Having this strange issue that when I receive a phonecall, the number which is displayed misses the first digit.
In my case the incoming phonenumbers should have a leading zero, but this is missing.
So, if someone calls me with telephonenumber 0123456789, only 123456789 is being displayed.
This makes it impossible to return a call easily.
I checked several settings but have no idea what causes this.
Does somebody have a clue what this can be?
