* A telephony tutorial for network managers
* Comparative assessments of voice over frame relay, ATM, and the Internet
* Overviews of all the enabling technologies involved
* In-depth coverage of voice characteristics, compression standards, and QoS
* An extensive case study illustrating the pros and cons of voice over data
* Guidelines to help you decide when ( or whether) to invest in voice over data technology, and how to choose the best type for your organization
