Called and asked for husband by name and asked if he was available.  I said he was not and asked who was calling.  Dead silence for 10 seconds.  So I asked what his name is.  Dead silence for 5 more seconds.  I realized it was an automated call that has answers to certain questions but takes too long to search for the right answer.  The recording finally said he would call back another time.  I already blocked the number.  I tried to call the number back to see if I could tell who they are and it doesn't even ring.  I want THAT call blocker!
