But usually, I will allow my electronic butler to screen my calls when I don't recognize the phone number. (and I also have a nifty feature called "Call Intercept" which has an automated gatekeeper for incoming calls from call centers - so I don't get any salesmen calling during dinner any more - I also have 4 answering options: I can answer the phone, send the caller to voice mail, respond with a polite "I don't want to talk to you" response, or the less polite "We don't take phone solicitations; never call again" response.)
