Got the call on my mobile. Heard some DTMF tones, then it hung up. Calling the number back, I got a recording about a "US Prescription Card" which prompted me to leave a message with name and address. No thanks.
The phone number is apparently registered to Verizon wireless. I tried calling them to report abuse, but they wouldn't take a report because I'm not a verizon customer. They suggested I call the police.
I'm reporting it to the FCC. I suggest everyone does the same. Google "FCC complaint"
Received a call on a mobile number. Answered and the call disconnected after I said hello.
Unknown purpose, but thanks to this wonderful site, I know to add it to the list of numbers not to answer as it is likely a scam.
