After a long day at work or in the middle of the night, the last thing you want to hear is the loud ring of the telephone and at the other end of the line - phone harassment. It could be the sound of heavy breathing, the deep voice taunting you with explicit language, or a scary stretch of silence. Some people may experience the annoyance of a prank call at least one time in their life, but there are those who are unfortunate enough to encounter ongoing phone harassment that has the potential to get quite out of hand.
