in FIG. The message recording permission registration table shown in FIG. 3, which reads out the recording permission registration table registered corresponding to the subscriber numbers of persons A, B, . . . m, is as follows:
Subscriber number field 30.31.Subscriber number field in which the subscriber number of the subscriber who has authorized transfer/recording of incoming calls is registered. :・・m
It is made up of. Central control device 1 of audio storage device 12
3 recognizes the subscriber number of subscriber A from the incoming call notification information and reads out the subscriber number field 30 in which the subscriber number of subscriber A is registered from the recording permission registration table of FIG. As shown in FIG. 4, the subscriber number field 30 contains the subscriber number of the caller for whom subscriber A has permitted recording.
For example, the central control unit 13 of the voice storage device 12 searches the subscriber number of the subscriber B who is the calling party registered in the calling party number field 22 from the incoming call notification information. If the subscriber number of subscriber B is X100, the calling subscriber number X100 registered in the subscriber number field 42 in FIG. During this time, a call path is set up via the call path 15, and a message addressed to subscriber A is recorded from the extension telephone 18 in the message storage section of the voice storage device.

〔Effect of the invention〕

As explained above, when a subscriber automatically forwards incoming calls from other subscribers to the voice storage device and records them, the subscriber can specify the subscriber to be recorded, which prevents low-priority messages from being recorded. This has the effect of shortening the playback time of recorded messages from other subscribers.
