This is a real problem at times and I hope someone will actually be able to answer the question. I think it's pretty clear from the posting that SAAdFlyer doesn't mind incurring toll charges, the problem is that the 800# simply doesn't work from his location.
I have had the identical problem while attempting to dial from several countries. As an aside, as indicated by several other posters, the 800 number will work from certain locations. However, I doubt this info is of much use to SAAdFlyer since these locations appear to be far removed from his/her present position.
