Do call (8)

I believe the answer is:

occasion

I believe this clue is a double definition.

'do' is the first definition.
(I know that occasion is a type of do)

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

(Other definitions for occasion that I've seen before include "Make happen" , "Give rise to" , "Opportunity" , "Time of (maybe special) event" , "Special event; reason" .)

I've seen this clue in The Times and The Sun.
