“Don’t return that middle-of-the-night phone call if your cell phone only rang once,” warns the New York Daily News:

The Federal Communications Commission on Friday alerted consumers about a wave of “One Ring” robocalls after detecting “widespread overnight calling” in both New York and Arizona. The scam calls, also known as “Wangiri” — which is Japanese for “one ring and drop” — are an attempt to trick customers into phoning the number back. If you do, it can result in getting billed toll charges as though you called a 900 number… “They may call repeatedly, hoping the consumer calls back and runs up a toll that is largely paid to the scammer,” the FCC said in a press release.
