Where one might ring to arrange a fight? (4,3)

'where one might' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.

'ring to arrange a fight?' is the wordplay.
I cannot quite see how this works, but
'ring' could be 'call' (synonyms) and 'call' is found in the answer.
'fight?' could be 'box' (boxing is a kind of fighting) and 'box' is present in the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?
