Asterisk Part 3 - Using Extensions with Asterisk

In the third video of this 10 part series on Asterisk, I explain how to use "extensions" in Asterisk. We configure extensions to allow users to place and receive VOIP calls. Due to Youtube's small video size, some of command line stuff is hard to see. You can view a 640X480 video on my website: www.HotButteredIT.com. They are currently free, but I'll have to keep an eye out on the bandwidth usage. Enjoy!
