Sthokie: Thanks for posting the link for noblecom.com
After looking at the prepaid Global Call card from noblecom.com, it really looks like the best bet for international to US calls. On the downside, the cards are one time use prepaid only .. no recharging, so you have to plan ahead .. they are good for a year from first use.
The per-minute rates are really cheap and there are no surcharges, and it's the AT&T network. It doesn't say on the web site if there are countrywide toll-free access numbers or not. Does anybody know if they use the AT&T countrywide toll free numbers for calls originating overseas?
They don't have a phone number posted.
They don't appear to have any country-country access for non-US calls. but I only tried one or two combinations.

P.S.: I found a number I had written down for TTI National customer service in case anybody wants it: 800 893 5094. This is a number that they actually answer as "TTI National".
