Jumped at odds and made a phone call (6)
I believe the answer is:
sprang
'jumped' is the definition.
(springing is a kind of jumping)
'odds and made a phone call' is the wordplay.
'odds' becomes 'sp' (betting abbreviation for starting price).
'and' says to put letters next to each other.
'made a phone call' becomes 'rang' (I've seen this before).
'sp'+'rang'='SPRANG'
'at' is the link.
(Other definitions for sprang that I've seen before include "bounced" , "Leapt foward" , "Bounded forward" , "freed prisoner" , "released from prison" .)
