Page History

The Call Accounting Manager (CAM) generates Call Detail Records (CDRs)

and supports accounting event logging on the

the ACT logs during call debugging (to get the originating trunk group, calling and called numbers, codec used, etc.).

You

can also view billing records (and other logs)

while in EMA Platform Mode.

Refer to Administration - Accounting and Logs for more information.

Accounting File Version

the SBC Core release V08.01.00 is 93.00.00 (major CAM version is

93, minor CAM version is 0, a special CAM version is 0).

File Header

Every event log file, including accounting logs, contains a file header. This header consists of a 128-character string terminated by a carriage return. Each field in the event log file header is defined in the following table:

File Footer

The one line footer, below, is appended to each log file (including accounting logs) when the file is closed under controlled conditions.

DDMMYYYY HHMMSS: File administratively closed.

Controlled conditions include CLI commands (for example, set oam eventLog typeAdmin acct rolloverAction...) and automatic roll-overs when maximum file size is reached.

When an uncontrolled file closure occurs, such as an

Renaming Open Accounting Files

The SBC includes the ability to rename a currently-open accounting file using a known suffix to make it easily identifiable by external applications. To activate this feature, simply enable the flag “Rename Open Files” using EMA GUI or CLI. 

CLI syntax example:

% set oam eventLog typeAdmin acct renameOpenFiles enable

Once this flag is enabled, on the next accounting file open activity, the suffix .OPEN is appended to the filename using the format <shelf><sequence number>.ACT.OPEN (currently open files are not affected).

For example, as accounting file 1000099 is created with this feature already enabled, the file is named “1000099.ACT.OPEN”.

For configuration details, refer to:

• CLI: Event Log - CLI
• EMA: Event Log - Type Admin

Accounting File Roll-Over

The 

When accounting file names reach the maximum value of 1FFFFFF.ACT, the next file name rolls over to 1000001.ACT. Use the “Rename Open Files” flag to rename the most recent accounting file with the ”ACT.OPEN” extension. This flag is accessible from the EMA at “System Configuration” > “CDR and Servers” tab.

Global Charge Reference

The Global Charge Reference (GCR) feature allows correlation of calls across networks where the calls are originated from and terminated at different third-party devices. The GCR field is populated in the CDRs of the SBC if the GCR is received in a gateway protocol message from a GSX9000.

The GSX9000 receives or generates the GCR parameter through an ISUP parameter. The GCR is used in conjunction with SIP call-id’s to associate calls that interwork between SIP and ISUP protocols across multiple network devices.

CDR Server Remote Port Configuration

The 

Use the following parameters within CDR server configuration to set up remote port and ssh key based authentication:

• cdrPort
• useSshKeyFile 


• generateSshPublicKeys

To generate a new SSH public key, execute the following command:

% request oam accounting cdrServer admin primary generateSshPublicKeys

The generated SSH public key must be installed on CDR server to use ssh key based authentication from SBC. The SSH public key must be copied to the remote CDR server file /home/<user>/.ssh/authorized_keys. If the private key is compromised, the key must be re-

generated. Once the key is re-generated, the CDR server must be updated with the new key.

RADIUS Accounting Support

Remote Authentication Dial In User Service (RADIUS) is a standardized protocol for supporting Authentication, Authorization, and Accounting (AAA) management in a distributed client-server architecture. The 

The following accounting message types are supported by RADIUS protocol:

• Accounting Request
• Accounting Response

The process for sending accounting requests and responses is described below.

• The

  Spacevars
  0 product

   sends an accounting-request with Accounting-Status-Type value "Accounting-on". At a later time, this transaction informs the server about the new accounting client that will send the accounting messages to the NAS/resource usage by user.
• When the

  Spacevars
  0 product

   connects the call, the accounting starts. The accounting-request contains the Accounting-Status-Type with the value "Start". The "Start" records contains the following:
• User identification
• Network address
• Point of attachment
• Unique session identifier
• Next, the

  Spacevars
  0 product

   records the status change by NAS to the RADIUS server for this active session. The accounting-request now contains the Accounting-Status-Type with the value "Interim". The interim record usually conveys the current session duration and information on the current data usage.
• When the user network access is closed, the NAS issues a final Accounting Stop record to the RADIUS server, providing the information on the final usage in the terms of the following:
• Time
• Packets transferred
• Data transferred
• Reason for disconnect
• Other information related to the call

The Accounting-Request contains the Accounting-Status-Type with the value "Stop". The primary purpose of this data is to bill the user. The data is also used for statistical purposes and for general network monitoring.

Generating CDRs in Q-SBC Format

By default, the SBC Core generates CDRs in the standard SBC Core (former Sonus) format. For deployments that require it, users with admin privileges can configure the SBC Core to generate CDRs in the format of the (former GENBAND) Q-series SBCs. Similar to SBC Core CDRs, the Q-SBC format is an ASCII-format text file with multiple records per file. When you enable the Q-SBC format, the SBC Core populates CDR log files according to the mapping shown in the Q-SBC to SBC Core CDR Mapping table. Refer to Generating CDRs in Q-SBC Format for more information.
