Called home. Said they were with Braun Research. Indicated that I was on the national do not call list and if their number appears I would report them. Their response was "have fun with that".
this number called twice within a few hours. the phone rang 3 or 4 times, then they hung up and left no message. looks like it is a number from miami and their service provider is bell south: http://anireport.com/lookup/3056491355/
