  • Patent number: 8830878
    Abstract: Techniques are described for better ensuring that calls or transmissions directed to a subscriber or endpoint to which a number was previously assigned are not received by a new subscriber or endpoint. According to one class of implementations, a telephony platform maintains a registry that associates a secondary identifier with each phone number that is currently assigned to a subscriber. The identifier may point to and/or include any of a variety of information that maps to the current subscriber. When a calling party initiates a call to an assigned number, an additional identifier is transmitted with the call routing information that corresponds to the entity or endpoint to which the call is directed. The telephony platform makes call routing decisions based on the correspondence of this information with the information maintained in the registry.

  • Publication number: 20140064460
    Abstract: A logic history can be provided for every request or call instance through a distributed computing system that uniquely traces its entire path, end-to-end, in-band within the messaging for the system. The end result is a single true representation of what occurred with no post computational inference. Accordingly, unique logic history codes are not forced across the system. Rather sub-components that are logic history enabled can use codes that have meaning and applicability to itself. Unique logic history codes are not forced across the system, which in practice would be brittle. Rather each sub-component that is logic history enabled can use codes that have meaning and applicability only to itself. This allows the system to be flexible and lets sub-components change and redefine their logic and logic history traces without impacting the rest of the system.

    Abstract: A system and method for tracking call activity of a plurality of businesses is disclosed. A global pool of phone numbers is allocated from which to draw numbers. A business-specific pool of numbers is established for business locations involved in advertisements using the Internet via Web pages. As a consumer begins viewing an advertisement for a business, a number is temporarily allocated from the business's pool of available numbers. As the business's pool of unallocated numbers is exhausted, a metric is used to determine whether or not to grow the pool of numbers, to show an untracked ‘fallback’ number for the business, or to reuse a previously allocated number. When one of the temporarily allocated numbers is called, the online consumer it was associated with is credited for making the call and the business is credited and charged for receiving the call.

    Abstract: Methods and systems for intelligent signaling-router-based surveillance are disclosed. A surveillance and signaling router receives call signaling messages, identifies call signaling messages associated with users under surveillance and determines a surveillance type for the call signaling messages. If the surveillance type is content-related, the surveillance and signaling router forwards the message to a call server. The call server replaces parameters in the message and in subsequent messages so that the call is transparently set up through a media proxy server. The media proxy server copies the media stream to a delivery function. If the surveillance type is non-content-related, the surveillance and signaling router sends a copy of the message or information extracted from the message to an external device.

  • Patent number: 7050549
    Abstract: A system for testing and monitoring the operation of telephone systems uses a call trace method for capturing messages associated with a phone call. The system can provide an indication as to the time a particular triggering signaling message (e.g., IAM or RLC message) was detected on a link. The present system assembles SS7 signaling messages in real-time. Time stamps are employed in triggers to identify past messages stored in a buffer that are related to the phone call.

  • Patent number: 6980821
    Abstract: A dispatch based call system configured to contact a call center using a single unique name or number. Multiple users are able to simultaneously dispatch the single generic call center number and communicate with a unique end station or individual at the call center. A user, or subscriber unit, when dispatching a call communicates initially with the service provider infrastructure. The infrastructure then establishes communication with the call center. The call center determines the identifier of an available end station and the subscriber is subsequently connected to the available end station.

  • Patent number: 6771950
    Abstract: A method and system for a wireless subscriber to initiate a calling party number trace includes receiving a Location Request Message at a Service Location Register for an inbound call to a subscriber, the message including Calling Party Information. If the subscriber has a Customer Originated Trace (COT) feature, the Calling Party Information is temporarily stored in a database. A Mobile Switching Center receives a feature code corresponding to a subscriber COT request and generates a Feature Request message. If it is determined that the subscriber has the COT feature and Calling Party Information temporarily stored in the database, the Calling Party Information is permanently stored for later retrieval.

  • Patent number: 6763103
    Abstract: The invention refers to a method and an arrangement for netwide call trace with various interfaces and protocol stacks of at least one call within a telecommunication network by using a central call trace server (CS) and local intelligent call trace intelligent agents (IA) between the switching points (SP) of the telecommunication network, said central call trace server being connected with all of said local intelligent call trace intelligent agents IA. The central server manages the intelligent agents and distributes information between the intelligent agents. Only a reduced set of necessary data are sent to the central server by the intelligent agents, in case that the central server requires more data this data are sent by the intelligent agents upon request of the central server. The method and the arrangement allows an exact call trace inclusive of wild cards and calls between different telephone networks (mobile/land).

  • Patent number: 6731733
    Abstract: A system and method to protect a target telephone number from unauthorized access includes a first one-way encoding unit to encode the target telephone number using nonreversible encoding. A storage unit stores the encoded target telephone number. A second one-way encoding unit encodes a calling telephone number and a receiving telephone number using the non-reversible encoding. A comparing unit determines whether the stored encoded target telephone number matches the encoded calling telephone number and/or the receiving telephone number and routing a call between the calling telephone number and the receiving telephone number matching the target telephone number to a monitoring unit. The monitoring unit monitors and/or records the call and connects the calling telephone number to the receiving telephone number.
