This number is from the American Lung [***]'n and as a charity, they are exempt from the Do Not Call list. It is probably dialed by a computer and then turned over to someone in a boiler room. If it doesn't get turned over to a worker quickly enough, it will appear there is no one there.
Called two days in a roll. Then reverted to Out Of Area when blocked. The number belongs to the American Lung Assoc. another charitable rip-off. It appear they get number from hospital from families who have member suffering with lung ailments
I kept getting this call also. It is the American Lung Association. All you have to do is call them back and the menu lets you remove your number from their list.
Under HIPAA rules on privacy (http://www.hhs.gov/ocr/privacy/hipaa/administrative/privacyrule/), hospitals cannot release private patient information. But if you have been treated for lung problems, there are dozens of other ways they can obtain your information. If you receive drugs for your condition, the drug company may compile and sell a list of such individuals from the pharmacy records that are kept in case of recalls. If your physician has his/her records maintained or completed (such as transcription of dictation) through any of the multitude of off-shore companies, those companies can and do "data harvest" from those records and sell those lists. (Your physician of course will be told that this doesn't happen! But there is no way to track it and it isn't illegal in those countries.) Perhaps you sent for a magazine or information on the condition. On and on.
