Abstract

PURPOSE:To call back a calling terminal, by storing a time incoming during incoming rejection setting and an extension number of the caller side in a main storage device corresponding to an incoming terminal equipment and reading the stored time and the extension number of the caller side at the release of incoming rejection. CONSTITUTION:When a special code by a user of an extension 101 receiving an incoming rejection signal is dialed the setting time, the extension telephone number of the telephone set 101 and the extension telephone number of the called party extension 100 are registered on an extension data storage area in the main storage device 104. When the special code is dialed to set the release of incoming rejection by the user of the extension 100 to release the incoming rejection of the extension 100, a central control unit 103 seeks the extension telephone number of the extension 100 from the called extension number registered in the main storage device 104 and when it is registered, the registration of a message from other telephone sets is informed to the extension 100 during the rejection of incoming call.

Description

[Detailed description of the invention] 3. Detailed description of the invention [Industrial application field] The present invention relates to an incoming call rejection method for an automatic exchange.

[Conventional technology]

Conventionally, with the call rejection method of the automatic switching machine in this building, even if the called party dials the extension number of the call rejection terminal to a terminal that has been set to reject calls, the intermediate control device is not blocked. [Problems to be solved by the invention] In the conventional incoming call rejection method described above, the incoming call rejection signal is sent only to the calling terminal (roll terminal) without performing the output processing to the call terminal. Even if the caller dials the extension number of the call rejection terminal for the set called terminal, the caller 11411 cannot receive the call to the called terminal simply by receiving the call rejection signal from the central control unit. As a result, the calling party may place a call to a p+ degree call rejection terminal even though the called party has set call rejection, or even if the called party has canceled the call rejection There are cases where the called party continues to cancel the call rejection without being aware of it on the calling side, and it has the disadvantage that it is difficult to communicate information between the two parties0 [Means for solving the problem] The incoming call rejection method of the present invention includes a means for storing in a main storage device, corresponding to the incoming terminal, the time and extension number of the calling party when the called terminal is set to reject incoming calls, and the extension number of the calling party. The terminal includes means for displaying the stored time and extension number of the calling party when the rejection is canceled, and means for calling back the calling terminal.

The set time, the extension telephone number (for example, '2]12'') of the temporary telephone extension phone 10 and the extension telephone number (for example '2111'') of the temporary extension telephone 00 are registered in (see figure). The user of extension telephone 00 dials the special code 192' (see Figure 3), which is registered in the main memory 04 in advance and is used to cancel the rejection of incoming calls, to reject incoming calls on extension telephone 100. When you cancel the call, the common-line telephone 100 is selected from among the extension numbers of the called party registered in the main memory 104 (see Figure 2).
The extension telephone number ``2111'' of ``2111'' is searched, and if it is registered, it is notified to the extension telephone 100 that a message has been registered from another ``Gokin terminal'' while the incoming call is being rejected. The user of the common telephone 100 dials the special code "93" (see FIG. 3) registered in the main memory 104 and reads out the calling party's extension number (for example, "2112"). Extension 1!

〔Effect of the invention〕

As explained above, in the present invention, when the calling party receives a signal from the central control unit indicating that the called party is rejecting a missed call, the time and extension number of the calling party are stored in the main memory. By registering this, when the called party cancels the call rejection, by receiving a message from the central control unit, the called party reads out the time and extension number registered in the main memory by the calling party. Since the extension number of the calling party is called back after a series of calls, the calling party only has to wait for the called party to contact him, which has the effect of saving him the trouble of repeating the calls and the time it takes to cancel the call rejection.
