Hi, I currently have a hardware PBX with its own custom phones, which I'm using pretty much as an in-house intercom system. At some point in the future I might want to convert to Asterisk. My setup is two analog POTS lines from my local phone company and currently nine stations or extensions, each of which contains the custom phone my current PBX uses. What hardware would I need for this setup, what types of Digium cards? All the different types of cards are a bit confusing to me as I've never done anything like this before. How are the cards priced? Currently I have no interest in ISDN or other digital protocols. I do have Packet8 service, but if I wanted to hook that up to Asterisk I'd probably just use a third POTS channel and hook up the convertor box. I have more questions about software implementation but I'll save those for later. Jayson.
