Description

  The present invention relates to a button telephone apparatus, and more particularly to a button telephone apparatus capable of receiving transfer source number information by a voice warp service provided by a public ISDN (integrated services digital network) line network and a transfer method thereof. .

  As is well known in this technical field, a key telephone apparatus includes a main apparatus connected to at least one office line (external line), and a plurality of button telephones connected to the main apparatus via communication lines and data lines. (For example, refer to Patent Document 1).

  Conventionally, a button telephone device having a transfer function has been proposed. For example, “a method of transferring an incoming call in a button telephone exchange system” is known (for example, for determining a situation where a transfer call has been transferred and a transfer setting person's situation from there) (for example, Patent Document 2). In Patent Document 2, an incoming call transfer from one extension telephone to another extension telephone is set, and the transfer reason and the extension name of the transfer source are displayed on the transfer destination extension telephone when the set incoming call is transferred. I have to. In Patent Document 2, a transfer source extension telephone sets a text message, and the information is displayed on the transfer destination extension telephone.

  In addition, a “private branch exchange and private branch transfer method” that enables more efficient inheritance is also known (for example, see Patent Document 3). In Patent Document 3, a caller number notified from a local line is received, a transfer destination of grouped caller numbers including the caller number is selected, and incoming calls are distributed. More specifically, in Patent Document 3, the memory unit stores transfer destination telephone numbers grouped by caller number in a table for each extension. The modem signal receiving circuit receives the caller number notified from the office line, and the central control unit controls the automatic transfer operation. This control is executed by selecting a transfer destination number corresponding to the caller number in which the received caller number is stored based on the table data stored in the memory unit.

  In addition, a “button telephone terminal device” that can display the incoming call according to the telephone number of the transfer source can be distinguished from the normal incoming call display using the transfer source number information included in the ISDN message from the ISDN line. It has been proposed (see, for example, Patent Document 4). In Patent Document 4, when an incoming call is received, a test is performed to determine whether the content of the transfer source number information element included in the ISDN message matches the number set in the main device, and the result of the test is YES In this case, the incoming call processing is performed by a sound that is designated in advance so as to correspond to the contents of the transfer source number information element at that time.

  In addition, a technical idea is known in which a facsimile incoming call is transferred to a transfer destination using a transfer function after answering a voice warp service (see, for example, Patent Document 5). In Patent Document 5, a facsimile incoming call is directly transferred to a predetermined transfer destination by using a post-response transfer function of a voice warp service provided by NTT (Nippon Telegraph and Telephone Corporation). In Patent Document 5, the facsimile apparatus includes a RAM that stores a transfer setting table for setting whether to transfer a facsimile incoming call for each transmission source and for each time period. When receiving a facsimile incoming call, the main control unit determines whether or not to forward the facsimile incoming call based on the transmission source and time zone of the transfer setting table, and performs processing of the determined transfer mode. Running.

  Furthermore, by selecting the caller ID information transmitted from the network when an external line is received and the transfer destination according to the state of the transfer destination telephone, the caller can efficiently transfer to the optimal telephone according to the situation of the callee. A “button telephone device” has been proposed (see, for example, Patent Document 6). In Patent Document 6, when a call is transferred to a destination telephone or a destination line based on a caller number included in incoming information, the destination is selected according to the state of the destination telephone. In addition, the button telephone apparatus disclosed in Patent Document 6 can be received within a certain period of time after the incoming / forwarding means makes a call to the destination telephone or transfers to the destination line according to the comparison result of the incoming call processing means. It has a response monitoring means for determining whether or not there is a response from the destination, and performing a line connection process when there is a response within a predetermined time, and if the response is not received within a certain time, a new incoming call process is performed by the incoming call processing means. Further, in Patent Document 6, the incoming / transfer means transfers the caller ID information when the incoming call is received by the destination telephone or transferred to the destination line according to the comparison result of the incoming call processing means. Yes.
