eLAB Encapsulation

Two stand alone eLABs (SIP and VoIP (RTP/RTCP/DNS)) are encapsulated within a hybrid/master eLAB module. This module is encapsulated within the SIP/VoIP Illustrated hybrid/master course. One end to end SIP/VoIP Call scenario exercise is used to generate the call logs for both eLABs.

Contents and methodology    

90 pages module with interactive LAB exercises and solutions (based on X-Lite soft phone) accompanied by two Ethereal ( aka Wireshark) capture files with live SIP registration & SIP call setup scenarios and RTP/RTCP traffic.

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 the student learns how to work with it.
