This is the "Rose Law Firm" and they are bill collectors. They usually use an auto-dial computer that routes you to a collector when you answer. If you pick up the call and a voice asks if you want your number removed because you are not the person in question and you offer the correct response they forward you to a collector who refuses to remove you phone number anyway!
They called me regarding a doctors bill from this number. Annoying but they were good to work with. I ended up paying the bill as I was not aware of it previosly.
