Add a subscriber to an emergency with waiting sounds?

Question

Android

I somehow formulated it funny ...
I want to make a person ignore the phone. But there is a nuance: when you call me, he will constantly hear beeps like "busy". Is it possible to make the beeps long, as if I simply do not pick up the phone? Maybe there are some applications.

Answer 1

Make a silent call to him. (record "silence" and put on it)
