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 :)
