A test instrument connectable to a network to provide copper impairment testing and remediation in a digital subscriber line (DSL) service is provided. The test instrument may comprise a port connectable to a test point in a network. The test instrument may also comprise a processing circuit to perform tests in the following categories: (i) shorts, grounds, and opens, (ii) true length, (iii) balance, and (iv) series fault, wherein the combination of these tests may determine copper impairment. Once tests are conducted, one or more remediation recommendations may be provided based at least in part on failure in one of the test categories. The test results and remediation recommendations may then be presented at an output, such as a display at a test instrument or user device.

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.).

Embodiments provide systems and methods for reconstructing a communication session upon a failure of a session manager by monitoring a communication session associated with a Universal Call IDentifier (UCID) and detecting a failure of the session manager. In some cases, A timer can be set in response to detecting the failure of the session manager. In response to the timer expiring before detecting the recovery of the session manager, the application server can end monitoring of the communication session. In response to detecting a subsequent recovery of the session manager, a re-invitation message associated with the communication session and including the UCID can be sent. Communications components of the contact center can receive and accept the re-invitation message, re-map a session initiated by the re-invitation message to the communication session based on the UCID from the re-invitation message, and reconstruct the communication session.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for evaluating the quality of a communication session. One of the methods includes identifying, by a communication system, a communication session between one or more users of the communication system, wherein, during the communication session, session data is routed between a first communications device of a first user of the communication system and one or more other communications devices along a communication path; obtaining, from each of a plurality of communication nodes along the communication path, quality data relating to a quality of the communication session at the communication node; generating, using the quality data, a model input to a quality score machine learning model; and providing the model input as input to the quality score machine learning model to generate the estimated quality score for at least the portion of the communication session.

A method and device, e.g. a headset, for notifying a user of a mute state of a primary microphone during a call, in case the user speaks while the primary microphone is muted. The method comprises performing a noise cancellation algorithm (ENC) on output signals from the primary microphone and on output signals from an additional microphone capturing sound in the user's surroundings to suppress surrounding noise at the user location. Further processing output signals from the primary microphone according to a Voice Activity Detection (VAD) algorithm by means of a processor system while the primary microphone is muted. The VAD algorithm is used to determine if speech is present, and next it is determined if an additional condition if fulfilled. Then, finally providing a mute state notification to the user only if it is determined that speech is present and the additional condition is fulfilled.

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.

An interactive contact workflow system provides a graphical representation of a contact workflow in a graphical user interface (GUI). The system displays a first visual indicator that graphically highlights a first visual display object to indicate that a first instruction block is active. The system executes the first instruction block and outputs a first prompt via a communication interface, the communication interface to simulate a telephone communication with the interactive contact workflow system. The system receives a first response to the first prompt from a GUI element, identifies a first command to execute a second instruction block based at least in part on the first response to the first prompt, and displays a second visual indicator that graphically connects the first visual display object to a second visual display object within the GUI, the second visual display object corresponding to the second instruction block of the interactive contact workflow system.

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.
