I work at a public library reference desk and we get calls like this frequently. It was a recording about refinancing my mortgage from an unknown company. It stated I could press 1 for all the details or press 2 to remove the phone number from the calling list. I pressed 2 but I have no idea if that is effective. I considered pressing 1 for the details and then wasting the person's time when they answered but hey I'm at work and that's not what the phone here is for.
Also received a call from this number identified as DC SUBURB, VA .
I called it back thinking it was a customer, but an automated service picked up and recalled my number then requested that I push 1 if this was my number. Obviously an advertisement.
