Good Addon. Works!
For Europe (Germany) you should set the Number Rules in Settings. I did set:
0)xx xxxxxx
0)xxx xxxxxx
0)xxxx xxxxxx
0)xxxx xxxxxxx
0049xxxxxxxxxx
0049xxxxxxxxxxx
(xxx)xxx-xx-xx
xxx / xx xxx xxx
xxx / xxxx xxxx
xxx / xxx xxx xxx
xxx xx xxx xxx
xxx xxx xxx xxx
xxx xxxx xxxx
xxx xxxxxx
xxx xxxxxxx
xxx xxxxxxxx
xxx xxxxxxxxx

This needs to be completed to work on all numbers. I just started.

To the developer: Good would be someting like a placeholder* like xxx x* to get all Numbers with no matter how many digits a number is long.

Tanks for providing this Addon!
