Same. My phone only rings for friends and family, otherwise silent. Mostly on airplane mode or off.

I use voip + extension. If the person calling doesnt know it, they get 3 tries or a total of 10 seconds per try.

No extension = No voicemail. No Ring. Goodbye. Hang up. I Never have to acknowledge their existence unless I login and look at the logs.

Peace & Control has been restored to life and all is good.
