I tried both, and neither works. Here is an org file showing the
problem:

--8<---------------cut here---------------start------------->8---
#+name: testcall
#+BEGIN_SRC sh :exports none :results raw
echo "#+BEGIN_SRC emacs-lisp"
echo "(+ 1 2)"
echo "#+END_SRC"
#+END_SRC

Test fails:
#+call: testcall() :results raw

#+RESULTS:
#+BEGIN_SRC emacs-lisp
(+ 1 2)
#+END_SRC

Test fails:
#+call: testcall[:results replace]() :results raw

#+RESULTS:
#+BEGIN_SRC emacs-lisp
(+ 1 2)
#+END_SRC

Test fails:
#+call: testcall() :results raw replace

#+RESULTS:
#+BEGIN_SRC emacs-lisp
(+ 1 2)
#+END_SRC

Test succeeds (results not already in the file):
#+call: testcall() :results raw
--8<---------------cut here---------------end--------------->8---

If you export this, you'll see that only the last call generates the
expected output.
