Nevin,

Let's get rid of the nonsense.

Here is a real life NZ number:

Micrisoft New Zealand

09-362 5800

To call it from abroad you need to dial

{you country international access code} 64 9 362 5800

To call it from Auckland, NZ you need to dial 362 5800

Now, which string in saved in an Android phones of MS employees which allows them to call this number from different countries?
