Nitin Sagar, CCIE #37525


The Advances Technologies Videos that Mark Snow has put together for CCIE Voice is amazing. I specifically want to mention the Gatekeeper and CUBE topics that can be a little daunting to understand initially. However Mark being a seasoned trainer, has lectured on those topics so well that the concepts will remain me for a long time. Mark, I want to thank you for the splendid videos.
