The SBC Edge Portfolio supports the logging of accounting and call metrics related data on RADIUS based accounting servers, functioning as a RADIUS client sending Call Detail Records (CDR) to RADIUS accounting servers.
The CDR feature of the SBC Edge Portfolio enables administrators and users to gather a wealth of information specific to calls placed and/or received through the SBC Edge Portfolio. Call Detail Records are stored on a RADIUS server using both a standard Radius Dictionary and a Ribbonspecific RADIUS Dictionary that can be retrieved from the server at anytime. Depending on your RADIUS server configuration, records can be stored either in plain text format in date coded log files, or directly in a relational database.
The CDR feature provides information on incoming and outgoing calls for accounting and administration purposes. The SBC Edge Portfolio collects data for every call and reports it to a third-party RADIUS-based accounting server in the form of Call Detail Records which consist of attribute/value pairs. This data includes, but is not limited to attributes such as:
- Date, time and call duration for all calls
- Dialed number and calling number for all calls
- Codec negotiated for all calls
- Call Quality metrics, values from RTCP-XR
For backwards compatibility, the vendor ID in the CDR record remains unchanged.
A typical CDR contains entries similar to those shown below:
