You are confusing number portability and call forwarding
I am not confusing anything. Nobody said anything about number portability in the above quote.

But in fact with local number portability, you cannot rely on the county code to tell you where to route a telephone call anymore. Which is many calls result in a data dip to provide you the routing information from a central repository.
OK?
Just pointing out that some assumptions about how voice call works is not true. Nor would it be smart to send traffic to another part of the world unnecessarily. Local calls stay local even when roaming. Please remember that signaling and voice is separate in the telco world which is why it compares poorly with IP. Except for the LISP protocol which does something similar.
