ciscoaxl api python errors

Question

I am starting out working on looking into using Python for some Cisco CUCM automation. I found the plugin ciscoaxl here, I installed it and programed the following script:

from ciscoaxl import axl
cucm = "10.10.20.1"
username = "axlusr"
password = "password1"
version = "12.5"
ucm = axl(username, password, cucm, version)
for phone in ucm.get_phones():
    print(phone.name)

I am connected to Cisco's DevNET Sandbox and all the login and configuration for the AXL user appear to be correct, however I get the following output when I attempt to run the script:

Traceback (most recent call last):
  File "%home%\AppData\Local\Programs\Python\Python39\axl-test.py", line 7, in <module>
    for phone in ucm.get_phones():

    for each in inner(skip):

    return self.process_reply(client, operation_obj, response)
  File "%home%\AppData\Local\Programs\Python\Python39\lib\site-packages\zeep\wsdl\bindings\soap.py", line 195, in process_reply
    return self.process_error(doc, operation)

    raise Fault(
zeep.exceptions.Fault: Unknown fault occured

I have run it on Windows10 in an IDLE enviornment, from the Linux-Subsystem (Ubuntu 20.04) via python and ipython3.

Answer 1

After some additional research this is a know issue with CUCM 12.5. It should be fixed in CU1 see here: https://github.com/mvantellingen/python-zeep/issues/989

Answer 2

I still receive this error on 12.5.1.12900-115, but I receive it when I don't have the appropriate permissions. Fixing user permissions for AXL access resolves it.
