Annoying call, you are in trouble.Recently, a little contact is done with an SNS app, but the call of the phone that comes in without thinking about this situation is troublesome, but if the call sounds endlessly....It is reasonable to stop the calling sound itself.
To prevent the calling sound exclusive for the nuisance call, use the "unknown caller" supported by iOS 13 or later.This function determines the number that has never been received or transmitted, the number has been registered in the contact, or the number used in email or chat, and if it does not fall under any of them, the ringtone is silent.Connect to your answering machine (the incoming call history remains).To enable functions, turn on the switch on the "Settings" → "Telephone" → "Unknown callers" screen.
However, this function is not perfect.Because there are some disadvantages, it is necessary to use it after understanding the functions.
For example, if the person you call is a work person.It is common for companies/corporations to use multiple phone numbers, so it is not unusual to send them from different numbers from the ones written on the business card.If you enable "Unknown callers", there is a high possibility that you will be complained from your opponent that no matter how many times you call, you will lead to your answering machine.
Be careful when using an emergency phone.If you dial to the number 110 or 110, the "silence of unknown callers" will be invalid for 24 hours, so the calling sound of the annoying phone will be heard.
In addition, when the "silence of an unknown caller" is activated, you will receive a notification that you are not notified.When you see this notification, you should make sure that the number is from the nuisance call.
