RADIUS
Remote Authentication Dial In User Service, more popularly known as RADIUS, is used by telecom service providers for the purpose of authenticating, authorizing, and accounting for the use of services by subscribers. A RADIUS server is an application server that provides this functionality. It can take as input as well as output Call detail record (CDR) data.

TelcoBridges and RADIUS
Starting with release v2.3 of Toolpack, explicit support for the accounting function of RADIUS is now offered. Previously, Toolpack stored Call detail record (CDR) data in a local database. Starting with Toolpack v2.3, CDR data is stored on a dedicated, external server running an implementation of the RADIUS standard. Configuration of the location of the RADIUS server is performed through the Toolpack web portal. For this initial release, Toolpack only supports the Accounting functionality of RADIUS; it does not support the Authorization or Authentication options. That type of functionality can be performed outside of RADIUS using Toolpack.
Starting with release v2.6 of Toolpack, multiple RADIUS servers can now be configured for backup purposes.
Prerequisites
In order to enable RADIUS functionality in Toolpack, you must have a RADIUS server already up and running. It is highly recommended that the RADIUS server software being running on a separate machine from the one running the Toolpack software. Before configuring Toolpack, you will need the IP address of the RADIUS server(s). You will need to specify a ‘secret key’ which will authenticate the Toolpack server so that it can send CDR data to the RADIUS server and the RADIUS server will accept it.
Configuration
Assuming that you have already set up and configured a RADIUS server, you also need to configure Toolpack.
