A call detail record may be generated for the peering partner, which may include a market value of call traffic, a variable cost of the call traffic, and a determined compensation amount. The market value is based on revenue for terminations of the call traffic from the peering grid, the variable cost is a function of sharing the market value between the peering grid and the peering partner, and the compensation amount due is a function of the variable cost. | 2011-12-08 |
20110299674 | Method and Apparatus for Wideband Conferencing - A method and apparatus for wideband voice and optional data conferencing over a telecommunications network channel between at least two wideband communications devices. An exemplary method comprises establishing an audio link, verifying wideband capability between the at least two wideband communications devices, training modems of the at least two wideband communications device to line conditions, and adjusting the telecommunications connection line conditions between the communications devices. Once a wideband connection has been established, audio and data may be simultaneously exchanged. | 2011-12-08 |
20110299675 | SAFE CONVERSATION PARK AND RETRIEVAL - Safe parking and retrieval of multimodal conversations is enabled through a park server generating a token and encoding it in an address identifier associated with a parking slot. A client application can display the address identifier with the token as a link in a text-based message or in conversation history items. The identifier encoded link may ensure that the intended call can be retrieved from a given parking slot without being confused with another parked call. If another call is parked at the same orbit, the encoded token does not match, and the park server may reject the retrieval attempt with an error message. | 2011-12-08 |
20110299676 | CUSTOMER CARE SUPPORT SYSTEM WITH CALL AVOIDANCE PROCESSING - Methods and systems for managing customer activity in a call center include monitoring event data. A mediator filters the event data into an event data set associated with a selected customer. A context component creates a context for the customer based on the event data set. A decision engine performs a probabilistic assessment of an occurrence related to the customer, based on the customer context, and determines an action based on the probabilistic assessment. An action processor initiates the action. | 2011-12-08 |
20110299677 | CALL SIGNAL GENERATING DEVICE - A call signal generating device, whose pair of output terminals is connected to a telephone set, includes a rectifier rectifying an inputted high frequency signal and maintaining an output polarity in one of two polarities ; and a polarity reverser generating a call signal by periodically reversing the output polarity of the rectifier and supplying it to the telephone set via the pair of output terminals. | 2011-12-08 |
20110299678 | SECURE MEANS FOR GENERATING A SPECIFIC KEY FROM UNRELATED PARAMETERS - A technique and method for improving the security of the usage of a key in devices or systems with modes of operation that must be secured whereby the key has multiple fields with timing information that must be matched to transitions of a randomly generated clock, the randomly generated clock derived from a fixed frequency clock, whereby tampering of the fixed frequency clock will result in detection of the security attack and exit from the secure mode of operation. | 2011-12-08 |
