Zusammenfassung: | PROBLEM TO BE SOLVED: To allow an outside line device to identify a calling side user while transferring a call to the outside line device.SOLUTION: A call system includes a relay device and a called terminal. The relay device includes: a message control unit for transmitting, when a calling signal destined to a representative number, i.e. a telephone number received by the relay device is received from a calling terminal, a message including identification information on the calling terminal to a called terminal which is an outside line terminal registered as a transfer destination in advance; and a relay control unit for establishing a call between the calling terminal and the called terminal when the calling signal is received from the called terminal. The called terminal includes: a message display unit for displaying contents of a message transmitted by the relay device; and a communication control unit for transmitting a calling signal to the relay device in response to a user's operation corresponding to the message.SELECTED DRAWING: Figure 1
【課題】外線機への通話の転送を実現しつつ外線機において発信側のユーザを識別することを可能にすること。【解決手段】中継装置と、着信端末と、を備える通話システムであって、前記中継装置は、自装置で着信を受ける電話番号である代表番号宛の発呼信号が発信端末から受信されると、転送先として予め登録されている外線機である着信端末に対して、前記発信端末の識別情報を含むメッセージを送信するメッセージ制御部と、前記着信端末から発呼信号が受信されると、前記発信端末と前記着信端末との間で呼を確立する中継制御部と、を備え、前記着信端末は、前記中継装置から送信されたメッセージの内容を表示するメッセージ表示部と、前記メッセージに応じたユーザの操作に応じて、前記中継装置に対して発呼信号を送信する通信制御部と、を備える、通話システムである。【選択図】図1 |
