on my 6 year old phone i list all my contacts and their name, in tools i select annouce their name when i get a call , so when i get a call i know who it is.
Some i even have their picture displayed.
when i get a non contact call it announce just a phone number and i never answer that. The phone is a flip that was set to answer when
i flipped the phone open which i changed to answer only when i press send.
