  • Patent number: 11734538
    Abstract: Systems and methods are described for low power radio devices. A first radio-based computing devices emits wireless power signals which are received by a plurality of second radio-based devices. A sensor controller of the one or more second radio-based devices determines if an interrupt signal is to be transmitted to an associated at rest microcontroller, to cause the microcontroller to prepare to receive or emit a radio information signal.

  • Patent number: 8964951
    Abstract: The present invention is related to telecommunications, and in particular to systems and methods of using telecommunication services for user authentication. Account information is stored for a user, the account information including at least a first phone number associated with the user. A user order is received. A verification phone call is received from the user, the call including charge phone number information. The charge number information is compared to the first phone number to authenticate that the user is associated with the first phone number. Based at least in part on the comparison, the user order is selectively caused to be fulfilled.

  • Patent number: 8718243
    Abstract: The present invention relates to telecommunications, and in particular, to systems and processes for processing telephone calls and providing telephony services. In one embodiment, a call processing system, compromises a first telephony interface configured to receive a call from a caller, a storage device configured to store a greeting, and a call answering system. The call answering system is configured to play the greeting in response to receiving the call, record a voice message from the caller, determine when the caller has completed recording the voice message, after determining that the caller has completed recording the voice message, play a prompt regarding the caller becoming a subscriber to call services provided by the call processing system, receive from the caller information used to establish a call services account, and establish a call services account for the caller.

  • Patent number: 8630396
    Abstract: Processes and systems for transferring communication messages, such as fax and voice messages, between a computer and a terminal are disclosed. For example, a fax message intended for a user is received at a call processing system. A voice message intended for the user is received at the call processing system. An initial portion of the fax message and the voice message are transferred to a user terminal. The user can view the initial portion of the fax message and listed in the initial portion of the voice message using the user terminal. At least a second portion of the fax message is downloaded to the user terminal in a trickle mode, and at least a second portion of the voice message is downloaded to the user terminal in a trickle mode.

  • Patent number: 8472604
    Abstract: The present invention provides flexible, user-definable call screening processes. The user can optionally define to which telecommunication terminals a screened call is to be broadcast to and under what conditions. An incoming call is forwarded to a call management system that asks the caller to leave a voice message. The call management system selectively couples the call to a POTS line or a VoIP-capable device so that the user can listen to the incoming message and thereby screen the incoming call. Based on the screening, the user can instruct the call management system to connect the caller to the user.

  • Patent number: 8401163
    Abstract: The present invention is related to telecommunications, and in particular, to methods and systems for call processing. By way of example, a first call control is visually provided via a Web page in association with search results transmitted to a user computer system, wherein the user submitted to search request to a search engine. An indication is received that the user activated the first call control. A first call is placed to a telephonic address selected by the user. A second call is placed to a telephonic address associated with the first call control. Progress information related to the second call is transmitted to the user computer system in substantially real-time.

  • Patent number: 8165572
    Abstract: Methods and systems are described for routing call in a wireless network environment. In one embodiment, a phone address is assigned to a subscriber and/or a subscriber's mobile telecommunications device. A call directed to the phone address is routed to a call processing system. An outbound call from the call processing system is placed to a wireless communication service provider so as to cause, at least in part, the wireless communication service provider to route the outbound call to the subscriber's mobile telecommunications device, wherein the call processing system configures call signaling parameters associated with the outbound call so that the outbound call appears to be to a phone number ported to the wireless communication service provider, and wherein the phone number has not been ported to the wireless communication service provider. The outbound call is bridged with the inbound call.

  • Publication number: 20110007885
    Abstract: In an illustrative embodiment, methods and systems are provided for processing facsimiles. A call processing system receives a first message transmitted from a first carrier system regarding a facsimile call to a phone address. The first message includes an identifier associated with the user. The identifier is used to determine if the user is authorized to receive call processing system services. If the user is authorized, a second message is transmitted to the first carrier system, the second message indicating that the first carrier system is to connect the call to the call processing system. The call processing system is connected to the call. A facsimile is received via the call at the call processing system. Information regarding the facsimile call is provided over a network, wherein some or all of the information is displayed in a call log visually accessible by the user.
