To provide a direct-calling device to which an interphone can be connected so as to be capable of making a call with the exterior, and which can remotely execute updates of various data for the interphone, and a calling system.SOLUTION: A direct-calling device 10 connected to an interphone connects the interphone and a telephone 21 via a first communication line N1 on the basis of a start signal so as to be capable of calling, and downloads prescribed data that are uploaded to a cloud server via a second communication line N2 on the basis of a data signal received from a server computer 24 for management via the first communication line N1. Since conversation with the telephone 21, data communication with the server computer 24 for management, and data downloading from the cloud server are performed in independent communication forms, these can be performed in parallel. Since the stored data can be updated with the downloaded data, an operation program and so on can be kept up to date.SELECTED DRAWING: Figure 1

    【課題】インターホンを外部と通話可能に接続でき、インターホン用の各種データの更新を遠隔的に実行できる直話装置及び通話システムを提供する。【解決手段】インターホンに接続される直話装置10は、起動信号に基づきインターホンと電話機21とを第1の通信回線N1を介して通話可能に接続し、管理用サーバコンピュータ24から第1の通信回線N1を介して受信したデータ信号に基づき第2の通信回線N2を介してクラウドサーバCにアップロードされた所定のデータをダウンロードする。電話機21との通話、管理用サーバコンピュータ24とのデータ通信、クラウドサーバからのデータダウンロードは独立した通信形態で行われるため、これらを同時並行して行うことができる。ダウンロードしたデータで記憶したデータを更新できるので動作プログラム等を最新の状態に維持できる。【選択図】図1
