Questions about Alcatel T56

@Digitec. The filter function for telephones has two shortcomings: A) You can select "landline" but not "wired" - not every landline phone has a cable. B) In the filter there is the item "Clip" (= display of the telephone number). However, if you select "Clip", there are very few hits, although there are many telephones with an LCD display, all of which show the caller's telephone number without exception. Instead of "Clip", the filter item should be called "Display", because perhaps many manufacturers no longer call this function "Clip" (?). Thank you and best regards
