According to one embodiment, a telephone number research device researches on the usage status of a telephone number in an IMS network, an NGN network, and an IP network without ringing an incoming call by transmitting a specific SIP message that causes call rejection using an IMS interconnection interface or the like for interconnection between carriers. The telephone number research device is connected via an NGN network to a telephone connected to a destination network that is an IMS network or a VoIP network. The telephone number research device adds a first SDP parameter to an INVITE request for the telephone before sending the request to the destination network selected by the NGN network and determines the usage status of the telephone number of the telephone based on a response from the destination network regardless of the type of the destination network.

In some implementations, a device may obtain data indicating a client activity, and may determine predictive level scores corresponding to predictive level options associated with the client activity. The device may transmit, to a client device, a selected predictive level option having a highest predictive level score. The device may receive, from the client device, a client query based on a rejection of the selected predictive level option, and may determine intent level scores corresponding to intent level options associated with the client query. The device may identify a selected intent level option having a highest intent level score and may initiate client experience(s) associated with the selected intent level option. The predictive level scores and/or the intent level scores may be determined based on historical training data associated with combinations of client activities, predictive level options, client queries, intent level options, client experiences, and associated success scores.

A user experience workflow may be configured based on input received for various object types selectively arranged within the user experience workflow and then bound to a destination identifier, such as a telephone number or web address. A user interface of software for configuring a user experience workflow is presented at a user device and input from that user device is used to selectively arrange objects within a user experience workflow and/or to configure objects thereof. After configurations are applied to the objects, the user experience workflow is bound to the destination identifier. An end user device which accesses the destination identifier (e.g., by calling the telephone number, visiting the web address, or using an application connecting to the web address) may then traverse the user experience workflow, including in some cases having configured content presented thereto.

A system for assigning reputation scores is provided. The system includes a first database, a second database, and a registrar server. The first database stores first data corresponding to at least one telecommunications identifier. The second database stores second data corresponding to the at least one telecommunications identifier. The registrar server is structured to: access and interpret the first data and the second data to determine one or more attributes for the at least one telecommunications identifier; determine a reputation score for the at least one telecommunications identifier; and transmit the reputation score.

A method and system are disclosed for determining the geographic location of a user communicating on a communications network such as the Internet. In one embodiment, a provider of a product or service: (a) receives the user's phone number (or other identification for contacting the user's station), and (b) supplies the user's station with a distinctive identifier. The provider then supplies a location determining service with the user's phone number (or other identification). A phone call is made to the phone number by the location determining service for retrieving the distinctive identifier from the network station having the phone number. If the distinctive identifier is retrieved and the location determining service determines that the user's station is within an appropriate geographical area (or not within an inappropriate area), then the provider can provide the requested product or service to the user.

A number management unit (11) of a number management system (1) generates a transaction to be managed in a blockchain based on number portability information obtained by receiving a number update request, generates a block obtained by aggregating multiple transactions, approves a suggested block by confirming normality of the block, and stores the block by connecting the block to a blockchain in a number database (13). If a reset of the block in the number database (13) is suggested, the number management unit (11) transmits, to multiple number management apparatuses (10), a reset suggestion block including, as a transaction, a reset suggestion, which is information indicating a suggestion for a reset, and if the reset suggestion block is approved, the number management unit (11) discards the blockchain in the number database (13).

Device, method, medium and computer program product for voice data transmission. The device includes a processor that executes instructions in memory to: establish a call connection for voice data transmission with another device, wherein the said device parses and identifies the number of the said another device to determine whether the voice data transmission is associated with an international call, and when the voice data transmission is determined to be associated with an international call, the determine hop limit value for the voice data transmission as a first value greater than the default hop limit value; or when the voice data transmission is determined to not be associated with an international call, the hop limit value for the voice data transmission is determined as the default value; and generate packets for sending voice data based on the hop limit value determined when the call connection is established.

Voice communication network defense security which allows for managing and/or preventing voice calls based on which telecommunication carrier provided the calling number. By managing calls based on telecommunication carrier as opposed to the calling number, the present invention seeks to prevent intrusion by wrongdoers who may otherwise be in possession with an unlimited supply of calling numbers. Further, by implementing the security measures at the voice communication network perimeter, voice calls can be managed and/or prevented/block in real-time while the call is in a pre-answer state. As a result, the present invention provides the capability to prevent/block wrongdoers from accessing the intra-voice communication network or, at a minimum ensures that potential wrongdoers are properly vetted through an investigative process.

A telecommunications addressing system/method allowing selection of a telephone instrument device (TID) using arbitrary identifiers is disclosed. The system/method allows a source TID (STD) to select a target TID (TTD) by the use of a Target Telephone Identifier (TTI) data string rather than a traditional numeric telephone identification (NTI). This TTI is then indexed within a TTI/NTI mapping server (TMS) that functions as a hierarchical repository of TTI/NTI mappings. STD/TTD communication is established by first performing a lookup of the STD-selected TTI within the TMS to identify the NTI of the TTD. Once the NTI of the STD has been identified by the TMS, communication between the STD and TTD is established using the NTI via the normal public switched telephone network (PSTN). TMS TTI lookup may be performed via STD TID web application and/or via PSTN infrastructure interface.

Telecommunications systems and methods having a mapping server; a communication network; and a mapping database in communication with the mapping server via the communication network, the mapping database associating telephone identifier data strings (which identify a target telephone device) with numeric telephone identifiers; the mapping server is configured to match numeric telephone identifiers of a source telephone of a caller and a target telephone of a callee with respective telephone identifier data strings using the mapping database; the mapping sever is configured to initiate an electronic communication between the source telephone and the target telephone; the numeric telephone identifier of the target telephone is masked to the caller using the target telephone identifier; the mapping server is configured to locate the target telephone device by the telephone identifier data string to provide a Global Positioning System display of the target telephone device on a screen of a source telephone device.
