I got a call today also from this number. I am on the do not call list too. I answered the phone but said nothing, neither did the other end of the line. They hung up then got back on the line but they did not get a dial tone because I didn't hang up. They did this two more times then my service disconnected the call.
File a complaint with the FTC and then call them back and let them know. A Florida company was fined $7.5 Mil for calling people on the Do Not Call Registry.
This call was made from this number twice. When I tried to return the call, they would not pick up. I am on a do not call list and how they got my cell phone number I will never know. I would like to file a complaint against this company and the people behind these calls.
