call filter feature: could user define call deny notification ?

a number is defined call filter, when it call my phone, it first connect and then give a system notify( in china) such as “your called number is busy now, please try again later”. it juse like i hand up the coming calling, I think is not friendly. how can i define(fake) different deny notification, such as “dododo” , or “can’t connect the number”, “your called number is not in serving cell” and so on.
i konw lots of other apps have this feature.

Hi,

there are currently no options regarding what to do with the blocked call, sorry.
