Introduction to the incoming call firewall function of iPhone

    Interception effect

When intercepting an incoming call, the first thing the other party hears is the user's busy tone, instead of first connecting and then hanging up. In this way, the other party can only judge that you are really on the call. Effectively avoid the embarrassment of rejecting calls from acquaintances.

      Scope of application

Block scam, harassment, promotional, one-ring and other spam calls. - Block any calls you don't want to receive, even from contacts in your address book. - One-click Do Not Disturb, reject calls from all contacts and allow calls from strangers. Best used during lunch break.

       Working principle

"Incoming Call Firewall" will hand over the blacklist list and your customized rules that need to be intercepted to the iOS system for safekeeping. When a call comes in, the system will determine whether to intercept it based on the rules you set. This APP does not directly participate in the call interception process. Therefore, you do not need to run the APP in the background, which will not consume more battery, and will not read any of your incoming and outgoing phone information, effectively protecting your mobile phone use and privacy security. .

       Pause and resume

The app supports pause and resume. If you don’t want to intercept for the time being, you can pause without deleting the blacklist rules and lists.

      Stable effect

This APP contains two relatively independent interception extensions, one basic interception and one rule interception, which are relatively independent and run stably.

       Privacy protection

The app is small in size and only does one thing: intercept spam calls! No internet connection is required, and no login is required. There are no other useless functions and no user information is collected, so you can use it with confidence.
