Answering Machine

[dual]

I wonder whether there is an Answering Machine which has the ability to set different greetings for contacts.

Thanks for your help.

The answering machine is in the network, not the phone. So while it would be technically possible, there's no app or hack on the phone that can give you that.

You can do it by using Google Voice.
