  • Patent number: 9037451
    Abstract: A system for managing voice communications provides voice prompts in one or more particular languages or language variants. High level grammatical rules are defined for the set of voice prompts in the particular language. The grammatical rules for the set of voice prompts are stored in the system. A set of audio tiles are developed in the particular language. The audio files in the particular language are stored in the system. A request is received from a user, and the system initiates a request for a voice prompt. A sequential list of audio files is developed, and when the sequential list of audio files is played by the system, the requested voice prompt is played to the user in the particular language. The sequential list of audio files is produced based on the grammatical rules and voice communications are managed in the system.

  • Patent number: 7596461
    Abstract: A system for measuring air quality in wireless networks. In particular implementations, a method includes computing an interference severity level for a plurality of interference sources detected at an access point; aggregating one or more of the computed interference severity levels relative to the access point; and computing an air quality metric for the access point, wherein the air quality metric based at least in part on an equation: 1—aggregated interference severity level.

  • Patent number: 7181401
    Abstract: Systems and methods by which voice/data communications may occur in multiple modes/protocols are disclosed. In particular, systems and methods are provided for multiple native mode/protocol voice and data transmissions and receptions with a computing system having a multi-bus structure, including, for example, a TDM bus and a packet bus, and multi-protocol framing engines. Such systems preferably include subsystem functions such as PBX, voice mail and other telephony functions, LAN hub and data router. In preferred embodiments, a TDM bus and a packet bus are intelligently bridged and managed, thereby enabling such multiple mode/protocol voice and data transmissions to be intelligently managed and controlled with a single, integrated system. A computer or other processor includes a local area network controller, which provides routing and hub(s) for one or more packet networks. The computer also is coupled to a buffer/framer, which serves to frame/deframe data to/from the computer from TDM bus.
