摘要： A personal information device (PID) is coupled to an IP Telephony phone in order to provide end-to-end connectivity to another PID through a network. The architecture disclosed includes a pair of internet-enabled phones that are able to establish a call session using a Session Initiation Protocol (SIP) and a Session Description Protocol (SDP). Each phone is also provided with an interface configured to communicate with a PID. Each PID is registered to a corresponding internet-enabled phone using each PID user's SIP URL. The user of a first PID connected to a first phone requests a call to a SIP URL corresponding to the user of the second PID that is connected to a second phone. The SIP URL for the user of the second PID is resolved to the network address of the second phone and connection is established between the first and second phones. The connection includes a media stream for transferring data between each of the PIDs. A data object transmitted by the first PID through its interface with the first phone is transmitted to the second phone through the media stream of the connection between the first and second phones. The data object received by the second phone is transmitted to the second PID through the interface between the second phone and the second PID.

摘要： A system for automatically populating an IP telephony address mapper with mapping information for an IP telephony gateway or other device. A self-registering gateway is configured to automatically provide an address mapper with mapping indicia defining the IP address of the gateway and the telephone numbers served by the gateway. In one embodiment, for instance, the gateway places a PSTN modem-to-modem call to the address mapper and conveys its IP address as a modulated data stream, while the address mapper may determine the telephone number of the gateway through established automatic calling number delivery procedures. Based on the telephone number of the gateway, the address mapper may then refer to a telephone number mapping database to identify other telephone numbers that could be served by the gateway. The address mapper may then update its address mapping data files accordingly.

摘要： A system and method for providing call handling services on a data network telephony system. A portable information device, such as a PDA, associated with a user contains the user's address and/or appointment book information. The address and/or appointment book information includes priority information comprising one or more address/appointment entries having associated priority levels. The priority information is transmitted from the portable information device across a link to a data network telephone or other voice communication device, where it is stored in a call handling database. When an incoming call request is received at the data network telephone, the call is handled according to the priority information contained in the call handling database.

摘要： A method and apparatus for controlling the transmission of real-time media signals over a data network based on a triggering event associated with a participating teleconference station. This triggering event may be the presence or absence of motion, the presence or absence of sound, or any of a variety of other events that preferably indicate the presence or absence of a person at the station. When no person is present at the station and/or when an appropriate triggering event occurs, remote teleconference participants will not transmit media signals over the network to the station, thereby conserving valuable network bandwidth and simulating a physically common meeting between people. In turn, when a person is present at the station and/or when another appropriate triggering event occurs, remote teleconference participants may start transmitting media signals over the network to the station. Additionally, a station may control its own transmission of media signals to remote stations in response to local triggering events, thus further conserving network resources.

摘要： A system and method for providing user mobility services on a data network telephony system. User attributes may be transmitted from a portable information device, such as a personal digital assistant, to a voice communication device, such as an Ethernet-based telephone. The voice communication device receives the user attributes from the portable information device and may transmit a registration request to a registration server. The registration request may include the user attributes, and is used by the registration server to register the user to the voice communication device in a registration data base. When a call is placed to the user, the registration server may reference the registration data base to direct the call to the voice communication device.

摘要： A toll saving method and apparatus for a remote access system is provided. A first communication device receives a connection request from a second communication device. The first communication device then decodes caller identification information from the connection request to determine a user identity, without completing the connection request. The first communication device determines whether an event associated with the user identity has occurred. If the event associated with the user identity has not occurred, the connection request is not completed. In a preferred embodiment, the toll saving method and apparatus allows an email user to call an ISP to determine whether unaccessed email is present in the user's account. If no email is present in the user's account, the call is never answered and no toll charges are incurred.

摘要： A method and apparatus for communicating a real time media input over a network. The apparatus encodes the input into data packets having a number of frames ordered according to a first variable. A receiving device unpacks and buffers the unpacked data packets for playout according to a second variable. The receiving device generates utility parameters for evaluating a dynamic characteristic of the network that transports the data packets. The receiving device selects a preferred utility parameter and adjusts the first and second variable according to the selected utility parameter. The method includes encoding an analog input into data packets that are transported to a receiving device. The method also includes unpacking the data packets, buffering the unpacked data packets according to a second variable, and generating at least two utility parameters that represent a dynamic characteristic of a network. The method also includes selecting a preferred utility parameter and adjusting the first and the second variables according to the selected preferred utility parameter.

摘要： A system and method for Internet telephony between a caller station and a callee station are described. The caller station is connected to a first edge network via a first telephony interface, and the callee station is connected to a second edge network via a second telephony interface. An intermediate network is connected to the first edge network via a first router and is connected to the second edge network via a second router. The callee station is associated with a callee station number. The first router initiates the call in response to a setup message that includes the callee station number. A first gatekeeper, controlling the first router, and a second gatekeeper, controlling the second router, together mediate the process of setting up the call. A back end server, in communication with the first and second gatekeepers, stores the addresses and station numbers needed to set up the call. During the call, the first router performs network address translation to transmit signals between the first edge network and the Internet, and the second router performs network address translation to transmit signals between the second edge network and the Internet.
