ATC Video 28: Why is Seattle to Seattle localized as 10D and not 7D?
In ATC Video 28 "Incoming PSTN Call - Calling Number" - Mark is illustrating the principle of "Localization at Call Egress".
However the Seattle Ph incoming call via PSTN is localized at the destination Seattle IP Phone as 10D, viz., 2065015111.
Why isn't the ANI localized as 7D - 5015111?
Is Seattle a 10D NPA?
