I received the same call from Kenneth  Burruss on 9/1/12. Sounded like he had an Indian accent. He started by telling me it wasn't a sales call. He asked me if we had a fire alarm, if we checked it semi-annually and if we  had fire extinguishers. He then asked if I owned the home and for my name. When I wouldn't give him any information on my name...he started to talk faster and push. I hung up. He immediately kept calling back (caller id showed 5 or 6 times without letting it go into vm). I finally picked up and told him that I did not wasn't interested in talking further, that I did not want any more calls and that I was going to call the police if he called again. He then said he was 'going to kill me'. Incredulously, I asked he to repeat what he just said and he repeated it in a very controlled way. I let the local police know.  They called the number and got someone who said that their number was being used to make calls and that the calls might be coming in from outside of the US and they were looking into it.. That is as much as I know.
