[Asterisk-Users] How to get started, what do I need?

[Jayson Smith]

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.
