Just rec'd. a call from this # so for the heck of it I decided to answer it.  You first get a message that a doctor has recommended you to receive a medical alert system absolutely free and to press a # to speak with someone.  I did and this lady came on and spoke with me.  I told her I would have to know the name of the doctor who recommended me.  She said they didn't give her that info.  Told her I would have to know that to prove this wasn't a scam.  She then told me what my address was; I agreed and told her that was common knowledge and stated again that I wanted the name of the doctor.  She paused and then hung up on me.  Definitely a scam.
