摘要： Establishing a connection from a caller to a user using a pre-authorized credit from the user is described. A processor identifies one or more source identifications (IDs) for receiving pre-authorized credit for the incoming call. One or more destinations are specified to receive the incoming call. The processor defines a rule associated with the one or more destinations and the one or more source IDs. An interface receives the incoming call directed to one of the destinations from the caller. A storage area stores the defined rule. The incoming call and the caller are determined as a function of the one of the destinations, one or more identified source IDs and the defined rule. The pre-authorized credit is issued for the incoming call from the caller if it is determined that the incoming call to the destination satisfies the defined rule. The processor routes the incoming call to the user.

摘要： Conferencing data is reliably delivered to computer systems participating in a hierarchically arranged multi-cast conferencing session. When a child computer system does not receive a multi-cast packet (e.g., an IP multi-cast packet), the child computer system sends a negative acknowledgment to a parent computer system. In response, the parent computer system re-transmits conferencing data that was contained in the multi-cast packet to the child computer system. Conferencing data can be re-transmitted to the child computer system via uni-cast (e.g., TCP). Accordingly, conferencing data that is not received or that is damaged via multi-cast can be repaired via uni-cast. Computer systems can join an existing multi-cast conference session without having to communicate with the root computer system. The root computer system adjusts a multi-cast send rate to compensate for changed network conditions.

摘要： Location inference using selected beacons. Data is received representing a set of beacons observed by a computing device. The beacons are located within a first geographic area. A subset (e.g., a clique) of the beacons is selected based on a coverage area of each of the beacons, where each of the beacons in the selected subset has a coverage area that overlaps with the coverage area of each of the other beacons in the selected subset. Using known or estimated positions of the beacons, a second geographic area is defined based on the selected subset of beacons and the beacon reference data and the coverage areas associated therewith. The second geographic area, smaller than the first geographic area, represents an approximate location of the computing device. In some embodiments, the computing device is calculated to be within the second geographic area with 95% probability.

摘要： The present invention generally relates to a method and system for providing VoIP clients with the ability to confirm accuracy in conversation data over a digital communication channel. More specifically, a method and system is provided for verifying, via a visual representation whether a receiving client captures accurate information from a particular portion of the digital voice conversation. In response to a triggering event, a visual representation, including information extracted from the particular portion of the digital voice conversation, may be generated for verifying the accuracy. Based on the needs of the clients engaging in the conversation, one or more visual representations and corresponding verifications can be exchanged. In this manner, a multi-tiered oral agreement with authentication may be generated over a digital communication channel.

摘要： The present invention is directed to a method and system for broadcasting a message to selected devices. More specifically, the method and system identifies appropriate VoIP devices of a recipient client suitable for a broadcast message and transmits the broadcast message to the identified appropriate VoIP devices over a digital communication channel. The appropriate VoIP devices are selected in accordance with various constraints of broadcasting such as recipient client's preference, functionality and capability of the recipient VoIP device, broadcaster's bandwidth, a set of broadcasting rules, or the like. In order to identify appropriate VoIP devices or a recipient client, the information relating to the recipient client and VoIP devices may be exchanged using the digital communication channel.

摘要： A method and system for processing received VoIP data packets based on preferences of a recipient client or capabilities of a recipient computing device is provided. Several users and/or service providers are allowed to specify rules instructing how to process contextual information upon receipt of the contextual information. More specifically, a recipient computing device may have contextual processing rules specified based on its individual need and capability. The contextual processing rules may indicate what application can be used on a certain type of contextual information. Based on the contextual processing rules, the contextual information may be stored in local storage of the recipient computing device or forwarded to another device. In this manner, each recipient computing device of the recipient client can process contextual information based on its need and capability.

摘要： Disclosed are methods that enable communications to be established regardless of the presence of communications blockers, e.g., firewalls and NATs, in the path between two computing devices. Two devices each establish communications with a rendezvous service. Through the service, the devices signal each other to set up direct, peer-to-peer communications between themselves. If the devices fail to establish direct communications, then they invoke a relay service that provides the illusion of direct communications. In another aspect, an originating device attempts to establish communications with a recipient, using an address and port number associated with the recipient. If that attempts fails, possibly because a firewall is blocking communications, then the originating device retries using a port normally held open by firewalls. If this attempt also fails, then the originating device invokes the services of a proxy to negotiate a port acceptable for use by the recipient and by any intervening firewalls.

摘要： In order to minimize the delay of the video images viewed by a network conference attendee, an intelligent buffering process (IB process) selectively discards video frames from at least one point, and in an embodiment, many network points, such as at “in” and/or “out” buffers of clients, servers, routers, etc. Packets of video frame data arrive at a buffer, which can fill to a predetermined limit if the packets cannot be forwarded due to delays or slow connections. To forward the most current video images, old frames in the buffer are discarded rather than forwarded. In a particular embodiment, when the buffer is full, the next arriving delta frame packet is discarded. To avoid distortion, each subsequent delta frame is discarded until a new key frame eventually arrives. If the buffer is still full when the key frame arrives, the buffer is purged and the new key frame is added.
