  • Patent number: 9160845
    Abstract: A node in a telephone network such as a switch stores associations between called and calling parties and colored ringback media played by the called party. Later, when the same calling party calls the called party, the node retrieves the stored ringback media and forwards the media to the calling party on behalf of the called party. In one embodiment, the node comprises a switch. In other embodiments, the node is a central server caching called/calling party combinations and associated ringback media and provides the ringback media forwarding function for a distributed population of called parties. Such called parties may comprise wireless phones.

  • Patent number: 8081751
    Abstract: A method for causing a calling client station to obtain content from a network server in response to a trigger signal received by the client during the ringback period for a call. The trigger signal is transmitted from a ringback server to a calling client station during the ringback period of call setup, whereby the trigger signal, once received and recognized by the calling client station, causes the station to request and obtain content from a network server. In another aspect, a method for providing content to a calling client station by transmitting a trigger signal to the calling client station during call setup, thereafter receiving at a network-based content server a request from the calling client station, generated in response to the trigger, for a content-download, and providing the content-download in response to the request.

  • Patent number: 8059800
    Abstract: A method for the viral distribution of ringback media. A trigger is transmitted from a calling client station to a ringback server during the ringback period of call setup, whereby in response to receipt of the trigger by the ringback server, the subscriber associated with the calling client station is granted the right to the particular ringback media played out during the ringback period. Upon receiving the trigger, the ringback server may request that an indication that the right has been granted be stored in the subscriber's account record. Subsequent to the granting of the right to the particular ringback media to the subscriber, callers to the subscriber may be presented with the particular ringback. Further, these callers may also request to acquire the right to the particular media via the same trigger-initiated process.

  • Patent number: 7552058
    Abstract: Convenient and automatic methods are disclosed for reporting a violation of a do-not-call list. The only action required by the callee is to enter a predetermined touch tone pattern on their telephone key pad when they receive the call (e.g. pressing 999), and then hanging up. Network node(s) on the telephone network receive the touch tones and interpret the touch tone pattern as an indication of a violation of the do-not-call list. The network node stores the phone number of the caller, the callee number and the time of the call. The network node automatically generates and sends a notice of violation to the agency administering the do-not-call registry. In alternative embodiments, two network nodes may be involved in automatically generating and transmitting the notice of violation. The nodes may be nodes in a Signaling System 7 network.
