● 'File Size' [CDRLocalMaxFileSize]: Enter the maximum size (in kilobytes) of the CDR file.
When the Current file reaches this size, the device creates a CDR file. However, if the
'Rotation Period' is reached before the file has reached this maximum size, the CDR file is
created.
● 'Number of Files' [CDRLocalMaxNumOfFiles]: Enter the maximum number of CDR files.
If this maximum is reached, any new CDR file replaces the oldest CDR file (i.e., FIFO).
● 'Rotation Period' [CDRLocalInterval]: Enter the periodic duration (in minutes) of how often
a CDR file is created from the Current file (even if empty). For example, if configured to 60,
a file is created every hour (or before, if the maximum size has been reached).
For a detailed description of each parameter, see Syslog, CDR and Debug Parameters .
3. Open the Logging Filters table (see Configuring Log Filter Rules ), and then configure a log
filtering rule with the following settings:
● 'Filter Type' and 'Value': (as desired)
● 'Log Destination': Local Storage
● 'Log Type': CDR Only
● 'Mode': Enable
If the CDR storage feature is enabled and you later change the maximum number of
files (CDRLocalMaxNumOfFiles) to a lower value (e.g., from 50 to 10), the device
stores the remaining files (e.g., 40) in its memory as
unused files.
CDR Field Description
This section describes the CDR fields that can be generated by the device. Some are generated by
default while others are generated only if you customize the CDR to include them, as described in
Customizing CDRs for SBC Calls .
■ For SBC calls, the device generates a signaling CDR and a media CDR:
● Media CDRs: This CDR is published for each active media stream, thereby allowing
multiple media CDRs, where each media CDR has a unique call ID corresponding to the
signaling CDR. There are three different CDR Report Types (CDRReportType), which are
sent to the CDR server at different stages of the SIP dialog session:
◆
"MEDIA_START": CDR is sent upon an INVITE message.
◆
"MEDIA_UPDATE": CDR is sent upon a re-INVITE message (e.g., the established
call is placed on hold by one of the call parties).
◆
"MEDIA_END": CDR is sent upon a BYE message (i.e., call ends)
The CDR Report Types for SBC media and the SIP dialog stages are shown in the
following figure:
