im getting harassed from someone calling me from an "UNKNOWN" number. ive tried several free call filter applications available from the market, and although they work they dont work fast enough. they do send the call to voice mail, but only after my phone has already rang for about 1.5 seconds. i need an application that will dump the unknown call immediately, before it rings my phone at all. theres nothing quite like sitting in an hour long meeting and having your phone ring 30 times. i dont even mind paying for the application, i just dont want to pay for several before ifind one that works fast enough.
