Just got a call 2 minutes ago from this number. Pressed ignore and sent to voice mail. Got part of a voice mail, the ending said something about adding a warranty and 'press 1 for a live person'.
Just got a call on my cell phone, but did not answer either.
The reasearch shows it to be
Number (301) 223-0068
Exchange 223 appears to be located in Williamsport, MD. (Washington County, Zipcode 21795)
I am glad I did not answer.
