Phone systems, service, data networks, and the Internet are critical pieces of any companys communications. And most IT professionals dont understand the effects of deregulation and parallel technologies on the bottom line. Telecommunications companies have more than a 30% error rate on their billing each month. There are only about 4,000 telecom consultants in the country who do nothing but find errors on bills. The economy seems to be crying out for just this type of study. This work explores the various technologies in terms of cost and ROI, sets up some case studies to solve real communications issues, offers cheap ways to meet bandwidth requirements, looks at the players in the marketplace in terms of technology as well as cost, explains what a tariff is and how it can be made to work for you, gives a better understanding of telecom taxes, which ones are required and to what degree, and provides international strategies to manage costs of a national and global network. Reading this book will be like hiring that telecom consultant.
