I get two to three a day.

The numbers are spoofed so that many appear to come from my local area code so blocking them doesn't work. They rarely come from the same number twice.

Got a spam blocking app. That only catches about one in five numbers.

Finally I went to the trouble of Whitelisting my contact list. Here's how you do that.

1.Get a silent ring tone.

2.Set the silent ring tone as default.

3.Set no vibrate as default.

Now the hard part....

4.Go through your contact list and set each contact its own ring tone other than default.

There Whitelisted!

Problem....If someone from a business says that they will call when, for instance, a product comes in. You have to make sure that the number that they will call from is in your contact list otherwise you'll never get the call.

Second problem....when I'm in the car the car's bluetooth connection has its own ringtone so the spam comes through although without contact information so you'll know what it is.

I have my iPhone Do Not Disturb settings set to manual. No ring tone, no vibrate.

I’ll still see the spam calls listed in my call history. I have the option to block them, but as you say, the spoofed calls will continue using other local numbers.

People/businesses I choose to hear from are set as favorites and allowed to ring through.

NICE!

Since I learned they do not call if you won the lotto and you must buy a ticket first...

Turned off ALL notifications, not concerned about the latest anything from The Goog. Ringer off.

If I see the screen flashing I might look, a blue LED blinks for incoming text. With the phone face down, as good as off.

But I will move to your method for the wife and kids.
Good idea.

I’ve done that. It took some time but was well worth it.

I agree your method will work to stop spam calls from getting through, I see two issues with it that perhaps you've already addressed that I didn't see in your method:

1. Won't spam calls get through to your voicemail anyway?
2. It seems like an awful lot of maintenance if one has a large contacts list to set custom ring tones for those contacts.

What am I missing in your solution?

BTW, I use "Should I Answer?" and "Mr. Number" on my Samsung Galaxy S9 to deal with spam calls. I don't recall the last time a spam call got through. It uses Social Media and user submissions of bad numbers and/or bad prefixes to block spam. I think it works great.

Merry Christmas to you and yours!
