20080198840 | IP EXTENSION PHONE SYSTEM AND SERVER SYSTEM - There is provided an IP extension phone system including: a first server; a second server; and a portable IP phone, wherein when the second server detects connection of the portable IP phone, the second server assigns an IP address corresponding to the connected position to the portable IP phone, the portable IP phone registers the IP address in the first server, and the first server records an extension number and the IP address of the portable IP phone in an extension number management table and further records the extension number in a group management table while associating the extension number with a group corresponding to a segment of the IP address. | 08-21-2008 |
20090063626 | CALL MANAGEMENT SYSTEM, CALL MANAGEMENT METHOD, MANAGEMENT SERVER, CLIENT SERVER, CLIENT TERMINAL, AND CALL DEVICE - A call management system is configured of a client terminal | 03-05-2009 |
20090115839 | IP TELECOMMUNICATION SYSTEM, METHOD FOR CONTROLLING COMMUNICATION IN IP NETWORK, CLIENT TERMINAL AND CLIENT SERVER - A network communication system when a call is issued from one of said input/output terminal and said communication terminal, said call control means provided on the side of said server establishes the call connection between said input/output terminal and said communication terminal; and when the call connection between said input/output terminal and said communication terminal is established based upon the call control means on the side of said server, a communication of any one, or both said audio and video information can be performed via said network between said input/output terminal and said communication terminal. | 05-07-2009 |
20090185553 | TELEPHONY SYSTEM - In IP telephony systems, it has become impossible to detect the location of installation of a telephone terminal from the telephone number, since an IP telephone terminal can be installed in an arbitrary location. Also, even if one observes the calling party number presentation at the time of an incoming call, it has become impossible to grasp from where the calling party is placing the outgoing call. It is possible that, within an IP telephony system, a terminal location detection means is configured and the installation location of a telephone terminal is detected simultaneously with the registration of the telephone terminal. In addition, the problem can be solved by configuring, in an IP telephony server, a device of reporting location information about the correspondent to the telephone terminal and by configuring, in the telephone terminal, a device of displaying the received positional information. | 07-23-2009 |
20100232423 | IP PHONE SYSTEM AND IP PHONE TERMINAL REGISTRATION METHOD - A registration method of a voice terminal in a call connecting apparatus, wherein; when a registration request of said voice terminal including a first distinguishing information is received, said call connecting apparatus refers to a storage unit which stores distinguishing information and telephone number of said voice terminal; said call connecting apparatus judges whether there is a distinguishing information that is consist with said first distinguishing information; and when there is no consisted distinguishing information, said call connecting apparatus registers said first distinguishing information in said storage unit with correspondence to a telephone number which is not taken correspondence to any said distinguishing information. | 09-16-2010 |
20100274842 | BUDDY LIST GENERATION METHOD - A registration content of a buddy list must be updated by a user in a presence system according to the prior art whenever a change of the organization of the user or that of a buddy occurs. A remote companion or buddy to be got in contact with changes, when the position of duty changes such as business trip or telecommuting. A presence server according to the invention includes an action record unit for recording actual use record such as a communication function and a buddy list generation unit capable of automatically generating a suitable buddy list on the basis of use record data for managing an action use record and use record data. | 10-28-2010 |
20100322234 | IP TELECOMMUNICATION SYSTEM, METHOD FOR CONTROLLING COMMUNICATION IN IP NETWORK, CLIENT TERMINAL AND CLIENT SERVER - A terminal including: a remote control section for transmitting and receiving data with respect to a main device which performs call control processing with a target device via a telephony server in place of the terminal; and a call communication section for performing audio communication with the target device, wherein the remote control section transmits a command including a calling request for the target device and an IP address of the terminal to the main device, and receives an IP address of the target device from the main device, and the call control section performs audio communication with the target device using the IP address of the terminal and the IP address of the target device. | 12-23-2010 |
20110103375 | IP TELECOMMUNICATION SYSTEM, METHOD FOR CONTROLLING COMMUNICATION IN IP NETWORK, CLIENT TERMINAL AND CLIENT SERVER - A communication system including: a main device comprising a call control section for setting-up a call connection and a remote control section. The remote control section of the main device receives a command including calling request for the target device and IP address of the terminal from the remote control section of the terminal. The call control section of the main device transmits a call control message including the IP address of the terminal to the target device via a telephony server and receives IP address of the target device in response to the call control message. The remote control section of the main device transmits the IP address of the target device to the terminal. The call control section of the terminal performs audio communication with the target device using the IP address of the terminal and the IP address of the target device. | 05-05-2011 |
