26.1 Overview

This chapter shows you how to collect and manage Call Detail Records (CDRs) on the X2002.
Call Detail Records (CDRs) are telephone records containing details such as the time of call,
duration of call, source telephone number and so on. The X2002 has a built in CDR database
that automatically stores calls made to or from its extensions. You can search the CDR
database to find out details about your organization's calls. You can also use an external
database to store CDRs.

26.1.1 What You Can Do in the CDR Screen

• Use the Management screen to configure where to store CDR information, an
administrator e-mail address to send alerts and CDR backup files for later viewing
(Section 26.2 on page
• Use the Backup List screen to manage CDR backup files
• Use the CDR Query screen to query and create CDR reports

26.1.2 What You Need to Know About CDR

The following terms and concepts may help as you read through this chapter.
Local CDR Database
The local CDR database has limited capacity and when it is full it empties its contents into a
compressed file of the call records. This file is referred to as an "Aged File". You can delete an
"Aged File" or forward it to an e-mail address where it can be reviewed at a later time. The
CDR database is then emptied. Whether you delete the aged file or send to an administrator,
the X2002 continues to record telephone call details in an empty CDR database.
Another way to deal with the limited capacity on the local CDR database of the X2002 is to
actively manage the CDR database. This requires you to create backups of the CDR database
and send them to an administrator via e-mail.
Viewing Aged Files
An "Aged File" is a compressed file with the extension ".tgz". ".tgz" files can be
decompressed with data compression utilities for example WinRAR or WinZIP. The result of
decompressing this file are three files which can then be managed via a MySQL Database
Management System (DBMS). The three files are:
• cdr.MYD - a MySQL data file.
