Same as others have reported --- 1-2 rings and a hang-up.
Call it back --- long time to connect, 3 rings, and silence
What is the purpose of this stuff?
Report to the DoNotCall web site anyway even though it seems nothing is being done. Better yet, complain to FTC & FCC - online forms available. Most likely a scammer & they will continue to call using other spoofed numbers. They are trying to get you to call the number back - here is one reason among many: http://www.consumer.ftc.gov/blog/one-ring-cel ... ing-your-wallet
