Glad it works for you, I’m not allergic to the phone like seemingly everyone else so I strive to minimize phone tag BS and would rather answer the calls I get and filter out known spam, it’s not rocket science it’s probably only 2 lines of code in the phone app

If call is spam and ignore spam option enabled, send call to voicemail.

That’s it, a simple line of code. Just make the option selectable and it’s done.
