NIPPON TELEGRAPH AND TELEPHONE CORPORATION, “Survey Material 2000 Early Version”, [On line], August 1999, [May 16, 2003 search], Internet <URL: http: // www. ntt-east. co. jp / ISDN / tech / spec / topinx. html> Nippon Telegraph and Telephone Corporation, “Interface for Information Notification Service on Telephone Network”, [On line], August 1997, [May 16, 2003 search], Internet <URL: http: // www. ntt-east. co. jp / gisanshi / analog />

  However, when a contract user who has contracted the above-mentioned message display registration notification and / or caller ID notification service is making a VoIP call using the information receiving terminal, the message display registration notification and / or the caller is sent through the public network. When the number notification is received, the voice communication device discards the received message display registration notification and / or caller number notification, and there is a problem that the information receiving terminal is not notified.

  As shown in FIG. 3, since the communication line is connected to the information receiving terminal during the VoIP call, even if the voice communication device receives the message display registration notification and / or the caller ID notification, the information reception is performed. The communication line with the terminal cannot be used, and a situation in which the finally received message display registration notification and / or caller ID notification is discarded occurs. In addition, since the voice communication apparatus accepts the message display registration notification, the message center regards the message display registration notification as being completed, and does not retransmit the message display registration notification.

  As a method of avoiding such a situation, a communication line is used by on-hooking a public line by an information receiving terminal during a VoIP call, and a message display registration notification is sent from the message center at a predetermined cycle (for example, every 6 seconds). It is also conceivable to perform retransmission of.

  However, putting the communication line in use by off-hook occurs every time a VoIP call is made from the public network side, and when there is an interrupt incoming call from the public network side during the VoIP call, There is a risk of hindering the provision of Call Waiting Service. In addition, a contract user of the Call Waiting Service (registered trademark) cannot receive the service of the contract content, which causes a problem.

  Therefore, when the information receiving terminal to be accommodated uses a communication network different from the public network, a voice communication device and information that can be surely notified to the information receiving terminal when information is notified through the public network What is needed is a notification program and a storage medium.
