2 calls this morning.  No message left either time.

call - picked up without saying anything - then dial tone. will block

Picked up the call without saying a word and they hung up. I called back from a work phone number and an automated voice says "Press any number to be taken off the list. It may take 24 hours."

Called and left no message.

Automated dialer calling numbers on the DNC list. Block them as I now have.
