Call anywhere on your cell phone for $5 with Asterisk
I was searching for some PHP info when I came across this cool article. It describes how one could use asterisk@home with your cell phone and call anywhere in US for $5 a month. If you shudder when you have to pay your long distance cell phone bills, and if you have some ingenuity, you could save a bundle.
Article is very informative and is rather long. But it certainly is interesting read if you are interested in VOIP- IP telephony.
Have a good read at Nerd Vittles.....
