Understanding Voice Over IP Technology provides students with the in-depth knowledge of Voice over IP and the TCP/IP protocol that it is based on. Voice over IP technology, or making telephone calls over data networks such as the Internet, has now reached the tipping point, and is expected to eventually become the standard telephone technology. Understanding Voice Over IP Technology provides the integral information needed by Information Technology personnel, as well as management to do their job effectively or plan for future implementations of Voice over IP. For ease of reading, the text is divided into three sections; Voice over IP Overview, TCP/IP the Platform for VOIP, and Voice over IP Technical Details. The sections cover the basics and technical elements necessary, as well as provide review resources for students. To reinforce learning, Understanding Voice Over IP Technology also provides hands-on labs that have been designed to accommodate both classroom and at home self-study. The software used in the labs is freely available for downloading from the Internet.
