Call Intelligence System Detects Remote Call Redirection Arbitrage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In detention facilities, the increased security measures for inmate calls lead to higher operating costs and revenue loss due to remote call forwarding services that arbitrage lower rates, compromising security and revenue visibility.
Innovation Solution
Implementing call intelligence systems that detect remote call redirection by analyzing various information points, such as billing details and geographic locations, to determine the risk of arbitrage and apply appropriate call treatment measures, including blocking or recording calls, to maintain security and revenue integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If remote call forwarding services are used to arbitrage lower rates, then operating costs are reduced, but security measures are compromised and revenue visibility is lost
Solution Approach 1:
The system performs preliminary detection of remote call forwarding by analyzing call setup messages and comparing called party numbers with forwarding destination numbers before the call is completed. This allows the system to identify arbitrage attempts in advance and apply appropriate call treatment measures to prevent security compromises and revenue loss.
Solution Approach 2:
The system establishes feedback loops by monitoring call patterns, detecting anomalies indicative of remote call forwarding, and automatically responding with call treatment actions. The system continuously analyzes billing information, geographic location data, and call detail records to provide real-time feedback on potential arbitrage activities and adjust security measures accordingly.
2Loss of energy
If remote call forwarding services are used to arbitrage lower rates, then operating costs are reduced, but revenue integrity is lost
Solution Approach 1:
The system performs preliminary analysis of call routing information by comparing the called party number with the forwarding destination number extracted from call setup messages. This early detection mechanism identifies arbitrage attempts before they impact revenue, allowing the system to maintain accurate billing records and revenue visibility while preventing operating cost reductions through fraud.
Solution Approach 2:
The system implements continuous feedback monitoring of call detail records, billing information, and geographic location data to detect patterns consistent with remote call forwarding arbitrage. This feedback mechanism ensures revenue integrity by automatically identifying and flagging suspicious calls for further analysis or blocking.
3Reliability
If call intelligence systems implement detection and treatment measures, then security and revenue integrity are maintained, but device complexity increases
Solution Approach 1:
The system segments the call detection and treatment process into distinct functional modules: call setup message analysis, number comparison logic, risk assessment algorithms, and call treatment execution. Each module handles a specific aspect of the detection process, making the overall complex system more manageable and maintainable while preserving security effectiveness.
Solution Approach 2:
The system introduces an intermediary call intelligence layer between the telecommunication network and the billing system. This intermediary analyzes call setup messages, compares routing information, and determines appropriate call treatment without requiring fundamental changes to existing network infrastructure, thereby maintaining security while limiting the increase in overall system complexity.
4Loss of information
If call intelligence systems implement detection and treatment measures, then revenue integrity is maintained, but device complexity increases
Solution Approach 1:
The system segments revenue protection functions into separate analytical modules that process call detail records, billing information, and geographic location data independently. This modular approach maintains comprehensive revenue visibility while making the complex detection system easier to implement and maintain by dividing it into manageable functional units.
Solution Approach 2:
The call intelligence system acts as an intermediary layer between existing telecommunication infrastructure and billing systems. It provides advanced revenue protection capabilities through intelligent analysis without requiring complex integration with legacy systems, thereby maintaining revenue integrity while minimizing the increase in overall system complexity.

AI summary
Systems and methods in which call intelligence, such as may be deployed in communication with signaling systems utilized in controlling calls and telecommunication databases, is used to analyze information about a call in order to make a determination as to the likelihood or risk that call redirecting, such as call forwarding or remote call forwarding, will be invoked with respect to a call are shown. The call intelligence, upon a determination that an unacceptable risk that call redirecting will be invoked, preferably institutes appropriate call treatment or handling procedures, such as to block the call or to allow the call while invoking additional call treatment action.
