Blocking Spam Calls
I get a lot of unsolicited calls to my phone. I’ve registered with the national Do Not Call list, but robo callers only check this list after the call is placed, so I get two rings and then it stops. I’d like to send all calls from parties not in my contacts straight to ****, but I’ll settle for sending them to voicemail. Other than assigning a ring tone individually to each of my contacts, is there a way to block out callers who are not in my contact list? Thanks.
