Abstract: According to one embodiment, a communication apparatus includes specifying section which specifies sound devices/camera devices connected to a body, reading out section which reads out voice parameters/video parameters when the voice parameter/video parameter corresponding to the specified sound devices/camera devices are stored in the voice parameter storage/the video parameter storage, saving section which saves the voice parameters/video parameters decided in response to executions of voice/video communications in a voice parameter storage/a video parameter storage when the voice parameters/video parameters corresponding to the specified sound devices/camera devices are not stored in the voice parameter storage/the video parameter storage, and adjusting section which adjusts reception setting increased/decreased by the communication software and transmission setting increased/decreased by the communication software when the read out reception volume setting and the transmission volume setting are different

Abstract: According to one embodiment, a server apparatus includes an acquiring unit to acquire more than one items of data reception address information included in a data area of a message from each data terminal in connecting the data terminals with one another, a specifying unit to specify address information to receive a data communication based on the data reception address information and address information of a destination of the message, and a notifying unit to notify instruction information to instruct that the address information should be used for the data communication to the data terminal.

Abstract: To provide a voice communication terminal for executing voice communication via an Internet Protocol network comprises, a presence confirmation request signal transmission unit which transmits a presence confirmation request signal indicating presence of the voice communication terminal to a server connected to the Internet Protocol network, a response time detection unit which detects a response time from the presence confirmation request signal is transmitted until the receipt of a response signal from the server, a communication quality estimation unit which estimates a current communication quality of the Internet Protocol network related to the voice communication in accordance with the response time detected by the detection unit, and a quality information output unit which outputs information on the estimated communication quality.

Abstract: An information processing apparatus comprising a display unit which displays, on a display screen, a first display area displaying a first buttons and a second display area displaying a second buttons, a sensing unit which senses a touched position on the display screen, and a first display control unit which, when the first display area is touched, enlarging the size of each of the first buttons, expanding the size of the first display area such that the first buttons are arranged in the first display area, reducing the size of the second display area, and reducing the size of each of at least specific buttons of the second buttons such that the specific buttons are arranged in the reduced second display area.

Abstract: A computer program, which is used to voice talking to cause an information terminal to execute voice talking, managing an ID of the information terminal and a first address over a first network, stores instructions for execution on a computer system enabling the computer system to perform determining that the information terminal moves over a second network which is different from the first network, acquiring a second address over the second network, and transmitting a request for re-registering a combination of the second address and the ID instead of the first address into another device having a combination of the first address and the ID registered therein.

Abstract: A sound element database is installed in an analog telephone hub. When hold operation or the like is performed on an analog telephone during voice communication, the analog telephone hub selectively reads out necessary sound element data from the sound element database, and sends the sound element data or the type information of the sound element data to an analog telephone on the held party side through a LAN. In an analog telephone hub on the held part side, an audible sound is generated on the basis of sound element data read out from the sound element database on the basis of the sent sound element data or the sound element data type information. This audible sound is supplied to the analog telephone on the held party side to be output. With this operation, an audible sound indicating the operation state of a communication terminal can be effectively transmitted to the communication terminal of the other party.
