Hey there! 

Welcome to this Introduction to SIP Course! I'm Chris Morin, and I'd like to welcome you to this wild world of SIP!

Working in Telecom, I've noticed that telecom has begun to take over all departments of IT. More frequently there is no longer a separate "Telecom" team because Telecom Touches Everything now

This course is designed to enhance your skill-set by bringing you up to speed on how SIP works in today's modern telephony infrastructure.

Are you a Server Administrator? Congratulations, modern phone systems now run on top of your servers.

Are you a Network Administrator? Congratulations, modern phone systems now communicate on top of everything else in your environment!

Are you a Telecom Engineer? Congratulations, modern phone systems are moving away from being separate "boxes" of technology. We've now got to get along with the neighbors!

Are you an IT Manager? Congratulations, you've identified a trend that the industry is going through - a migration to SIP! For better or for worse you ask? You'll see!

No matter where you come from in the IT world, I can guarantee that SIP is going to touch you in some way, shape, or form in the future. I designed this course to enhance your ability to work with the SIP protocol in your work environment, troubleshoot effectively, and make competent infrastructure decisions surrounding Telecom.

This course covers the foundations of SIP, and should provide you with a working knowledge of the protocol that can be applied in every day work life.

What are you waiting for? If you don't understand SIP sooner rather than later, you're sure to be blindsided by it. Let's be proactive, and learn the basics of SIP!

This training was created for the IT staff of mobile/telecom providers, ITSPs (Internet Telephony Service Providers), Consultants, Call Centers or any other company using IP telephony.  The performance of these professionals is essential to reduce the churn and the stress of the operation. SIP troubleshooting is a key skill in these scenarios. 

It is a result of years in the frontlines of the tech support of a softs-switch developer, troubleshooting hundreds of deployments.

I have prepared two FREE gifts for this training. The first is a Virtual Machine in open virtualization format with a SIP server running as a Proxy, B2BUA and Redirect.  The second is a list of SIP responses with comments on how to troubleshoot the most common SIP error messages. I sincerely hope you enjoy this training.

There are 5 practical labs to do with your VM and softphones in this training.

SIP is  the standard in Voice Over IP communications.  Large telecom carriers are switching away from their legacy platforms into highly scalable next generation SIP networks. Even cellular phones are migrating to Voice Over LTE, which also relies on the SIP protocol.

By taking this course you will learn the fundamentals of the SIP protocol.  Knowledge of SIP has enabled me to land secure positions with world wide telecommunication companies. Are you ready for the same opportunities? 

In this course you will learn: 

  • What is SIP and the RFCs that it is defined in. 

  • The different types of SIP clients and servers

  • The structure of SIP messages

  • Overview of SIP response codes
