Apple blocks this caller number from hearing what the other party hears

If the iPhone blocks an incoming call, the other party will hear "Hello, the number you dialed is currently on a call, please call again later."

When an Apple mobile phone user sets the phone number of a contact on the phone to "block incoming calls", if the phone number calls his or her phone again, there will be two situations:

1. When the user's mobile phone is turned on, the Apple mobile phone will automatically identify the incoming call. After identifying it as "blocking the call", it will automatically hang up the call and prompt the other party "Sorry, the number you dialed is currently on a call. Please wait." Dial again later.”

2. When the user's mobile phone is turned off, the other party's mobile phone will have a voice prompt of "Hello, the number you dialed has been turned off."
