Abstract: Methods, systems, and computer program products for selecting or generating a single call detail record (CDR) from a plurality of CDRs associated with a call that includes a plurality of legs are disclosed. According to one aspect, a CDR selection/consolidation function may analyze CDRs for calls that involve a plurality of legs and select a representative CDR for the call. The selected CDR is provided to a network services application. According to another aspect, the CDR selection/consolidation function may locate a plurality of CDRs associated with a multi-leg call and produce a single consolidated or “blended” CDR that is representative of the call. The consolidated CDR may contain information from some or all of the multiple CDRs.

Abstract: Methods and systems for generating accurate call detail records in networks that utilize number portability are disclosed. A number portability reconciliation (NPR) monitoring system receives signaling messages relating to different calls or transactions. The signaling messages may be copied from a network monitoring location upstream from where a number portability database lookup occurs for a call. The monitoring system automatically correlates messages relating to the same call or transaction into a call detail record usable by a plurality of different network monitoring applications. The NPR monitoring system determines whether number portability processing is required, and, in response, the NPR monitoring system queries a number portability database. The NPR monitoring system receives a response from the number portability database and updates the call detail record based on the response.

Abstract: Methods and systems for detecting and mitigating call routing arbitrage in a telecommunications network are disclosed. A network routing node, such as a signaling gateway (SG), intercepts call setup signaling messages. An arbitrage detector/processor examines parameters contained in an intercepted message to identify the presence of call routing arbitrage. For messages that indicate the presence of call routing arbitrage, the arbitrage detector/processor may perform a mitigating action, including redirecting the call to an interactive voice response (IVR) node, blocking the call, and/or inserting missing information in the call setup message and completing the call.

Abstract: Methods and systems for identifying calls connected without answer supervision and for automatically generating billing information for these calls are disclosed. A monitoring device copies signaling messages associated with calls. The signaling messages are correlated into call detail records. The call detail records are analyzed to identify calls connected without answer supervision. In one implementation, calls that exceed a predetermined duration and for which no answer message was returned from the terminating end office are identified as calls without answer supervision. For these calls, billing records may be generated and forwarded to a network billing center.

Abstract: A method of routing a call including a called number in a communications network such as a Public Switched Telephone Network (PSTN), the method including determining if the called number is a network routing number indicating a specific switching node and line associated therewith in the communications network and routing the call within the communications network based on the called number when the called number is a network routing number. Additionally, the method includes identifying a network routing number based on the called number when the called number is not equal to the network routing number and routing the call within the communications network based on the identified network routing number.
