Tape of call capturing point at which company doctor returned (9)
I believe the answer is:
recording
'tape of call capturing point at which company doctor returned' is the definition.
'recording' can be an answer for 'tape' (I've seen this before). I'm not sure about the remainder of the definition.
'tape of call' is the wordplay.
'tape' becomes 'record' ('record' can be a synonym of 'tape').
'of call' becomes 'ing' (I can't explain this - if you can you should believe this answer much more).
'record'+'ing'='RECORDING'
(Other definitions for recording that I've seen before include "Tape" , "Eg, something on CD" , "Writing down or registering electronically" , "Taping" , "Transcription" .)
