Customizing CDRs for SBC Calls and Test Calls

The SBC CDR Format table lets you customize CDRs for SBC calls and CDRs for Test Calls that are generated by the device for the following CDR types:

■ CDRs for SIP signaling or media sent in Syslog messages. For CDRs sent in Syslog messages, you can customize the name of the CDR field. You can configure up to 128 Syslog CDR customization rules.
■ CDRs for RADIUS accounting and sent in RADIUS accounting request messages. For RADIUS accounting CDRs, you can customize the RADIUS Attribute's prefix name and RADIUS Attribute's ID, for standard RADIUS Attributes and vendor-specific RADIUS Attributes (VSA). For example, instead of the default VSA name "h323-connect-time" with RADIUS Attribute ID 28, you can change the name to "Call-Connect-Time" with ID 29. You can configure up to 70 RADIUS-Accounting CDR customization rules (i.e., maximum number of RADIUS Attributes that the device can include in the CDR). For more information on RADIUS accounting, see Configuring RADIUS Accounting.
■ CDRs stored locally on the device. For local storage of CDRs, you can customize the name of the CDR field. You can configure up to 64 locally-stored CDR customization rules. For more information on storing CDRs on the device, see Storing CDRs on the Device.
■ CDRs (signaling only) sent to the REST server in JSON format using the device's REST API. You can configure up to 64 JSON CDR customization rules. For more information on CDRs and REST, see Configuring CDR Reporting to REST Server.

Customizing the CDR means the following:

■ Defining which CDR fields are included in the CDR. For example, if you configure only one customization rule for the Syslog signaling (SBC) CDR type with the Call Duration CDR field, the device generates these CDR types with only this single CDR field.

You can also customize the CDR to include a user-defined CDR field based on any SIP header information. This is done by using Message Manipulation rules with the call variables Var.Call.Src/Dst.<Variable Name>, where Variable Name is UserDefined1, UserDefined2, UserDefined3, UserDefined4 or UserDefined5. The Message Manipulation rule stores the SIP header value in the variable. When you customize the CDR in the SBC CDR Format table, you need to select the same variable (Var Call User Defined 1-5) in the 'CDR Field Type' parameter that you used in the Message Manipulation rule. When the device generates the CDR, it retrieves the stored information from the variable and adds it to the CDR under your customized CDR field title. If a variable is not added or modified in the Message Manipulation rule, and the CDR is customized to include its stored value, the CDR displays an empty string for the value. For an example, see Example of Call Variables for CDR Customization.

■ Changing the default name (title) of the CDR field. For example, you can change the title of the Call Duration CDR field to "Call Length".
■ Changing the RADIUS Attribute's prefix name and ID, for standard RADIUS Attributes and vendor-specific RADIUS Attributes (VSA).
● If you don't customize the CDR, the device generates the CDR in a default format (fields and titles). For a detailed description of the fields that can be included in the CDR (customized and default), see CDR Field Description.
● To return to the default CDR format for a specific CDR type, remove all the customization rules of that CDR type.
● When customizing the RADIUS CDR:
✔ The following standard RADIUS Attributes cannot be customized: 1 through 6, 18 through 20, 22, 23, 27 through 29, 32, 34 through 39, 41, 44, 52, 53, 55, 60 through 85, 88, 90, and 91.
✔ You must add the following RADIUS Attribute as the first rule in the SBC CDR Format table to ensure uniqueness (and to differentiate) between Call Connect (START) and Call End (STOP) RADIUS packets:

● If the RTCP XR feature is unavailable (not licensed or disabled), the R-factor VoIP metrics are not provided in CDRs (CDR fields, Local R Factor and Remote R Factor) generated by the device. Instead, these CDR fields are sent with the value 127, meaning that information is unavailable.
● Test Call CDRs include "CALL_START", "CALL_CONNECT" and "CALL_END" CDR Report Types.
● By default, SBC signaling CDRs that are sent at the end of the call ("CALL_END" CDR Report Type) include only signaling-related CDR fields. However, by using the SBC CDR Format table, you can customize this CDR to also include media-related fields.
● To view historical CDRs stored on the devicesee Viewing CDR History of SBC and Test Calls.

The following procedure describes how to customize SBC and Test Call CDRs through the Web interface. You can also configure it through ini file [SBCCDRFormat] or CLI (configure troubleshoot > cdr > cdr-format sbc-cdr-format).

➢ To customize SBC and Test Call CDRs:
1. Open the SBC CDR Format table (Troubleshoot menu > Troubleshoot tab > Call Detail Record folder > SBC CDR Format).
2. Click New; the following dialog box appears:

3. Configure the CDR according to the parameters described in the table below.
4. Click Apply.

Examples of configured CDR customization rules are shown below:

SBC CDR Format Table Parameter Descriptions

Parameter

Description

'Index'

[SBCCDRFormat_Index]

Defines an index number for the new table row.

Note: Each row must be configured with a unique index.

'CDR Type'

cdr-type

[SBCCDRFormat_CDRType]

Defines the application type for which you want to customize CDRs.

■ [1] Syslog SBC = (Default) Customizes CDR fields for SIP signaling-related CDRs sent in Syslog messages. However, for SBC signaling "CALL_END" CDR Report Types (sent at the end of the call), you can also customize the CDR to include media-related CDR fields (e.g., Local Packet Loss).

'Title'

title

[SBCCDRFormat_Title]

Defines a new name for the CDR field (for Syslog or local storage) or for the RADIUS Attribute prefix name (for RADIUS accounting) that you selected in the 'Column Type' parameter.

The valid value is a string of up to 31 characters. You can also configure the name to be enclosed by quotation marks (single or double). For example, if you want the CDR field name to appear as 'Phone Duration', you must configure the parameter to 'Phone Duration'. You can also configure the CDR field name with an equals (=) sign, for example "call-connect-time=".

Note:

■ For VSA's that do not require a prefix name, leave the parameter undefined.
■ The parameter's value is case-sensitive. For example, if you want the CDR field name to be Phone-Duration, you must configure the parameter to "Phone-Duration" (i.e., uppercase "P" and "D").

'RADIUS Attribute Type'

radius-type

[SBCCDRFormat_RadiusType]

Defines whether the RADIUS Attribute of the CDR field is a standard or vendor-specific attribute.

■ [0] Standard = (Default) For standard RADIUS Attributes.
■ [1] Vendor Specific = For vendor-specific RADIUS Attributes (VSA).

Note: The parameter is applicable only to RADIUS accounting (i.e., 'CDR Type' parameter configured to RADIUS SBC).

'RADIUS Attribute ID'

radius-id

[SBCCDRFormat_RadiusID]

Defines an ID for the RADIUS Attribute. For VSAs, this represents the VSA ID; for standard Attributes, this represents the Attribute ID (first byte of the Attribute).

The valid value is 0 to 255 (one byte). The default is 0.

Note:

■ The parameter is applicable only to RADIUS accounting (i.e., 'CDR Type' parameter configured to RADIUS SBC).
■ For VSA's (i.e., 'RADIUS Attribute Type' parameter configured to Vendor Specific), the parameter must be configured to any value other than 0.
■ For standard RADIUS Attributes (i.e., 'RADIUS Attribute Type' parameter configured to Standard), the value must be a "known" RADIUS ID (per RFC for RADIUS). However, if you configure the ID to 0 (default) for any of the RADIUS Attributes (configured in the 'Column Type' parameter) listed below and then apply your rule (Click Apply), the device automatically replaces the value with the RADIUS Attribute's ID according to the RFC:
✔ Destination Username: 30
✔ Source Username: 31
✔ Accounting Status Type: 40
✔ Local Input Octets: 42
✔ Local Output Octets: 43
✔ Call Duration: 46
✔ Local Input Packets: 47
✔ Local Output Packets: 48

If you configure the value to 0 and the RADIUS Attribute is not any of the ones listed above, the configuration is invalid.
