Course Overview

In this seminar you will learn the advantages of the Session Initiation Protocol. You will learn How IP telephony is utilized SIP based networks; review the typology, architecture, protocols, and special applications. We will further discuss the SIP based telephony markets, various products, infrastructure and services. During the seminar we shall have practical sessions of analyzing SIP and SDP Captures.
