I get these calls on my cell phone approximately once every day, the number seems to always be different, same call though. Usually they say nothing, I actually want them to say something so I can mess with them. They have called my work number in the past also.
I searched the number on phonenumber.com and it came back as Griffin, K 44 Evergreen Dr. New Britain, PA 18901; a land line with Verizon service, age 37.
This is the now ubiquitous "This is the 2nd warning that the warranty on your vehicle is about to expire" robocall. I believe they are able to spoof the phone number that they are calling from.
