I actually didn't fully read everyone's comments I suppose some how you guys wanna learn more about asterisk here is the online pdf files that i have from about 2 years ago when i was trying to work on other solutions and stuff in asterisk and never gotten around to fully research and develop changes that i wanted to incorporate into allstarlink.. Of course I am not  a pro programmer like everyone else but had the desire back then to really want to make this program stand out to the ham community and the hobbiest.. I have lost this vision and personally just do enough to get by with my systems.. Its amazing how a medical situation can change your mind on the hobby oh well here it goes the list i have for asterisk education..
