  • Patent number: 8934610
    Abstract: A file management system that transmits a record file of voice data or image data created by a local device to a center device over a network and manages the record file in the center device. The center device receives attribute information about the record file, including the ID of the record file, which is created in the local device, further acquires extended attribute information associated with the attribute information from a PBX, call control server, or customer server, stores management table including the attribute information and the extended attribute information. The extended attribute information of the record file suggests frequency of the reference for the record file in the local device. The center device decides the timing of the upload request for the record file based on the extended attribute information of the record file.

  • Publication number: 20140089353
    Abstract: In a file management system that a record file created in a local place is managed in a center, a local device creates a record file of voice data or image data, creates an attribute file indicating the attribute of the record file, stores the record file in a local storage and transmits first the attribute file to a center device. The center device registers information on the attribute file including information indicating the location of the record file into a management table. Then, the local device transmits the record file to the center device in a time zone that a network load is small. When the record file corresponding to the received attribute information is received, the center device changes the storage location of the record file in the management information in the management table.

  • Patent number: 6078583
    Abstract: A communication system and communication method adapted so that the user of one of the communication terminals can more easily communicate with another one connected to the internet through the public network. Connection management servers for relay and manage the communication are provided at nodes between the internet and the public network. Each of the connection management servers assigns an IP address to the communication terminal connected to the internet through the public network, and registers the IP address and the telephone number. When receiving a communication request, the connection management server specifies a communication route to the communication terminal on the basis of the telephone number of the called-side communication terminal set in the communication request. The server checks if the called-side communication terminal is connected to the internet on the basis of the above registration. If it is connected to the internet, the server relays the communication request.

  • Patent number: 5905495
    Abstract: A communication system which can communicate with a party user even when an originator user of a communication terminal does not know the terminal address of a communication terminal of the party user with whom the originator user wants to communicate. When its own user A does not know the terminal address of a communication terminal of a user B, a communication terminal of the user A sends an outgoing file having its own terminal address stored therein as an electronic mail directed to the user B. When receiving the outgoing file as the electronic mail, the communication terminal of the user B displays an icon on its display unit to prompt the user B to enter an instruction of performing reply communication. In response to it, when the user B clicks a mouse on the icon, the communication terminal of the user B can perform the reply communication to the communication terminal corresponding to terminal address stored in the outgoing file.

  • Patent number: 5758082
    Abstract: In mail terminal equipment for receiving and reproducing a mail which has been produced using multi-media data containing a plurality of continuous audio data and a plurality of drawing data synchronized with at least a part of the audio data and has been transmitted thereto. Where reproduction of the drawing data is later than that if the audio data, the drawing data is synchronized with the audio data without interrupting reproduction of the audio data. When the drawing data still remains which at certain timing (e.g., timing when supplementing the audio data to a audio buffer for storing the audio data waiting for reproduction), should be reproduced until that time point, but is not reproduced resulting from the delay of reproduction of the drawing data due to the drawing processing, the loading situation and the like, the drawing data of interest is skipped so as not to be reproduced, and the next drawing data is reproduced.
