  Also, the voice switch 110 in the communication control device 120 determines whether or not the receiving terminal 304 can receive a call from the calling terminal 301 based on whether or not the receiving terminal 304 is out of the mobile communication network during the connection process. Can be determined. If the incoming call terminal 304 cannot accept a call, the mail creation server 100 can transmit the response message not only by voice but also by e-mail.

  Further, the voice exchange 110 in the communication control apparatus 120 can receive the call from the calling terminal 301 based on whether or not the answering machine is set for the calling process for the receiving terminal 304. If the call cannot be received at the receiving terminal 304, the response message can be transmitted not only by voice but also by e-mail.

  In addition, the voice exchange 110 in the communication control device 120 determines whether or not the receiving terminal 304 can receive a call from the calling terminal 301 based on whether or not the receiving terminal 304 is powered off. If the call cannot be received at the receiving terminal 304, the response message can be transmitted not only by voice but also by e-mail.

  Further, the voice exchange 110 in the communication control device 120 determines whether or not the receiving terminal 304 can receive a call from the calling terminal 301 based on whether or not the receiving terminal 304 is at a predetermined approximate position. If the incoming terminal 304 cannot accept a call, for example, when the user is in a predetermined base station area, the response message can be transmitted not only by voice but also by e-mail.

  When the voice switch 110 in the communication control device 120 is set in advance by the user of the receiving terminal 304 and cannot receive a call from the calling terminal 301 within a predetermined time, the receiving terminal 304 sends the call. If it can be determined that the terminal 301 cannot receive a call and the receiving terminal 304 cannot take a call within a predetermined time, the response message can be transmitted not only by voice but also by e-mail. it can.
