Version 6.8 489 Mediant 2600 E-SBC
User's Manual 38. Reporting Information to External Party
38.2 Generating Call Detail Records
The Call Detail Record (CDR) contains vital statistic information on calls made from the
device. The device can be configured to generate and report CDRs for various stages of
the call, including SIP messages and/or media. You can configure when CDRs for a call
are generated, for example, only at the end of the call or only at the start and end of the
call. Once generated, the device sends the CDRs to a user-defined Syslog server.
The CDR Syslog message complies with RFC 3164 and is identified by Facility 17 (local1)
and Severity 6 (Informational).
For CDR in RADIUS format, see ''Configuring RADIUS Accounting'' on page 494.
38.2.1 Configuring CDR Reporting
The following procedure describes how to configure CDR reporting.
To configure CDR reporting:
1. Enable the Syslog feature for sending log messages generated by the device to a
collecting log message server. For more information, see ''Enabling Syslog'' on page
505.
2. Open the Advanced Parameters page (Configuration tab > VoIP menu > SIP
Definitions > Advanced Parameters). The CDR parameters appear under the 'CDR
and Debug' group, as shown below:
Figure 38-2: CDR Parameters in Advanced Parameters Page
3. Configure the parameters as required. For a description of the parameters, see
''Syslog, CDR and Debug Parameters'' on page 560.
4. (Optional) Disable the inclusion of the Sequence Number in Syslog messages, by
setting the 'CDR Session ID' parameter to Disable.
5. Click Submit.
Note:
• If you do not configure an IP address for a CDR server, the device sends CDRs to
the Syslog server, as configured in 'Enabling Syslog' on page 505.
• The device sends CDRs only for dialog-initiating INVITE messages (call start), 200
OK responses (call connect) and BYE messages (call end). If you want to enable
the generation of CDRs for non-call SIP dialogs (such as SUBSCRIBE, OPTIONS,
and REGISTER), use the EnableNonCallCdr parameter.
