20130243179 | CONTACT CENTER AGENT FILTERING AND RELEVANCY RANKING - Methods and systems for supporting the monitoring and control of an automatic call distribution system are provided. In particular, a ranked list of candidate agents that can be assigned to handle contacts for a selected queue associated with an automatic call distribution system is presented to a supervisor. The supervisor can make agent assignments from the ranked list at the discretion of the supervisor. The assignment or reassignment can be effected by the supervisor through control inputs entered through the user interface. These control inputs can include reconfiguring agent and/or queue attributes. In addition, assignments can be effected through communications to agents made by the supervisor that are initiated through the user interface. | 2013-09-19 |
20130243180 | COMMUNICATION DEVICE FOR ESTABLISHING AUTOMATED CALL BACK USING QUEUES - A communication device is provided for enabling a user to establish an automated call back from a communication system, such as a call center, for example. A software device application enables the communication device to communicate with the call center through the exchange of data. The communication device includes a display screen for displaying controls for allowing the user to interact with the communication system. The controls allow the user to request a list of providers from which to select a provider or company to contact. The communication device further provides controls for allowing the user to select a queue to join from a list of queues associated with the selected provider. An embodiment may also communicate contextual data between a communication device and a communication system, including information associated with the user of the communication device and information used to assist, instruct, or solve a user's problem. | 2013-09-19 |
20130243181 | System For Presenting Scripts To A Contact - A system is disclosed for presenting a plurality of scripts to a contact. A system includes a dialer, controller, Input/Output devices, and a memory containing modules for execution on a processor. A script player module plays a plurality of prerecorded audio file scripts. A presentation module presenting a plurality of script options to an agent. An input module receives an agent input corresponding to at least one of the script options. A profile module stores a contact profile reflecting contact-specific data, and the presentation module presents script options to the agent based upon the profile for outputting contact-specific scripts. | 2013-09-19 |

20130243183 | MULTI-RECEIVING TERMINAL ECHO CANCELLATION METHOD AND SYSTEM - A multi-receiving terminal echo cancellation method and a multi-receiving terminal echo cancellation system are disclosed. The present invention performs echo filtering on receiving terminal signals in M channels by means of echo filters to obtain filtered receiving terminal signals in M channels, and subtracts the filtered receiving terminal signals in M channels from a sending terminal signal to obtain a system output signal in which receiving terminal echoes have been cancelled; and at the same time, the present invention buffers the receiving terminal signals in M channels by means of buffers, calculates a decorrelation matrix according to each of the receiving terminal signals in M channels that are buffered within preset length, decomposes the buffered receiving terminal signals in M channels into decorrelated receiving terminal signals in M channels by means of the decorrelation matrix, and calculates update amounts of the echo filters according to the decorrelation matrix, the decorrelated receiving terminal signals in M channels and the system output signal that is fed back. The technical solutions of the present invention can support the situation of two or more receiving terminals, and are suitable for situations in which the correlation between a plurality of receiving terminal signals is variable. | 2013-09-19 |
20130243184 | METHODS, APPARATUS AND ARTICLES OF MANUFACTURE TO CANCEL ECHO FOR COMMUNICATION PATHS HAVING LONG BULK DELAYS - Example methods, apparatus and articles of manufacture to cancel echo for a communication path having long bulk delays are disclosed. A disclosed example method includes determining a first location of a first coefficient having a largest magnitude of a first plurality of magnitudes associated with a first plurality of coefficients of a first phase; determining a second location of a second coefficient having a largest magnitude of a second plurality of magnitudes associated with a second plurality of coefficients of a second phase different than the first phase; comparing a difference between the first and second locations to a threshold; and, when the difference is less than the threshold, selecting a first offset based on a greater of the magnitude of the first coefficient and the magnitude of the second coefficient; and cancelling an echo contained in a signal using the first offset. | 2013-09-19 |
