    I am getting “Unknown” calls from oriental callers faking a message from my computer. The problem is when the call comes in: No accept or reject shows on the screen. So I have to let it ring, After they hangup. When I try to block the call there is no number so nothing shows for blocking, and I guess ios 10 doesn’t have a way of blocking UNKNOWN callers. No I can’t use contacts only because I get legitimate calls from people not in my contacts. I have searched the ios apps and there is nothing free to solve this problem. Any help will be appreciated.
