Description

  The present invention relates to a dial-in incoming method for a dial-in line and a button telephone device in a local telephone facility.

  Private telephone equipment (private telephone equipment consisting of private branch exchange, internal telephone and external line, key telephone main equipment and button telephone equipment consisting of key telephone and external line, IP telephone server, IP telephone gateway or IP telephone main equipment and IP A dial-in line (refers to a line with a so-called dial-in function that can call a desired extension directly from an external line; the same applies hereinafter) to an external line of a telephone and an external line. Is connected to one extension telephone corresponding to the dial-in number (the extension telephone of the private branch exchange described above, the button telephone of the key telephone apparatus, the IP telephone of the IP telephone apparatus, etc.). After receiving an incoming call and answering the incoming call with the extension telephone, the call is terminated or a transfer operation is performed, and the extension telephone is set. As long as you do not become a free state, there is a problem that can not accept an incoming call even if it receives the same dial-in number.

  In order to solve this problem and to operate the so-called button telephone device with the private telephone apparatus, a plurality of dial-in number corresponding function buttons corresponding to the same number information are set in one extension telephone, and the same in the private branch exchange. When there are a plurality of dial-in calls with the same number information at the same time, each of the dial-in calls is associated with each of the plurality of dial-in number corresponding function buttons corresponding to the number information. It is disclosed that the state of the incoming call is displayed on the display means of the dial-in number correspondence button (see, for example, Patent Document 1).

However, setting a plurality of dial-in number function buttons corresponding to the same number information on one extension telephone means that it is necessary to support a plurality of dial-in numbers on the extension telephone. The number of function buttons increased by multiplying by “number-corresponding function button × dial-in number”, resulting in a problem that the operability of the user deteriorated as the extension telephone size increased and the number of function buttons increased.
