[maanusman]

Hello sir, i m searching android app for internet call block. i have a problem please send some solution to me. i live in pakistan and my using htc one x with warid network. some one call me from manilla philphine and my phone shows local number. i use call block app and it is not possible for me to block every time new number. then i decide to allow phone book entries only so that every call block exept phone book entries but know no one contact me because only phone book entries allow.
kindly give some solution i want to block only international calls who have shows local number.. please.
