Can someone tell me how to dial 800 and 888 numbers in the US from > Toronto?
Basically, if they don't want calls from Canada, you're out of luck.
When you sign up for an 800 number in the US, one of the options is calls from Canada. Some take it, some don't. I turned off Canada calls on my main 800 number because I was getting a lot of expensive wrong numbers due to my number having been handed out to half the insurance agents in Toronto as the claims department of a large insurer.
R's,
