I received a call on 10/16/09 at 8:21 pm. We have caller ID, but it said "out of area" so my son answered the phone thinking it was someone we knew. The guy on the other end had a heavy accent, I didn't hear what company he was calling from, but he said he was not selling anything, only doing a 30 second air quality survey. He asked me some air quality questions, then got to personal questions like whether my husband and I work full time, what is my first name so he can validate the call, etc. I told him that he called me so he should know my name already. I was uncomfortable so I hung up. Then I redialed the number and an automatic voicemail came on to say that "the person you are calling has do not disturbed activated and is not accepting calls at this time, good bye."
