VoIP: An In-Depth Analysis

Chapter Description

This chapter explains many of the issues facing Voice over IP (VoIP) and ways in which Cisco addresses these issues.

Summary

This chapter brought up many of the issues surrounding 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 these effects on VoIP networks.

With careful planning and solid network design, however, you can control and possibly avoid many problematic issues. Some of these issues are jitter, overall latency, handling delay, sampling rates, tandem encodings, and dial-plan design.
