I usually just let this go to voicemail and have never received a message. Today, I answered. At first it started out like most telemarketing calls, I said Hello twice, heard an audible click, what sounded like a call transfer sound, then was disconnected..
I've been applying to jobs, so never know if one of these numbers could actually be someone wanting to call and interview me. So very annoying to be constantly answering my phone to nothingness! I was at a coffee shop recently and they were getting 10-20 calls a day from numbers outside of the state, who would hang up on them! I can't imagine that many people are mis-dialing and not saying "Sorry"
