GnuGk Sample Billing Platform
======================

This is a system that can be used to provide AAA 
(Authentication, Authorization and Accounting) services 
to Voice over IP networks managed by the GNU Gatekeeper.

It consists of three major components:
	GnuGk (2.0 or 2.2) H.323 gatekeeper (http://www.gnugk.org)
	FreeRADIUS RADIUS server (http://www.freeradius.org) (optional)
	PostgreSQL database server (http://www.postgresql.org)
	
All these application are open source and have been proven
to be stable, mature products.

What you may expect from this system:
1. Endpoint authentication based on a h323id/password pair.
2. Automatic assignment of specified E.164/H.323 ID to endpoints.
4. Restricting aliases an endpoint is allowed to register with.
5. Restricting IP address an endpoint can register/call from.
6. Call authorization:
   - call duration limit based on available account balance
   - allow only fixed set of destination numbers (tariff table)
   - flat tariffs
7. Call accounting:
   - storing call info to the SQL database when the call is started,
     disconnected and in progress (incremental accounting updates)
   - automatic account balance update after call state is updated
     or the call is disconnected
   - support for both originating and terminating account
	 
What you will not find here:
1. User interface (this package contains only SQL schema and configuration
   files for FreeRADIUS and GnuGk).
2. A detailed manual.

Quick Overview

To make everything working you need to:
1. Install PostgreSQL and create a billing database schema.
2. Fill the database with some data.
Either:
  3. Install FreeRADIUS server and configure it properly.
  4. Install GnuGk and enable RadAuth and RadAcct modules.
Or:
  3. Install GnuGk (2.2 preferably) and enable SQLPasswordAuth, SQLAliasAuth
     and SQLAcct modules.
