[wplug] IP telephony for beginners

[Justin Smith]

The Asterisk book looks like a nice resource, but it assumes that you 
already have a basic understanding of telephony. Besides that, I don't 
like to use vendor-specific materials for general overviews, because, 
well, that's not what they're for. 

If it was up to me, I'd use Asterisk. Unfortunately, my employer decided 
to pass it up in favor of a proprietary phone system, so I need 
something a bit more general.

I ended up finding a /fantastic/ series of classes on YouTube by "Eli the 
Computer Guy." Here's the one for Introduction to Telephone Systems:

Eli explains things exactly the way I do: he goes through things step by 
step, not assuming that you know anything. He drills down each topic a 
couple of times and then comes back to it at the end for a recap. There 
are prerequisite classes listed in the video description as well as cliff 
notes if you want to refer back to the basic concepts.

He has videos for telephony, networking, and more. I strongly advise 
anyone who's interested in studying complicated technical subjects to 
check out Eli's videos.
