So how do you know when you're really getting a call from Egypt?
In this case, he's lucky, because Egypt has minimum 2 digits area code + minimum 8 digits subscriber number. E.g. +20-12-12345678 (at least 12 digits total) vs. a call from Idaho would be fixed length +208-123-4567 (10 digits). So he could run his pre-processing only on numbers that are longer than 10 digits :)
