Who called from 5712141504

Got many calls from this number and none of them left a message. Of Course my number is on the DO NOT CALL list.

Multiple calls - up to 10 per night from this phone number.
Who is this????

Called me 9 times so far today, almost every half-hour!  Nobody on the phone when I pick up.  So annoying!!

I got 8 calls from this number today I answered it some guy said 2 things and it was a man with a very deep voice. I got the call back and it was an opinion poll.

Hi, I've been receiving multiple calls a day from this number. It disconnected immediately after I answered on the 4-5 times I have tried answering it. I have learned that it is possible for other countries to buy US lines to make calls from. Also learned from a dr. friend that sometimes it's a way to find out what time of day the family is home so that telemarketers or politicians can know when to call back and get an answer. This happened a few months ago with another telephone number and eventually if you just keep ignoring the calls, they will stop.
