Number blocking works very well here. The reason being to be able to
white-list as well.

I block the zones 1,2,5,6,7 and 8.

For zone 1 there exists a lengthy whitelist because our family has a
couple of friends and relatives in the USA. My wife is American and she
grew up there.

In the zones 3 and 4 I figured out in a couple of cases which number
blocks are problematic or which countries. The UK is blocked and only a
couple of numbers whitelisted because the UK is an important source of
international phone-spam.

At the national level 500 numbers after the area codes are usually the
source of spam calls by call centers or organisations doing "opinion polls".

The efforts of the provider and the tools he offers and my extensive
filtering have led to an almost spam free LL. And the policy is not to
answer calls with unknown numbers and let them talk to the voice box.

Fact is that our private calls are done with our mobiles most of the time.
