Incoming call firewall

Call Firewall, as the name suggests, is a phone and text message interception application. It can effectively intercept spam calls such as scams, harassment, promotions, ringtones, and blacklists. The working principle of the incoming call firewall to intercept calls is based on the newly opened feature CallKit of iOS 10. ====Intercepting effect====When intercepting an incoming call, the first thing the other party hears is the user's busy tone, instead of connecting first 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 spam calls such as scams, harassment, sales pitches, and one-shot 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. ====How it works==== "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, it will not consume more battery, and it will not read any of your incoming and outgoing phone information, effectively protecting your mobile phone use and privacy security. ====Pause and Resume====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. ====Convenient and fast====- Automatically detect the number on the clipboard and add it to the blocking blacklist. Copy the number you want to block in another App, such as a phone, and open this App. The App will automatically detect the number and prompt you whether to add it to the blocking blacklist. -Support single number addition. - Supports batch import of number segments into the interception list. For example, if you add the range: 4006650000 - 4006659999, you can intercept 10,000 numbers starting with 400. - Support batch import from computer. Paste the number list you copied from elsewhere into the specified web page of the browser and upload it. The App will automatically remove duplicates. ====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 will be collected, so you can use it with confidence. ====Usage Tips==== Since the call interception function of systems below iOS 10.1 is unstable, it is recommended that you upgrade the system to iOS 10.1 or higher. ====Get help====If you have any problems during use, please contact us: Website www.codefavor.com Email codefavorinc@gmail.com WeChat codefavor001
