Abstract
After completion of a voice-over IP call, for example, first information representing a Layer 3 path of a packet flow of a completed call that has passed through a packet-switched network is created. Second information representing a Layer 2 path of a packet flow of the completed call is also created. One or more selected phone call detail records are retrieved, which are associated with the completed call. Thus, the likely path of a troubled call is determined, and phone call detail records associated with key points in the path are located. The first information, second information, and selected phone call detail records are provided to a user for use in evaluating one or more problems experienced in the completed call.
