This number called my cell phone as well. The caller id stated the call was coming from Indian Head, MD. No voicemail was left. I called the number back and it stated that all operators were busy and if you wanted to be added to the do not call list to press 1. I pressed 1 and the operator stated that I would be added to the do not call list and then gave a number to call if I wanted to know the name of the business and address of the company that was trying to reach me. I didn't bother to writer the number down because it sounded like a telemarketer.
