'a list?' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'summon to read out' is the wordplay.
'summon' becomes 'call' (I've seen this before).
'to' says to put letters next to each other.
'read out' becomes 'over' (I am not sure about this - if you are sure you should believe this answer much more).
'call'+'over'='CALL OVER'
