'to call on' is the definition.
I know nothing about this answer so I can't tell whether this works.

'wakens up and takes' is the wordplay.
'wakens up' becomes 'round' (I can't explain this - if you can you should believe this answer much more).
'and' is a charade indicator (letters next to each other).
'takes' becomes 'brings' ('bring' can be a synonym of 'take').
'round' put after 'brings' is 'BRINGS ROUND'.

'with' is the link.
