How to block area code with Samsung A3 2016?

[Android Central Question]

Hello,

I want to block the area code for certain countries, because there are machines with so called ping calls that all ways have a different number and they call me (one ring).

I tried by blocking this so far, example guinea: (the last digits are always different)
+22455
+22455*
0022455
0022455*

A full number would be: 0022455315530 (ATTENTION DON'T CALL THIS, Expensive)

This can of course be tested with your local phone. So blocking my exact fixed network number works, however non of the above ways to block a range of numbers didn't work.

Help appreciated.

Settings/Call/Call rejection/Auto reject list/Create/Match criteria

Check "Starts with", then put in the beginning of the number.
