Description

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!
