Called my cell, no message

Called my cell phone at 9:09.  No message.

Called cell. Didn't leave a message.

Same deal as previous posters: called my cell phone and left no message. I do not answer calls unless the caller is identied and known to me. I suspect they are illegal telemarketers (I am in both federal and state Do Not Call lists.) or scammers.

This number calls my cell phone and leaves no message. I will not answer it because I do not know the caller.
