Silence Unsolicited Calls

Tired of getting spam or unsolicited calls at any time ?
This app uses the digits of the incoming number to determine if the ringtone needs to be silenced. It will check for any incoming call if the number matches a set of criteria, and silence the ringtone or let the phone ring. You define the numbers you always want to silence, and the numbers you always want to ring normally.
Of course, if the numbers are present in your address book, they wont be silenced. You also define if you want private and unknown numbers to ring normally or to be silenced.
In the criteria, you simply define the first characters to get a match. So, if you accept +33 and silence +, all international calls, except those coming from France, will be silenced.
