trying to play my ps3 online but it says it cant find a connection (i do have it plugged in rite and installed and everything) and i need to adjust the WLAN security settings

I'm getting a Cisco 1701 which I know supports VOIP and considering a 2621XM to learn. I know both can do PBX (am I right?). I'd like to use a VOIP phone (or two) and use a land line. Also, I plan to set up a point to point connection to peer wanting to do similar. If I wanted to set up voice over land line what do I need to do, and cheaper method is best. I've heard of DID and FXS. DID is more expensive, the cards I've found. What interface cards would I need to accomplish inbound and outbound calling for as cheap (within a 100 range) as possible but functional.

Also, say I didn't use a land line though defeat a big purpose, can I still set up two Cisco IP phones linked? Do I need Call Manager Express, is there a cheaper solution like computer based software?

I'm confused on logistics and how I could go about this. If anyone could provide info, it would be great!

What is the best way to trouble shoot this problem? I have a Windows XP client. The Cisco ATA is set to allow everything out bound and I've ever tried setting up an access rule to allow anything two/from this machine. Is there some way to make windows log what's wrong? The Error is the other end is not answering. I've tried this same laptop offsite and it's able to connect fine.

The link to the cisco site seems to be if you wanted to auth to another ASA device. i'm basicly just trying to pass through from a win XP box to a Win2k3 server out on the internet. Interestingly enough, I have no other kinds of VPN issues.

Cisco's website lists a range of transmit power between -3 and -9.5 dbm. That's quite a range, and it makes me think there's a way to adjust it because it seems doubtful they'd manufacture the thing to such a loose tolerance. But every time I've used a GBIC, you just plug them in and go, there's no configuring specific to the GBIC. What's the deal?
