Publisher's Synopsis
According to IDC, the VoIP market is projected to grow at 50% per annum on a conservative basis for the next five years. By 2005 over 20% of all calls will occur over the Internet or corporate intranets. Gateways that can transmit voices over a company's otherwise data-only IP networks are expected to serve as precursors for translation software that will send voice, fax, and video over the Internet.;Networking expert Gil Held shows network managers techniques that can be used to transport real-time voice conversations over networks designed for data transmission. Features of the book include: applications notes in each chapter showing how to implement the technology, such as how to route call centre calls over an IP gateway; cutting edge material on voice over IP gateways and QoS (quality of service), including why it's needed, and how it can be obtained; and in-depth explanation of how to transmit voice over private IP networks, the Internet and intranets.
