Abstract: The invention presents a method of identifying faults on a DSL line, typically intermittent faults arising from unstable joints in the DSL line. The method collects errored seconds data at the DSLAM and at the customer's premises equipment (CPE, typically a home hub or router). The error data collected at the DSLAM are termed near-end errors, and the error data collected at the CPE are termed far-end errors. The near-end and far-end data is then analyzed by applying regression analysis to determine if there is a correlation or match between the two sets of data. Matching data patterns are indicative of unstable or bad joints in the DSL line, and are typically intermittent and located near the customer's premises.

Abstract: A method describes enriching a Call Detail Record (CDR) to identify traffic routing through network providers. The method comprises the steps of obtaining Operator Carrier Numbers (OCNs) assigned to network providers operating in a network; obtaining trunk group identifiers for identifying trunks configured to interconnect an Originating Provider's network including a Mobile Switching Center (MSC) with network providers; and identifying network providers configured to communicate through the trunk groups with the Originating Provider's network, including the MSC. The method also obtains a Called Party Number (CdPN) from the CDR; and associates the CdPN with an OCN of a network provider. The method also determines whether the OCN associated with the trunk group and the OCN of the CdPN are the same.

Abstract: A new audio echo cancellation (AEC) approach is disclosed. To facilitate echo cancellation, the method adjusts for errors (called drift) in sampling rates for both capturing audio and playing audio. This ensures that the AEC module receives both the signals at precisely the same sampling frequency. Furthermore, the far-end signal and near-end mixed signal are time aligned to ensure that the alignment is suitable for application of AEC techniques. An additional enhancement to reduce errors utilizes a concept of native frequency. A by-product of drift compensation allows for excellent buffer control for capture/playback and buffer overflow/underflow errors from drift errors are eliminated.

Abstract: Data signals (e.g DTMF tones) transmitted on a telephone call between a customer terminal (1) and a call center platform (4) are diverted at the call center platform 4 to a secure payment system (3) such that the call center operative cannot intercept them. In order to verify that this has been done, the security system provides access to the user over a connection (23,230) independant of the connection (34,41) to the call center that allows the user to independently verify that the secure connection 34 has been made. This may take the form of returning the user's calling line identity (CLI) for the connection (34) over the independant connection (23/230) or, where CLI is not available, transmitting a one-time code over one of the links for the user to return over the other. The customer can continue to talk to the call center operative as only DTMF tones are diverted.

Abstract: An indication of an incoming call may be received at a call control unit communicatively coupled to, and/or resident within, a telephone. The indication may include identification information for the incoming call. It may be determined whether additional information regarding a caller associated with the identification information exists, and if so, a first operation may be performed on the incoming call responsively to the additional information, otherwise, a second operation may be performed on the incoming call responsively to an absence of the additional information. The additional information my include a user-configurable list of desired callers (e.g., a whitelist) and/or undesired callers (e.g., a blacklist). The additional information may also include caller identification information and/or a spam score.

Abstract: Local call information data sets are obtained for each of a plurality of devices engaged in a call, the local call information data sets comprising call attributes and associated metadata. Call signaling is mapped by correlating at least one attribute pertaining to the call in each of the local call information data sets. Global end-to-end call state machine is generated subsequent to mapping of call signaling. The global end-to-end call state machine includes a plurality of global states. Each global state represents a local state of each device along with state transition indicating change in the local state of at least one device.

Abstract: Proposed is an improved method of determining the location of a common fault on a line in a telecommunications network. An overall performance measure is generated for each of the lines in the network based on various electrical measurements, highlighting potentially faulty lines. Nodes within the network also have a performance measure calculated based on the performance measures of the lines passing through the node. Examples of nodes include cross connection points, junction boxes, cabinets, and sections of cabling. A common faulty node is identified from all nodes along a line, based on the overall performance measures associated with those nodes. Then, all other faulty lines running through that node are identified. A distance to fault measurement is estimated for each of the identified faulty lines, using capacitance measurements for each line. A common fault location is determined based on aggregating the estimated distances to fault calculated for each of the identified faulty lines.

Abstract: Systems and approaches are provided to allow for rendered audiovisual communication. An electronic device can be used to capture image information relating to physical features of a user. A model can be generated from the image information, and the model may be used to render audiovisual communication information from image and audio captured in real time. The rendered audiovisual communication data can simulate live video conferencing with substantial performance gains over conventional approaches to video conferencing. When the image capturing component of the electronic device is capable of depth imaging, stereo imaging, or other imaging techniques, the rendered audiovisual communication can be further enhanced with 3-D rendering of the user. Other aspects of audiovisual data, such as speech, background, and lighting conditions can also be rendered or synthesized to improve audiovisual communication.

Abstract: Various embodiments of the invention provide methods, systems, and computer program products for handling an audio path failure and/or non-conformant QoS for a call between a contact center agent and remote party. Specifically, an audio path is established to a first telephony device being used by the agent and a call is bridged onto the audio path so that audio can be streamed back-and-forth between the first telephony device and a second telephony device being used by the party. Accordingly, various embodiments of the invention involve monitoring the audio path to detect an audio path failure and/or non-conformant QoS for the audio and bridging the call onto a second audio path when a failure or non-conformant QoS is detected so that the call is not disconnected from the second telephony device and a third device (e.g., IVR) can stream audio over the second audio path to the second telephony device.

Abstract: In order to detect a specific codec sequence being used, a signal that is based on a codec sequence is analyzed. The signal is analyzed to determine if there is a pattern in the signal. A pattern of a codec sequence can be a unique pattern of frames, frequencies and/or frequency ranges that are generated based on a specific codec sequence. The pattern is compared to one or more previously stored patterns of codec sequences to see if there is a match. If there is a match, an event is generated. For example, if a known codec sequence that has a poor signal quality is determined to be in use for a voice call, the parties may be notified that the call is likely to be a low quality voice call.
