203-445-7700 - Looks like a CT number.
I wouldn't be so quick with that conclusion. In telephone parlance, the CT number would be +1 203.445.7700. The +1 being the international code for the US.
+20 is the international code for Egypt. Alexandria has the "area code" of "3".
To dial an international number from your phone, start with "011", then, for these clowns, "20 3 445 7700"
