Emergency call about right types (5)
I believe the answer is:
sorts
'types' is the definition.
(I've seen this before)
'emergency call about right' is the wordplay.
'emergency call' becomes 'SOS'.
'about' indicates putting letters inside.
'right' becomes 'rt' ().
'sos' going around 'rt' is 'SORTS'.
(Other definitions for sorts that I've seen before include "classes" , "Out of this is unhappy" , "Arranges in correct or desired sequence" , "Systematically arranges" , "Segregates items into groups" .)
