Overview

Understanding Voice Over IP Technology provides students with the in-depth knowledge of 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. The text is flexible enough to be used in the classroom, at home, and in the workplace.

  • The selection of course material, its presentation and pacing as well as its technical depth, has evolved through many classes and multiple revisions.
  • The course is easy to teach for instructors who are technically competent in TCP/IP and take the time to study the Voice over IP material.
  • This is particularly important for any training facility that does not have a VoIP specialist available.
  • The classroom is easy to set up because it uses standard Windows machines. The equipment for labs is modest because only a soundcard and headset (microphone/speakers) is are required. In addition, only software that is free to download from the Internet is used for labs.
  • The design of the course is flexible. The book is divided into sections. A section can be skipped if it doesn’t fall within the scope of the course or if the students have already met the prerequisites.
  • It can be used for instructor led classes, on-line courses or self-study. It will also be a valuable reference guide after the course is over.
  • The accompanying CD-ROM includes the slide show for the course and the software used in the hands-on labs.
