Course/Exam Encapsulation

The VoIP Illustrated course is encapsulated within the SIP/VoIP Illustrated hybrid/master course. Questions for the VoIP expert exam are taken only from Modules tagged as ‘VoIP Illustrated’ or ‘SIP/VoIP Illustrated’. The key VoIP items are highlighted (yellow color) below.

Contents and methodology    

VoIP concepts, architecture, call flow examples, hands-on eLAB and 50 puzzle pieces, which together make up the big VoIP puzzle.

Contents and methodology    

16 hours on the basics of SIP/VoIP plus advanced topics. Utilizes the TDvL (Top Down via Links) and LBE (Learn By Example)    methodologies. The Top level (156 pages) provide 3 first hours of SIP and IP Telephony overview. Next layer (550 pages) provides additional 5 hours of deeper dive into the details of the protocol plus coverage of advanced topics such as Security and Instant Messaging and Presence. The bottom two layers (812 pages) cover all the Nitty-Gritty details and nuances of the protocol (in 8 hours) - mostly via detailed examples.

Intended audience

SIP/VoIP Marketing and Technical people as well as Developers who need to dive into the details.
