Some robo dialing scam, sounds like their recording is busted.  I put them on speaker phone and someone live got on and said please don't put the call on speaker!  As I started to talk to them off speaker it went back to the broken recording.   Lol.  They can't sell me what I can't understand...  They call several times a month from various phone numbers around the country.  The majority thus far have numbers that say Texas, but that's probably a spoofed number anyways.  You can't call the number back, says the number you have dialed is incorrect, but it rings a while first.
