Length: 2 days

Overview

Description: This course will provide a working understanding of SIP (Session Initiation Protocol).  SIP is a signaling protocol used for controlling multi-media sessions.  It provides a way to establish voice, video and advanced messaging between devices.  Today it is finding new uses in telephony applications, conferencing and instant messaging.  The focus of this course will be how SIP is used to setup and release calls in a packet network including calls that originate and / or complete in the Public Switched Telephone Network (PSTN). The student will have a practical understanding of the messaging and the protocol structure, and analysis of the protocol for various services is provided.
