In one aspect, the present invention facilitates the investigation of networks of criminals, by gathering associations between phone numbers, the names of persons reached at those phone numbers, and voice print data. In another aspect the invention automatically detects phone calls from a prison where the voiceprint of the person called matches the voiceprint of a past inmate. In another aspect the invention detects identity scams in prisons, by monitoring for known voice characteristics of likely imposters on phone calls made by prisoners. In another aspect, the invention automatically does speech-to-text conversion of phone numbers spoken within a predetermined time of detecting data indicative of a three-way call event while monitoring a phone call from a prison inmate. In another aspect, the invention automatically thwarts attempts of prison inmates to use re-dialing services. In another aspect, the invention automatically tags audio data retrieved from a database, by steganographically encoding into the audio data the identity of the official retrieving the audio data.

A method for handling calls to be moved within a system having an unmonitored domain and a monitored domain can include the step of upon first arrival of a call at said unmonitored domain, a context of said call based on a called number, a calling number, and any redirection number(s) included in said call can be provided. Another step of the method can include, for each movement of said call between said unmonitored domain and said monitored domain, providing a unique number to be temporarily used for said particular movement, based on said call context, while avoiding that said unique number is used to move any other call within the system at the same time. An apparatus for can be configured to facilitate performance of the method (e.g. communication system, a device, non-transitory memory, etc.).

A system for bi-directional quality testing of a telephony system or network using an audio generation device configured to automate Perceptual Evaluation of Speech Quality assessments and connect to a communication endpoint through computer telephony integration (CTI) instruction or system configuration to enable auto-answering of the communication endpoint, listen, record, and process signals and audio data, calculate Mean Opinion Scores (MOS), generate signals and audio for playback, compare files using a full reference algorithm, and store data with MOS results displayed in data naming structure.

This invention relates to a method of managing a digital subscriber line, where classification for a potential fault on a line is generated. The invention continuously measures the signal to noise (SNR) margin on the DSL line, and compares the measurements to predetermined conditions based on SNR margin characteristics associated with a population of good lines. Once the SNR margin measurements fail to meet the predetermined conditions, the line is flagged as experiencing a potential fault. Further measurements from weather sensors are gathered, and correlated with the SNR margin characteristics. The resulting correlation is used to generate a classification of a potential fault on the line. This can then be used to more specifically direct diagnosis and further testing.

In accordance with embodiments disclosed herein, there are provided apparatus, systems, and methods for identifying cable-level faults in a copper plant of a DSL system. For example, such means may include identifying a group of Digital Subscriber Lines (DSL lines) within a common cable; determining a baseline of physical line characteristics for each of the DSL lines in the group; collecting current physical line characteristics for each of the DSL lines in the group; determining a physical line characteristics delta for each of the DSL lines in the group by comparing the current physical line characteristics to the baseline of physical line characteristics for each of the respective DSL lines; and indicating a defect in the common cable based on a quantity of the DSL lines in the group for which the respective DSL line's physical line characteristics delta exceeds a threshold. Other related embodiments are disclosed.

Disclosed are a line diagnosis method and apparatus. The method includes: acquiring a test result reported by a test device, herein, the test result is a test result acquired after the test device tests a line that needs line diagnosis (S102); and invoking a dynamic language file to analyze the test result and obtaining a line diagnosis result, herein, the dynamic language file includes known line fault types described in a dynamic language and corresponding judging conditions (S104). Through the technical solution, the problem in the related art that the time period of re-customizing a diagnosis program for line diagnosis is too long to satisfy the user demand is solved; the time period required by function customization is largely shortened during line diagnosis, and a user can rapidly adjust the analysis solution according to changes of the line situations, the user demand is satisfied and the user satisfaction is improved.

Embodiments relate to a method for detecting a broken binder in an access network including a plurality of telecommunication lines grouped in respective binders, executed by a detection device, including identifying a plurality of telecommunication lines for which a transmission interruption has been detected within a given time period obtaining line data associated with the respective identified telecommunication lines, for respective pairs of identified telecommunication lines, determining a virtual distance between the two telecommunication lines, in function of the associated line data, determining at least one cluster of telecommunication lines in function of the virtual distances, and detecting a broken binder in function of the determined at least one cluster.

Providing high availability multi-way conferencing. Separate signaling and media components may be provided within an MCU or among a cluster of MCUs. A signaling server may control signaling aspects of a conference while a media server may provide media support for the conference. In the event of media server failure, the signaling server may assign a new media server to provide media support for the conference. A backup signaling server may also monitor the signaling server and may provide signaling support for the conference in the event of signaling server failure.

A processing device identifies comparison subjects comprising a first subject and a second subject. The processing device builds a first network of a first profile of the first subject and a second network of a second profile of the second subject, wherein the first network and the second network are multi-degree connections networks. The processing device the first network and second network to produce a similarity score. The processing device examining first-degree connections between the first network and the second network and accounting for centralities that rely on information about the first network and the second network. Responsive to the similarity score exceeding a similarity threshold, indicating the first profile and the second profile correspond to a common profile for the first subject and the second subject.
