First Claim
Patent Images
1. A method for monitoring a packet network, comprising:
- receiving, by a processor, a plurality of call detail records at a completion of a call from a plurality of voice gateway routers that serviced the call over the packet network;
matching, by the processor, a first call detail record of the plurality of call detail records with a second call detail record of the plurality of call detail records that were generated from the call based upon a source address and a destination address; and
monitoring, by the processor, a call performance parameter in accordance with the first call detail record and the second call detail record that are matched, wherein the call performance parameter comprises a hairpin parameter, wherein the monitoring the call performance parameter comprises determining whether the call performance parameter has exceeded a threshold value in a predetermined timeframe.

Abstract
A method and system for monitoring a packet network by using call detail records (CDRs) are disclosed. The method first receives at least one call detail record (CDR) at a completion of a call from at least one voice gateway router that serviced said call and analyzes said at least one CDR. The method then monitors at least one performance parameter in accordance with said at least one CDR.
