this number calls with an automated voice saying I need to call back to avoid a law suit...so annoying.

The voice mail said to avoid a law suit from the I.R.S.  I need to call back immediately.   Seems like as long as I know the number and the fraudulent call.  Time to prosecute and start litigation.

recorded message on answering machine said: call back  to avoid a lawsuit,  I and my property were being monitored, legal action will be taken if you do not return this call.  Arrest warrant will be issued.
