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.
