The phone is ringing when I try that. The goal is to make it ring as lowe as possible, since I cannot change the phone profile. I run the code from a separate thread, and even tried to run it 2 seconds after it starts ringing (so I'm sure it's already ringing), but I cannot chamge it.
It must be possibile somehow since, for example, Black & White List Call Filter does just that...
Any suggestion is appreciated!
