I started supporting call centers 14 years ago and at the time I had no experience with phone systems. Eventually I learned them inside out and started using Asterisk and Linux to reduce costs. I discovered how versatile and robust Asterisk was so I expanded by client base to sell business phone systems.
After 14 years I have turned to focus my efforts on training how to build and sell phone systems. My instruction is very actionable, I want students to take the knowledge they gain and start using it to make money or do what they choose to do with it. You will find my teaching style is well liked by my students and they are always looking for new and exciting courses from me. Just take a look at some of the reviews I have received below.

"Interested in providing VOIP services? Take this course, Even if you plan to use FreePBX or another GUI interface for your VOIP service, learning Asterisk and Linux will give you a better understanding of what's going on under the hood of your PBX.
