What is the best way to set up an "Outbound Route" for all USA, but exclude non-USA (e.g. not Canada, Caribbean, etc.)?
Should I just list out in Outbound-Route's "Dial Pattern" all 325 or so USA area-codes, or will this be too much cpu time (setup for each call)?
(I need to do this because I have a mix of VOIP trunks and FXO to POTS -- the POTS lines are fine for in-USA, but outrageous cost for out of USA.)
There is a similar question here:
but no one really answered that posting.
