Abstract: A computer program product is embodied on a computer readable medium for using voice data traffic to reproduce a user experience for facilitating troubleshooting of at least one of a plurality of VoIP stations. The computer program product includes computer-executable instructions for retrieving packets of the voice data traffic associated with the VoIP station, and identifying time stamps associated with the retrieved packets. An amount of jitter associated with each of the retrieved packets is determined at least partially dependently upon the identified time stamps, and it is determined whether each of the retrieved packets will fit into a jitter buffer at least partially dependently upon the determined amounts of jitter. The instructions include dropping select ones of the retrieved packets dependently upon the determination of whether each of the retrieved packets will fit into the jitter buffer and, filling a buffer with at least select ones of the retrieved data packets not dropped.

Abstract: A computer program product being embodied on a computer readable medium for facilitating troubleshooting a VoIP session associated with at least one VoIP station using network traffic data, the computer program product including computer-executable instructions for: identifying data packets of the network traffic data indicative of VoIP signaling information or voice communications; determining if the identified packets are associated with the at least one VoIP station; determining whether a quality of the VoIP session was acceptable substantially simultaneously with the VoIP session; and, at least temporarily storing at least a portion of the identified packets determined to be associated with the at least one VoIP station when the VoIP session is determined to of an unacceptable quality.

Abstract: Method and Apparatus for Network Problem Segment Isolation. The present invention provides a method for characterizing network segment quality for a segment transmitting messages from a first endpoint to a second endpoint on a network. The method includes the step of receiving messages transmitted between the first and second endpoints. The messages include a first set of quality metrics for message transmission from the first to second endpoint for both the first and second segments and a second set of quality metrics for message transmission from the first endpoint to the juncture. Furthermore, the method includes subtracting the second set of quality metrics from the corresponding quality metrics of the first set of quality metrics to calculate a third set of quality metrics representing the quality metrics of the second segment. Additionally, the method includes comparing the third set of quality metrics to a first set of segment qualities.
