  • Patent number: 9020123
    Abstract: A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to obtain billing data associated with a plurality of calls over a Voice Over Internet Protocol network, determine special service calls being made based on the billing data, monitor for the special service calls being associated with at least one of one calling number or one network node, and determine an undesired condition based at least in part on the special service calls being made from the one calling number or through the one network node exceeding a threshold. Other embodiments are disclosed.

  • Patent number: 8976783
    Abstract: In one embodiment, the present invention is a method and apparatus for assuring Voice over Internet Protocol service. In one embodiment, a system for assuring Voice over Internet Protocol service includes a performance management platform for collecting performance management data from a plurality of sources in a Voice over Internet Protocol network, for detecting at least one abnormal event in accordance with the collected performance management data, and for reporting a volume of traffic in the Voice over Internet Protocol network and a trouble ticketing system for generating a ticket identifying a root cause of the abnormal event(s).

  • Patent number: 8792482
    Abstract: In one embodiment, a method for managing a Voice over IP (VoIP) network includes collecting a first set of data from a first source of network performance management data, each data item in the first set of data corresponding to a call made using the VoIP network; collecting a second set of data from a second source of network performance management data, each data item in the second set of data corresponding to a call made using the VoIP network and being of a different type than the first set of data; correlating the first set of data and the second set of data such that a data item from the first set of data is matched with a data item from the second set of data that corresponds to a common call made over the VoIP network; and outputting a performance report based on the correlating.

  • Patent number: 8755499
    Abstract: Methods, computer program products, and systems for managing VoIP network elements are provided. Methods include receiving call details records (CDRs) from a plurality of network elements. The received CDRs including disconnect cause codes and telephone call correlation identifiers. The received CDRs are correlated to telephone calls based on the telephone call correlation identifiers. Two CDR records are associated with the same telephone call when their telephone call correlation identifiers are the same. A master correlated CDR is created for each telephone call. The creating includes assigning a correlated disconnect cause code and classifying the telephone call. The assigning and classifying are responsive to the received CDRs associated with the telephone call. The master correlated CDR includes the correlated disconnect cause code and the telephone call classification. A threshold crossing alert (TCA) is generated in response to a threshold for the correlated disconnect cause code being reached.

  • Patent number: 8634527
    Abstract: A method and apparatus that employ the use of CDRs to effectively monitor and proactively respond to network or service events that impact performance within a network are disclosed. For example, the method receives a plurality of call detail records (CDRs), wherein each of the plurality of call detail records comprises a plurality of fields. The method determines a n-field rule signature from each of the call detail records (CDRs), and analyzes the n-field rule signatures from the plurality of call detail records (CDRs) for detecting at least one network performance problem.

  • Patent number: 8625409
    Abstract: A method and apparatus for correlating and suppressing performance alerts in a packet network are disclosed. In one embodiment, a method for handling alerts in a packet network includes receiving a plurality of alerts relating to one or more faults in the packet network, wherein the plurality of alerts is generated from information contained in a plurality of call detail records, correlating the plurality of alerts into one or more sets of performance alerts, each of the one or more sets of performance alerts being associated with a common one of the one or more faults, and suppressing at least one further alert relating to at least one of the one or more sets.

  • Patent number: 8576724
    Abstract: Special service impacting events in an IP network are collected and correlated. Real-time data representing occurrence of trunk group events impacting special services in trunk groups that are in service is collected, along with call detail records recorded by network elements representing occurrence of call events impacting special services and performance measurements of network elements representing occurrence of events affecting performance of the network elements impacting the special services. The collected real-time data representing occurrence of trunk group events, collected call detail record and collected performance measurements are correlated, and alarms are generated based on the correlated data.
