Engin allows any broadband user to make and receive calls over the internet whilst using their existing telephone or an Engin Internet phone. The easy to use service drastically reduces customers phone bills, whilst offering a range of free included features enabling users to actively control their own calls. Engin was the first broadband phone service to be broadly available to Australian consumers and businesses, and the first on the shelves of major retailers. Today they provide services to almost half of the broadband phone market.
