Hi New here - please be gentle I have an iPhone 5s with latest IOS - 7.0.4. I have a Blocked caller (one person, two numbers, both set to Blocked) that actually made the phone ring just now. Is this a known error/bug/hack? I've unblocked and reblocked the caller numbers (not called me back yet, to test) and I have called my phone from a landline, blocked that and it worked. Has someone found a way around making a successful call from a blocked number?
