Secure Calls

Secure Call is a solution that manages the users phone calls.
It is a solution that lets its subscribers manage their received calls by forcing the caller to enter a pin in order to have the ability to reach them.
The users have the ability to enable or disable different screening modes where they could use greylist so that the people trying to reach them will have to enter a specific pin code. Also, the user can use whitelist in order to skip the pin code entry. In addition, the user can also use blacklist in order to block incoming calls.
This customization is day/time based and grouped by single number, group of numbers and countries
