1. A method for handling Voice over Internet Protocol (VOIP) traffic flows on a computer network, the method comprising:
collecting traffic flow data with respect to an IP session;
collecting parameters associated with the IP session, where in the parameters comprise traffic flow bitmaps;
determining whether the IP session is a VoIP session;
correlating IP sessions having similar parameters to the collected parameters of the VOIP session based at least in part on the traffic flow bitmaps and on network latency and packet loss; and
creating at least one Internet Protocol Detail Record (IPDR) or Call Detail Record (CDR) based on the correlated IP session parameters.
