Session Initiation Protocol

SIP training course provides an overview of SIP, its components, and how it works. Also outlines proxy servers, media gateways, encoders/decoders and session authenticators.

We’ll begin the course with overview of SIP protocol and its operation, Then we’ll move on to details on SIP Entities, SIP Messages, SIP Parameters, SIP Signalling, Call Flows, SIP Security and SIP products and trends.

On completion of this course, you will understand the basics of VoIP and SIP. Explore where, why and how SIP is used. You will be able to read SIP messages and troubleshoot call issues.You will get a clear picture of SIP architecture and its components. Understand the difference between SIP and H.323.
