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

3. Call Accounting Systems… Capture information about telephone calls from the system's Station Message Detail Reporting (SMDR) port Capture information about telephone calls from the system's Station Message Detail Reporting (SMDR) port Record and analyze the data Record and analyze the data Prepare reports on the data Prepare reports on the data

4. What information is in the report? Which extension originated a call Which extension originated a call Number dialed (local or long distance) Number dialed (local or long distance) Circuit that was used for the call (WATS, MCI, etc.) Circuit that was used for the call (WATS, MCI, etc.) When the call started When the call started How long it lasted How long it lasted Account code (sometimes) identifies why call was made Account code (sometimes) identifies why call was made

5. How is data collected? Two primary methods are used: Two primary methods are used: A data-buffer device is connected to the SMDR port via a serial cable. "Remote-pollable" buffer devices contain a modem, which is directly connected to a trunk or inside analog line. At regular intervals, the buffer may initiate a call or receive one from a computer at a central location and deliver its load of call data.

At regular intervals, the buffer may initiate a call or receive one from a computer at a central location and deliver its load of call data. A standalone computer system running call accounting software is attached directly to the SMDR port. Records are stored to hard disk immediately. Analysis and reporting proceeds from the console, or through workstations attached to the main system over the network.

The information can be used to: Allocate calling costs among departments Allocate calling costs among departments Billing clients for tolls Billing clients for tolls Sharing and resale of long distance and local calls Sharing and resale of long distance and local calls Motivating salespeople (call volume) Motivating salespeople (call volume) Personnel evaluation (phone productivity) Personnel evaluation (phone productivity) Controlling abuse Controlling abuse Long distance bill verification Long distance bill verification Network optimization Network optimization Phony system diagnostics Phony system diagnostics Tracing calls Tracing calls
