[Asterisk-Users] What I need to make this work?

[Bill Flood]

Hello!

I just joined and am looking around for a place to start.  Would this 
Asterisk Developers Kit be a good place to start?

This is what I'd like to do.  I am a wireless ISP.  Several of my customers 
have offices in different communities that I serve.  The local telephone 
company charges  8-10 cents a minute for calls town to town.  Currently I 
use a Cisco ATA 186 to talk to one of my programmers in another town using 
the FWD gateway.  Could I implement the Asterisk software and what 
recommended hardware to connected these users through the Asterisk head end 
to place calls and log their activity for charge back?

I'm considering having up to 12 VOIP users, possibly 2-3 concurrent 
users.  If I load RH 8.0 what's the minimum hardware requirements 
-CPU/RAM?  Any other suggestions/ ideas would be appreciated.

Thanks,
