This class' focus is on Asterisk in a SIP network environment. With a combination of theory and practical labs, you will learn how to install, setup and configure Asterisk in a scalable enterprise or service provider network. We will go through various kinds of setups and give you insight in the design of real SIP networks.

 What you will learn in this class:
Asterisk basics - a recap
A quick update on Asterisk on a technical level, the core design, channel architecture, codecs, formats and various modules
SIP - an introduction to the protocol
An introduction to the SIP protocol. Design ideas, basics, methods, transactions and call features. SDP - the Session Initiation Protocol and RTP, the Real Time Protocol is also covered.
