Blocking all unknown numbers is fairly standard.

Defining a silent ringtone by default, and a non-silent one for your contacts, is another.

Better management tools on phones themselves would be a bonus.

My phone is always on silent. Unless I am expecting a very important call. I prefer not to be notified. I am even tempted to invest some time and write an app that does exactly what I want -> Reject all calls from unknown numbers.

I've opted out of PSTN entirely, for the past few years.

[madiathomas]

That's my goal too.

[dredmorbius]

If you don't mind my asking, why?

I've identified a few possibly concerns:

- Privacy.

- Avoiding distraction.

- Cost.

Others?

[madiathomas]

To avoid distraction. Majority of calls I received from landline numbers, are from robocalls.

Thanks, interesting, and understandable.
