Counter talk (8)
I believe the answer is:
converse
I believe this clue is a double definition.
'counter' is the first definition.
(thesaurus)
'talk' is the second definition.
(conversing is a kind of talking)
(Other definitions for converse that I've seen before include "Have a chat, being contrary" , "Talk together" , "Communicate with" , "Opposing" , "take part in discussion" .)
