Conference centre shunned by Herb (6)

I believe the answer is:

parley

I'm a little stuck... Click here to teach me more about this clue!

'conference' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for parley that I've seen before include "Speak with another" , "Dialogue between enemies" , "Conference of enemies" , "Confer" , "discussion" .)

I've seen this clue in The Independent.
