Greetings all,

I have a Vonage line servicing my home. With it most of my international calls are free. There are some other countries that I can't call with Vonage. Plus, I'm interested in some other features that I can't get with this service.

I'm very interested in free/cheap VOIP solutions that would help me achieve my targets.

That being said. Is Asterisk the best way to go?

What are my hardware requirements besides a decent linux grade server?

Do I need a Digium card that I keep reading about?

How does it integrate with my setup? I have my ISP provide me internet and cable. There's a Vonage box that plugs itself into the ISP's modem/router. My phones connect to that ATA box.
If it turns out to be cheaper, I can just ditch Vonage and go VOIP via Asterisk completely.

How do I, by using a dialplan, call this VOIP box from my cellphone and get routed to a preset international call? eg. I would like a preset number to be dialed from my home line, where this VOIP solution resides, when my cell phone calls it or dials an access code or something. Please let me know when my scifi goes beyond today's tech.
 
Anything else I need to be aware of?

Any current guides or how-tos with pictures will help, but I need advice.

Thanks for looking. I can branch off with more points later. I know I've asked a lot.
