IntroductionIntroduction

The purpose of this project was to obtain The purpose of this project was to obtain and analyze an SMDR from a PBX and and analyze an SMDR from a PBX and look for possible toll abuse. In the look for possible toll abuse. In the following presentation, we will describe following presentation, we will describe what a Call Accounting System is, and what a Call Accounting System is, and how it benefits an organization. We will how it benefits an organization. We will also look into the different types of reports also look into the different types of reports which may be generated from a Call which may be generated from a Call Accounting System.Accounting System.
