Call Filter is a Powerful yet simple to use application that allows the user to send busy signals to incoming callers. To use this application, simply build a list of numbers that you would like to send busy signals to. That's it!. Now every time there is an incoming call made to your phone, our application will scan the incoming number and send a busy signal or let the phone ring incase the incoming number is not present in the blacklist. We have taken this application one-step further by integrating several advanced features such as: Sequence of Number Integration: With this feature the user will be able to reject all calls that contain a sequence of numbers. 'Reject All' Mode: This mode will send busy signals to all incoming callers. This feature will assure that none of the calls get through. White list: Enables the user to give some phone numbers priority by adding their numbers to the white lists. The phone numbers in the white list will be accepted at times, even in the 'Reject All' Mode. Contacts: Add groups and/or from phonebook to black or white lists. After Installation the application runs quietly in the background mode without disturbing any functionalities of the phone. Best of all, the user does not need to activate this product manually every time the phone starts. Call Filter like all other Aglaya Products is automatically started when the phone is switched on without any user interaction. The application is simple to use. With easy User Interfaces and menus, running this application is a breeze. The user will be able to create a Blacklist of users that are to be blocked. You can add users directly from the Address Book or type in their numbers manually. You have complete control of the lists at all times.
