  • Patent number: 9307036
    Abstract: A method and system for web access using a cross-domain cookie that uses a cookie server to generate a public cookie which uniquely identifies a client and is adapted for the client to access multiple operator servers that are recognized by the public cookie. When an operator server receives an access request from the client without a valid public cookie recognizing the operator server, it redirects the access request to the cookie server, which generates a public cookie, redirects the access request back to the operator server and passes along the public cookie. The operator server then writes the public cookie into the client and binds itself with the public cookie. A public cookie may include a group of related cookies identifying the common client that are generated this way to allow the same client's activities to be tracked by different operator servers having different domain names over the Internet.

  • Patent number: 8351421
    Abstract: A system and method for sending long distance telephone calls over the Internet utilizes cost and quality of service data to optimize system performance and to minimize the cost of completing the calls. The system utilizes a network of gateways connected to the Internet. The gateways receive calls from various service providers and convert the analog calls into data packets which are then placed onto the Internet. Similarly, the gateways take data packets off the Internet, convert the data packets back into analog format, and provide the analog telephone calls to the same or another service provider. Then system periodically checks the quality of communications between each of the gateways, and uses this information, in combination with cost information, to determine how to route the calls over the Internet. Special addressing protocols can be used by a system embodying the invention to reduce or eliminate unnecessary signaling between gateways as call setup procedures are carried out.

  • Patent number: 8290137
    Abstract: In a Voice Over Internet Protocol (VoIP) system for completing telephone calls over the Internet, the system uses a general routing table and client exception routing tables to instruct originating gateways about how to complete calls. When a call request for a particular client is received, the system first looks to that client's exception routing table to see if routing information for the call is available. If so, the system will use the routing information in the client's exception routing table to complete the call. The routing information in the client's exception routing table could include information about preferred destination gateways and/or preferred Internet Service Providers. If the client's exception routing table does not contain information that could be used to route the call, then the system simply uses the routing information in the general routing table. In some situations, the system could utilize multiple general routing tables.
