Abstract:
1. A method for managing a voice over internet protocol network, comprising: collecting, by a processor, a set of call detail record data, each of a plurality of data items in the set of call detail record data corresponding to a call detail record made using a call detail recording function of the voice over internet protocol network; collecting, by the processor, a set of session initiation protocol signaling message data from multiple calls between a plurality of nodes in the voice over internet protocol network, each of a plurality of data items in the set of session initiation protocol signaling message data corresponding to a call signaling data of a plurality of calls made using a signaling function of the voice over internet protocol network, wherein the set of session initiation protocol signaling message data comprises session initiation protocol signaling message data for defect calls only; correlating, by the processor, the set of call detail record data and the set of session initiation protocol signaling message data such that a data item from the set of call detail record data is matched with a data item from the set of session initiation protocol signaling message data that corresponds to a common call made over the voice over internet protocol network; and outputting, by the processor, a performance report based on the correlating.
