Usage Example: Prepaid Calling

Using only OpenSource components, one can build a prepaid-calling system.


The GNU Gatekeeper would handle

  • call authorization and accounting
  • enforcing limit on call duration
  • easy integration with Radius and existing billing systems

Example Configuration

The GnuGk distribution contains an extensive example. See the contrib/sqlbill/ directory.
