Yep, you'll find that RBC *is* blocking calls from those areas if changing
the ANI to a US number fixes it.  So this isn't an issue of where you send
the call physically, it's an issue of Area of Service blocking for that TFN.
So if you get a US-based ANI to use in cases like these, just stuff that if
a normal toll-free calls fails and try it again.

A specific example I have is calling the Royal Bank of Canada works from a
US Number on our US based providers however sending a Canadian Caller ID
makes the call fail.

1-800-769-2511 is the number.

RBC is not blocking Toronto or Vancouver based telephone numbers from
calling them but when I set the Caller ID to be from those areas, it fails.

find out to where the call should be sent (which IXC - long distance
