I'm new to VOIP and not sure if anyone could help me in this group. I have a small home office but I'm thinking about adding on and opening up a small computer shop. I was wondering if anyone knew of a quick and cheap way so set-up just a lan voip system. This way I could contact any employee from in the building. I bought a Linksys PAP2 adapter thinking I could use it but, it only works with vonage which I heard bad things about. Anyway I could use that to hook-up my own system ?
