  Fix a bug where the recorded privacy introduction file would not get removed if the caller hung up
  while the called party had not yet answered.
  
  This was fixed by introducing an argument to the 'n' option which, when enabled, removes the introduction
  file under all scenarios. This was done to preserve the behavior that has existed for quite some time.
