To amplify slightly on Sean's point, Pacific Bell, for a while, only advertised a 800 number, for customer support, that was ONLY dialable from California. I couldn't dial into it from my Colorado offices and there was no general number. Out of state dial-in's were blocked. I had to call-forward through my California PBX to get to PacBell.

I know I've mentioned this before, but dialing US 1-800 numbers (or even 01-800 numbers) is somewhat difficult from a lot of countries. Yes, there are a tricks. But don't assume someone in Korea can easily call a toll-free number. Please always provide an international direct dial number for your NOC.
