The wiki is growing. I add something, someone else corrects it, I add stuff again, someone else add more. Finally, we have a very helpful and informative document.

On this wiki, you\’ll find much documentation for the Asterisk Open Source PBX. In addition to that, many VOIP terms explained and pointers to other sites on the net, both VOIP vendors, Open Source Projects and information sites.
Go there, now!
