We also just received a dead call from this number. They called, we did not recognize number on caller I.D. so we did not respond to call. They disconnected call once it was time for them to leave a message. We rang them back three times, it just rang and rang and rang, eventually going to a busy signal than disconnecting. This is second day in a row from this number, if it continues they will be added to block list.
A call from CUIAB was answered by me and the call sounded like he was calling from a call center. He asked for either of my parents. I told him they weren't available and asked if he would like to leave a message he got a little flustered and said no it's okay I'll call back before I could say anything else he hung up. I figure its a sales call
