Abstract: A system and method that allocate call capacity based on the need to divide the call capacities of at least some call-termination devices across geographic regions. Accordingly, the allocation system uses various input parameters as constraints in a linear programming optimization, which has the objective of maximizing the capacity allocation of a device to fulfill the traffic demands of each region being processed. The input parameters that are used include i) the traffic demand forecast of each geographic region being evaluated, ii) the available call capacity of each call-termination device, iii) the call destinations associated with each region, and iv) service levels associated with each given call destination. Call-capacities are separately allocated for i) the predicted traffic that is expected in the next time period and ii) an additional margin of excess traffic above and beyond the expected traffic.

Abstract: A video session manager and method for enabling, optimizing and managing inter-domain video calling, telepresence and videoconferencing sessions, in exclusive video sessions, or within multi-modal communications sessions. The video session manager and method is operative for receiving and analyzing a communications session request from one or more endpoints (users); determining the viability of a communication session based on one or more attributes of the session; connecting the one or more requesting endpoints to start the session; continuously or periodically monitoring the session for problems with or changes in the session; and altering the parameters of the session in accordance with one or more predetermined policies, if a problem or change is detected, in order to maintain the viability of the session.
Abstract: A method in support of wireless roaming comprising filtering selected mobile subscriber data for a mobile subscriber based on data exchange packages that are established pursuant to bilateral records exchange agreements, transmitting the filtered data to a wireless networks that provides broadband roaming service to the mobile subscriber, receiving information from a visited network about the mobile subscriber's activity therein, and settling charges between wireless networks that provided service to the subscriber.
Abstract: A system and method blend particular quality considerations into the process of expanding the route choices in a route table, such that more calls can be successfully routed while maximizing certain objectives. The quality considerations drive how additional routes are chosen for the route table and how call volumes are allocated to the chosen routes so that overall profitability can be maximized within the governing constraints of quality targets, route quality, predicted traffic, and route capacity.

Abstract: A records exchange system and method comprises a data processing system that receives selected mobile subscriber data for mobile subscribers, filters the data based on data exchange packages that are established pursuant to agreements with third parties, and transmits the filtered data to the third parties.
Abstract: Fraudulent VoIP calls are detected and blocked by automated procedures performed at a router server in the VoIP service provider's system which, usually, just analyzes call requests and sets up a route between the calling and called parties. The stringency of automated fraudulent call detection and blocking processes is based on calling customer credit worthiness and the destination of the call.
