Call round (4)

I believe the answer is:

ring

I believe this clue is a double definition.

'call' is the first definition.
(telephone call)

'round' is the second definition.
(synonyms)

(Other definitions for ring that I've seen before include "Contact" , "Circle that's square for boxers" , "Hoop" , "Marriage token" , "resonant sound" .)

I've seen this clue in the Financial Times, The Globe and Mail, The Independent, The Guardian and The Times.
