it state  , Delta three on the caller  ID

They ALWAYS call and you say hello, then they always hang up. What a waste of time, these people need real jobs!!

They keep call my house.  I inquired about magic jack on my computer and since then I have been getting calls from delta three and qwest.  What a pain!  They get a message on my machine if they are a solicitator that I am on a no call list and do not call back, but they seem to ignore that fact.
