I receive several from this number and a couple others that are recognized as home land lines still spam! I think it's a way to access your info when you answer a call with proper equipment they can determine where you are what kind of phone you're using etc. might sound paranoid but have you seen the spyware available to everyone for everyday use? Now it's advertised as a way to get ahead in business by finding out what customers are doing and where they are before you even approach them. If you're told that you can't get spyware on your phone you're being lied to, it's not the government you have to worry about it's these hard sell business and collection agencies and of course the everyday low life criminals who are pushing the stuff
The call came i they hung up before I could answer when I would answer they would hang up as soon as I would call the number back it says the person at extension 110 is not available please leave a voice message than the voice message says it is full and cannot receive voicemail definitely a spammer
