The above phone number calls day or night. It does not matter the time. I have done reverse look phone number, but unless you pay a fee or a membership fee more information other that the call is coming from Idao some where. The number never leaves a message. If the number is answered it hangs up as soon as you say "Hello."  Or When you call back it hangs-up or says "Wait for the next available representative."  I have waited up to  five minutes either the caller hangs up or I have hung up.
