I gave this a try and it works for me. One thing I noticed is that if you
run a call asynchronously, the final result ends up under the source block
instead of the call.  In the example below both RESULTS were written after
I ran the call.

    #+name: test-call
    #+begin_src python :results output
      import time
      time.sleep(5)
      print("done")
    #+end_src

    #+RESULTS: test-call
    : done

    #+call: test-call() :session :async

    #+RESULTS:
    : 70e844920752b3411170716dc450c50f
