What it is

As part of our CBT training (eLearning) we provide you a hands-on (virtual) LAB experience.

In more detail

Our combined SIP Illustrated and VoIP Illustrated eLearning course incorporates a 90 pages SIP/VoIP eLAB module. This module provides you a step-by-step virtual tour of a live call. It enables you to play with the call and analyze it (both SIP/RTP) by using the Ethereal (aka Wireshark) call trace analyzer.

Intended audience

SIP/VoIP developers

Prerequisites

No prior knowledge is assumed 

Outline

90 pages of two stand alone labs (SIP, VoIP) with exercises and analysis. SIP/SDP/RTP/RTCP/DNS are analyzed in depth. Day to day issues such as NAT traversal and early media are carefully examined. All RTP/RTCP fields are explained and cross referenced with each other. Topics such as packetization interval, port assignment, the use of RTCP for unicast sessions are covered in depth and are learned by example. As a by-product the Ethereal (Wireshark) analyzer tool is introduced, and you learn how to work with it.
