Really rare to find such a clear explanation about a semi-obscure subject like this, saved me at least half if not a whole hour of trying to figure this out by myself

No stupid jokes, no mumbling, no unnecessary explanation... I had no idea what SIP was until I watch this. This was a great tut sir, seriously thank you!

I wish more tutorials were like this. No time wasting, but still friendly and highly informative. But best of all, the video did not start with : "Hey! What's up guys!".

Explicit explanation with appropriate examples and reflections, awesome!

[anuragrauniyar]

simply amazing! The creativity to explain the basics is just incredible!

Can you continue tutoring for network security concepts? I'd probably learn more from your videos than from paying for college.

Wow! This video should be a template for anyone who wants to do YouTube tutorials. The last video I saw was some dude fumbling over a whiteboard for 10 minutes, and I was none the wiser at the end of it.
