Get 2 or 3 calls a day for past month. Caller ID says call is from Boise (idaho)  I have never answered and always let answer machine get it. Usually they hang up before ans machine kicks on or a few seconds afterwards. They have never left a message. I suspect it MIGHT some sort of collections agency since my phone number is tied in by mistake to someone who I think  had a bad debt problem. I am not sure if it is a good idea to answer this call, as it may make it worse. Not a major problem yet. Suprised it is not in the database yet
