In this download, SearchVoIP.com brings you Chapter 7 of Voice over IP Fundamentals, "VoIP: An In-Depth Analysis," which discusses some of the issues that both developers and users need to consider when working with VoIP. Many of these issues, such as compression/decompression of the speech frame and propagation delay, are inherent to VoIP, and you can't do much to minimize their effects on VoIP networks. This chapter explains how, with careful planning and solid network design, you can control and possibly avoid many problematic issues like jitter, overall latency, handling delay, sampling rates, tandem encodings and dial-plan design.
