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

A CLEC which received a call to a TFN does SS7/TCAP request to its TF lookup provider in order to find out to where the call should be sent (which IXC - long distance carrier) to. If no carrier for originating area of service returned - then a type of message preconfigured on TFN's record must be played back to a caller.
