A2Billing has been a very successful open source billing product for many years, however, we feel that it is time to provide a commercial framework in which A2Billing can be marketed and sold to telecoms companies worldwide, while providing a network of support, maintenance and technical consultancy. A2Billing is an open source application, and can be downloaded free of charge, however detailed knowledge of Asterisk and Linux is required in order to build a robust telecom server that can be exposed to the Internet, with the right combination of hardware, operating system and and other dependencies. Star2Billing provides the framework providing the commercial requirements for a telecom company, such as support, maintenance and consultancy.
