Course Description

VoIP network analysis is a specialized subset of traditional network analysis and encompasses not only the skill of capturing data, but also the ability to discern unusual patterns hidden within seemingly normal network traffic. Through real-world examples and hands-on exercises, you will gain a set of analysis techniques focusing on the use of vendor-neutral, open source tools to provide insight into:

VoIP network analysis fundamentals
Data recorder technology and data mining
VoIP-focused network security principles, including encryption technologies and defensive configurations of network infrastructure devices
Recognition of a variety of factors that affect VoIP-based networks and the quality of the voice data
Key VoIP-related protocols
Open source VoIP network analysis tools
Specialized VoIP network analysis, including audio data traffic reconstruction and viewing techniques
You will receive:

Training binder with numerous baseline trace files
DVD with VoIP and networking tools
Library of VoIP network analysis reference documents
You are required to bring your own laptop.
