  • Patent number: 9986049
    Abstract: The present invention relates to systems and methods for best server selection for real-time data transmission are provided. The systems and methods include an access controller, and an application which receives information of a selection of several best servers with which to transmit real-time packets to. The application sends a request to the access controller for server information before call initiation. The access controller identifies servers with the same ISP, and then selects a regional server within this group of same ISP servers. Subsequently the geo optimizer identifies servers closest to the application from among the regional servers. The respective loads of each of the closest servers are analyzed to select only servers that are likely to provide satisfactory quality of service. A monitor within the central IDC is able to measure load conditions of each server and provide this load information to the access controller.

  • Patent number: 9935866
    Abstract: The present invention relates to systems and methods for last mile optimization for the transmission of real-time data. Pseudo-packets are sent to a last mile optimizer located at each of several ‘best’ servers. The last mile optimizers provide feedback regarding jitter, latency and packet loss of the pseudo-packets to determine quality of service for each of the servers. The server with the best quality of service is selected as the ‘single best’ server. A plurality of transporter algorithms may then be applied to pseudo-packets that are then sent to the single best server, and the quality of service for each transporter algorithm is subsequently measured for effectiveness. The transporter algorithms that are shown to be effective are combined together for the actual transmission of real-time data. Continuous monitoring of transmission quality allows for utilizing backup pathways upon detection of a problem, and negotiation of preferred transporter algorithms.

  • Patent number: 9917756
    Abstract: Systems and methods for a readiness dialog box for a call over network (CON) are provided. In some embodiments, the readiness dialog box is presented to the callers prior to the onset of the call. It presents the other participant's and their status. For example, it may indicate which participants are online, but not yet ready, those who are ready, and those not available. It also enables the caller to send messages (both preconfigured and customized) to the other participants. Once sufficient participants have joined, the call may start. Sufficiency of participants could include a quorum of individuals, may require that specific participants are ready, everyone is ready, or may be time dependent. The participant requirements may be configured by the individual setting up the call based upon call type.

  • Patent number: 9871709
    Abstract: Systems and methods for improving quality of a call over network (CON) are provided. Call quality may be improved via buffer length modulation based upon the call scenario type. Scenario detection may be based upon who speaks, and the duration of the speaking, as well as contextual analysis. Further, the call over network quality may further be improved by deploying modules over the network. The modules are intermediary vehicles between each communicator and backend servers. The modules intercept audio packets from the communicator to detect packet loss, and perform recovery of lost packets, thereby accelerating real-time audio conversations.

  • Patent number: 9838544
    Abstract: Systems and methods for improving quality of a call over network (CON) are provided. Modules may be distributed over the network at nodes. The modules monitor data quantity through the node, and data quality from one node to another. This fidelity and usage data is provided to a server where the data may be utilized to decide on how to route a call over network. The selected pathway may be decided based upon avoidance of “problem” legs where packets have historically been lost, or based upon the desire to load level data transmissions. A signal indicator for the signal quality of the networks “last mile” may be provided to the user. The last mile is the portion of the data pathway dependent upon the telephone service provider's infrastructure that cannot be rerouted around.

  • Patent number: 9787565
    Abstract: Systems and methods for a call over network (CON) with a visualized summary are provided. In some embodiments, after the call concludes, a visualized summary of the call can be generated. The summary includes any of the recording of the call, transcriptions, scenario information, speaker information and the duration each speaker was talking, etc. Scenario may be generated by comparing the call speaking pattern to known templates of call types. Additionally, participant features employed in the call may be summarized in chronological relation to the calls progression in a visual format.

  • Patent number: 9749205
    Abstract: Systems and methods for visualization of a call over network (CON) are provided. In some embodiments, the visualization of a call over network may be effectuated by three functionalities: a readiness dialog box that enables the facilitation of the call, the inclusion of visualization and participant features within the call, and a visualized summary after the call. The readiness dialog box is presented to the callers prior to the onset of the call. It presents the other participant's and their status. It also enables the caller to send messages (both preconfigured and customized) to the other participants. Once sufficient participants have joined, the call may start. Once the call starts, it may be visualized by displaying on a single or multi channels, which caller is speaking, and any additional indications they may be providing. The caller may likewise be provided a set of participant features that allow the user to interact with the call.

  • Patent number: 9479412
    Abstract: Systems and methods for improving quality of a call over network (CON) are provided. Call quality may be improved via pathway testing to determine data path quality. This may be utilized to inform buffering lengths, and also may be utilized to choose the data pathway utilized for transmitting the data. Pathway testing may employ collecting microphone data on one device, transmitting it across the various pathways, and then comparing the quality at the endpoint compared to the initial data.
