The FCC issued the following consumer alert on March 27, 2017:
The Federal Communications Commission is alerting consumers to be on the lookout for scam callers seeking to get victims to say the word “yes” during a call and later use a recording of the response to authorize unwanted charges on the victim's utility or credit card account. According to complaints the FCC has received and public news reports, the fraudulent callers impersonate representatives from organizations that provide a service and may be familiar to the person receiving the call, such as a mortgage lender or utility, to establish a legitimate reason for trying to reach the consumer.
The scam begins when a consumer answers a call and the person at the end of the line asks, “Can you hear me?” The caller then records the consumer's "Yes" response and thus obtains a voice signature. This signature can later be used by the scammers to pretend to be the consumer and authorize fraudulent charges via telephone.
If you receive this type of call, immediately hang up. If you have already responded to this type of call, review all of your statements such as those from your bank, credit card lender, or telephone company for unauthorized charges. If you notice unauthorized charges on these and other types of statements, you have likely been a victim of “cramming”.

As the Agency that implements and enforces the Telephone Consumer Protection Act, the FCC reviews all consumer complaints. The Agency will continue, when appropriate, to issue consumer alerts based on those complaints and other public information related to possible scams and frauds in hopes of informing and empowering consumers..
