PROBLEM TO BE SOLVED: To provide an intercom system suitable for the user of portable communication terminal to respond under an environment where it is difficult to speak, in an intercom system capable of remote unlocking by using a portable communication terminal in place of intercom master unit.SOLUTION: An interphone 10 transmits notification data NF to an authentication server 20 in response to depression of a call button. In response to reception of the notification data NF, the authentication server 20 performs authentication processing and transmits a call notification CR to a portable communication terminal 30 of alternative call destination based on the authentication results, and then connects the portable communication terminal 30, transmitted a response request Req for this call notification CR, and the IP slave unit of the interphone 10 to enable video calling. When a routine sentence response mode has been set, the portable communication terminal 30 performs indirect responce using a routine sentence voice message, previously registered in the own terminal, in the telephone conversation with the IP slave unit.SELECTED DRAWING: Figure 11 【課題】携帯通信端末をインターホン親機の代わりに使用して遠隔で開錠を行うことが可能なインターホンシステムにおいて、携帯通信端末の利用者が発話しにくい環境下で応答を行うのに好適なインターホンシステムを提供する。【解決手段】インターホン１０は、呼出ボタンの押下に応じて通知データＮＦを認証サーバ２０に送信する。認証サーバ２０は、通知データＮＦを受信したことに応じて、認証処理を行いその認証結果に基づき呼出通知ＣＲを代替呼出先の携帯通信端末３０に送信し、この呼出通知ＣＲに対して応答要求Ｒｅｑを送信してきた携帯通信端末３０とインターホン１０のＩＰ子機とを両者が動画通話可能に接続する。携帯通信端末３０は、定型文応答モードが設定されているときに、ＩＰ子機との間の通話において、自端末に予め登録された定型文の音声メッセージを用いた間接的な応答を行う。【選択図】図１１
