I don't do alot but it's fun to play with. The only reason I don't do a lot is because I can't have a setup here where I reside, for financial and living reasons. I see your location is in Wisconsin, but we have a VoIP group in Southern Calif. I visit irvineunderground meets on occasion, but I'm mainly interested in their robot and voip groups.

I could hook people up with better links if anyone expresses interest in doing VoIP with asterisk, or just setting up asterisk boxes.
