Ghost Call

A ghost call or phantom call is a telephone call for which, when the recipient of the call answers, there is no one on the other end of the call. Ghost calls differ to silent calls which tend to be from telemarking organisations with no agents available to speak at the time an automated call has been placed. There have also been documented cases of people being called by deceased loved ones.
