Goals, Scope and Method
Goals of the Course
•To understand what Voice over IP (VoIP) systems are, their basic architectures, and the underlying protocols
•To be able to read and understand the literature.
•To provide a basis for your own research and development in this area.
Scope and Method
•You are encouraged to examine: SIP Router Project†, Minisip‡, Open SIPServer (OpenSIPS)§, …*
•to understand both the details of the system(s) and
•to abstract from these details some architectural features and examine some places where it can be extended (thususing it as a platform on which you can explore).
