Description

  The present invention relates to a button telephone device having a function of preventing duplicate incoming calls connected to a telecommunication line (circuit switching network, IP telephone network, etc.) capable of notifying caller information (caller number, caller name, etc.). And a method for preventing duplicate calls.

In a telephone apparatus that accommodates three or more call channels and has a call transfer function, a plurality of outgoing call channels are captured in parallel at the time of an incoming call when the call transfer function is operated, and dialed in parallel to a plurality of transfer destinations. A telephone device is disclosed (for example, see Patent Document 1).
However, if the same phone number is registered intentionally or negligently at the multiple forwarding destinations, there is a duplicate incoming call from the same caller at the forwarding destination, and one incoming call can be answered, but in response to the other incoming call However, there is a problem that there is no other party to call, especially for button phone users who can display the status (incoming, in use, on hold, etc.) for each outside line. This is one factor that reduces the efficiency of business operations due to the time required to respond.

  On the other hand, in a telephone device connected to a telecommunication line capable of notifying a caller number, a caller number is stored in a memory in advance and stored as a caller number notified from the telecommunication line when an incoming call is received. There is also a telephone device that compares a caller number and executes a predetermined function when both match, and further discloses a telephone device that allows a predetermined function without registering a plurality of caller numbers (for example, , See Patent Document 2).

However, these only disclose the technology of operating the call transfer function or the answering machine function, and are measures against the above-described reduction in business efficiency for the user of the key telephone. Absent.
