Calls come in from this number day in and day out. There is never a specific time. Since there is no idea where this number comes from or whom, no one picks up to answer the call, opting for the answering machine to do so. Albeit, the caller never leaves a message ... but often will call back right away, wait a few hours or call a few days later. The only time the number did not call right back was when someone answered the call to prevent the annoying ringing, then hung up immediately. Yes, whomever is calling lets the phone ring and ring so much so that not only did answering maching have to be connected but the pick-up ring on the answering machine had to be adjusted to one ring. so now all calls are screened.
