Calls for, at the hotel (5)
I believe the answer is:
pages
'calls for' is the definition.
(paging is a kind of calling for)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for pages that I've seen before include "Boy attendants" , "Hotel employees" , "Book leaves" , "Sheets of a book" , "Young attendants" .)
