Unavailable.  I do not answer unavailable or any number I don't recognize or if no message is left.

Will not answer calls from unknown or numbers I do not recognize,  Anyone who wants/needs to speak to me should leave a message.

I am in agreement with fed up don't answer calls frome unknown callers leave a message or you will be speaking to the air.

caller id 'unavailable' , so I don't pick up and no voice mail left.  Nuisance robo-caller presumably, looking for live responders.

Showed UNKNOWN, but I didn't have glasses on and was expecting a call, so answered... Gave the name of some insurance company said they were recording the call and said they were calling for an "arthritis study". I said nothing other than hello and hung up when I heard what it was. If they are legitimate, they should at least have their company name on the caller ID.. Thus, I believe this to be a scam. Don't answer and definitely don't give them any information, and don't say "yes" to any question they might ask!! SCAMMER ALERT
