Mobile App for IOs & Android

A mobile app that intercepts calls from phone numbers not recognized in contact list.

If a call is from a phone number in contact list app will not activate and call will go through as normal.

When a call is made from a phone number not recognized in contact list the mobile app will activate by intercepting and answering the call and prompt the caller to dial a random series of numbers, a digital captcha, or a code, to gain access to the person they are calling.

While this is happening the app will notify the person who is being called of the unknown number/caller.

If the caller does not enter the correct numbers when prompted the app will automatically disconnect the call.

If the caller enters the numbers, or code, correctly the app will then notify the person being called and the person will have the option to accept or decline.

A premium version will do exactly the same, but after the app prompts the caller to enter the code, and the code is entered correctly, the caller will then be asked by an automated message to "please state who you are, who you are trying to reach and the nature of your call, and we will relay your message now".

The person being called will then immediately be allowed to here the voice message from the caller, who they are, who they are trying to reach, and why, and will have the option of accepting or declining the call.
