I often get calls from unknown numbers, e.g. unwanted commercials, ping calls, people who dialled the wrong number and so on. Extra unpleasing is, if this happens at 3 am.
So I would like to have a filter rule for numbers, the telephone will not ring, and please also not turns on the display.
Suggestions for such a filter / filter rules:
Numbers not in the phonebook
Country codes of some foreign countries (+ list of country codes)
Country codes of all foreign countries
Special numbers (+ list of numbers)
Anonymous calls, that do not send the callers number
Every item with a switch on/off and a general switch to enable/disable the filtering.
EDIT: plus an extra list of the filtered calls, to check them later.
