Abstract: A system and method for providing video conferencing are described herein. Original video streams from one or more cameras are sampled to form downscaled versions of the video stream. The downscaled version is analyzed to find regions of interest and generate metadata describing aspects of the regions of interest, including a region that includes a preferred speaker and the best view of each participant present together in the video conference. Cropping instructions are generated from the metadata, and portions of the original video stream are removed to form a set of presentation views for each participant, including the preferred speaker. The set of presentation views is stitched together to form a composite display for each participant viewing the stream remotely.

Abstract: The technology described herein includes a method of receiving, by a phone, audio data from an application running on a computing system coupled to the phone; sending the audio data to an audio output device coupled with the phone; and detecting an incoming phone call to the phone and automatically handling the incoming phone call, based at least in part on one or more preferences of a user of the phone, while receiving the audio data from the application and sending the audio data to audio output device.

Abstract: A computing system and method that can be used for a video conferencing system including a watchdog to ensure that all data associated with the video conference is encrypted from end-to-end. In particular, aspects of the present disclosure provide a secure and private approach to conducting remote meetings. For example, the watchdog can monitor the data associated with the video conference, ranging from call setup data to video image and audio data transmitted from one or more client computing devices. In particular, the present disclosure provides a method for ensuring that the video conference data is protected by using multiple steps and monitoring the video conference data while the video conference is ongoing such that remedial measures can be taken immediately when a breach in security is determined.

Abstract: When an SIP server receives a call signal addressed to a callee side terminal, the SIP server transmits a warning signal to the callee side terminal before transmitting the call signal to the callee side terminal when an international call identifier indicating that the call signal passes through a foreign country is set in the call signal. In addition, when the SIP server receives the call signal addressed to the callee side terminal, the SIP server includes a warning that the caller number is disguised in a warning signal when an international call identifier indicating that the call signal passes through a foreign country is set in the call signal and the caller number of the call signal is a number from a country in which the callee side terminal is located.

Abstract: Disclosed herein are systems and methods for providing mobile call authentication. For instance, a token indicative of a call request can be received from a calling party. The token can include a called party number and a time of the request. A subscriber database can be accessed to determine identifying information associated with the calling party based at least in part on the token. The token can be authenticated based at least in part on the identifying information and using one or more predefined authentication protocols. The token can be stored in a call session registry storing data indicative of a plurality of active telephone call events. A verification request for the call request can be received from the called party. The call request can be verified based at least in part on the token. The called party can be notified that the call request has been verified.

Abstract: Methods and systems for routing multimedia traffic are described. A method may include receiving a communication originating from a user, transposing an alias transport network over one or more existing networks to route the communication, and routing the communication based on mapping rules.

Abstract: One example method includes receiving, by a video conference provider, an indication of a meeting type of a video conference; obtaining, by the video conference provider, multimedia content associated with the meeting type; receiving a request from a client device to join a main meeting of the video conference; connecting the client device to a waiting room associated with the video conference; and providing the multimedia content to the client device in the waiting room.

Abstract: A method for protecting subscriber data includes intercepting network traffic associated with a call. The network traffic includes call parameters and call stream data. A first set of the call parameters is analyzed. A first probability value of the call being declared as unwanted is determined. The call stream data is analyzed to define a second set of call parameters. The first set of call parameters is reanalyzed based on the second set. A second probability value of the call being declared as unwanted is determined. A determination is made if the second probability value exceeds a second threshold value. The call is declared as unwanted, in response to determining that the second probability value exceeds the second threshold. The first and second sets of call parameters are transmitted to an application configured to protect data of a protected subscriber.

Abstract: Automatic testing/analysis of local loops of telecommunications networks includes obtaining bits-per-tone data for a local loop of a telecommunications network and generating a bit value string from the bits-per-tone data. The bit value string is then analyzed to determine whether it includes a bit pattern indicative of an impairment of the local loop. Further approaches for automatically testing local loops of telecommunications networks include obtaining attenuation data for multiple tones carried by the local loop and determining whether the attenuation data falls below thresholds for providing a service using the local loop.

Abstract: A sequence of call volume measurements is accessed, where each of the call volume measurements is associated with respective metadata. The respective metadata may provide information regarding a time period during which a call volume measurement was made. A window of the sequence of call volume measurements with the respective metadata is input to a machine learning model to obtain a prediction of a call volume. The machine learning model includes embedding functions that are applied to the respective metadata for the call volume measurements in the window.

Abstract: Data stream based event sequence anomaly detection for mobility customer fraud analysis is presented herein. A system obtains a sequence of events comprising respective modalities of communication that correspond to a subscriber identity associated with a communication service—the sequence of events having occurred within a defined period. Based on defined classifiers representing respective fraudulent sequences of events, the system determines, via a group of machine learning models corresponding to respective machine learning processes, whether the sequence of events satisfies a defined condition with respect to likelihood of representing a fraudulent sequence of events of the respective fraudulent sequences of events. In response to the sequence of events being determined to satisfy the defined condition, the system sends, via a user interface of the system, a notification indicating that the sequence of events has been determined to represent the fraudulent sequence of events.
