Calls: 'Son, peel the bananas!' (10)

I believe the answer is:

telephones

'calls' is the definition.
('telephone' can be a synonym of 'call')

'son peel the bananas' is the wordplay.
'bananas' is an anagram indicator (informal term for mad).
'son'+'peel'+'the'='sonpeelthe'
'sonpeelthe' with letters rearranged gives 'TELEPHONES'.

(Another definition for telephones that I've seen is " Calls".)

I've seen this clue in The Telegraph.
