Error when call a procedure that has a ref_cursor as out parameter

[skysegbr]

When I call the proc using strings it works:
result = cur.var(oracledb.CURSOR)
cur.callproc('MANAGEMENT.RET_EMAIL_RECEIVER', ['23', '1', '1', '1', result])

but when I send using integer it got stuck:
cur.callproc('MANAGEMENT.RET_EMAIL_RECEIVER', [23, 1, 1, 1 , result])

The procedure expects a number as in parameter.
Best regards.
