Maybe there's a difference North-South about privacy.
Here in Italy, as fare as I know, the one who answers at the phone (if it's not a business phone) is not supposed to tell his/her name, on the contrary he/she expects the caller to give his/her name. Meaning, you have called, I'm not going to tell my name, in my home, to someone I don't know: it's up to you, caller, to tell who you are, then I will see.
