I have a good friend who works for Verizon and they along with police are warning about a new phone scam aimed at getting people who answer the call to say the word "yes." ... Once they have a recording on file of your voice saying "yes," scammers can then use it to authorize unwanted charges on bills, credit cards and more! I've gotten a few calls from numbers I don't recognize just this week. My advice is not to pick up and if it's important enough, they will leave a message.
