I got the same message as Tekkub. If you really want to mess with them push the pound or star key over and over. It messes with most automated systems. This one just kept saying "hello, hello, hello" over and over :) The best one was when my son was a teenager and answered the phone and got a real person with some off phone company wanting us to change long distance carriers. All my son said was "I'm sorry we don't have a phone" and then hung up. They never called back. I don't get call backs after pushing the star or pound key either:) The phone ID said it was from Kearny, NJ
They call my cell and leave no msg. When I get these calls, if you have a phone that will do this - it works great - I tell it to divert the number to voice mail. Problem solved - it never rings and they never leave a msg!
