voicemail Error importing module
tjaracastjaracas 1238180314|%e %b %Y, %H:%M %Z|agohover

Hello, After a call is going into voicemail using the standard xml template i receive the following error in freeswitch and wikipbx log. The export python settings are in place. PLeae advice if you have an idea what might be causing this situation.

My dialplan looks like this
<action application="set" data="call_timeout=30"/>
<action application="set" data="continue_on_fail=true"/>
<action application="set" data="hangup_after_bridge=true"/>
<action application="bridge" data="sofia/arubel/7050%ipaddress"/>
<action application="set" data="vmaction=record"/>
<action application="python" data="wikipbx.ivr.voicemail"/>

the freeswitchlog shows this

So, do you have Django installed as described in the installation manual?

What seems to be happening is that the IVR executing under freeswitch cannot find the django library python code. This could happen if Django was not installed correctly (or not at all), or if Django was installed to a different version of python than the one freeswitch is using.

Please do the following:

1. Run "python" from the command line and post the python version

2. Enter

from django.db import models

on the python shell and post the output

3. Copy and paste the /usr/src/freeswitch_xxx/src/mod/languages/mod_python/Makefile file to your post

Here is the output of themakefile

I already see where it is going wrong.

I can either change the 2.4 value in the makefile or add the /correct path to site-packages in my PYTHONPATH. I did last and all is working fine now. Thanks.

I've had this issue before. I think that the problem is caused by invalid sequence of actions in wikipbx install manual: it tells you first to bootstrap & configure freeswitch and later to edit modules.conf. But that means that the modules.conf has default values when configure script is run, so when you build freeswitch with mod_python enabled it uses default values instead of the ones it can detect on your system.

I think the sequence of events is correct in the manual. My only guess is that is looked for a previously installed 2.4 python version on the system in stead of the newer 2.6 version. I dont think that the sequence of events in the manual is wrong. If you add an additional module to freeswitch you just can make it in the source dir and adding it to modules.conf.xml. No deed to reconfigure the complete application. So somewhere it took the incorrect version for python and put this in the makefile.

Interesting, I've just checked and looks like python is detected correctly even if it's disabled in modules.conf. So my guess was wrong, although I've experienced such problem some time ago. Can you confirm that running "python -V" doesn't show that you have python 2.4 as default?

Apparently, it should be possible to avoid such error by forcing FS to use an exact version of python by specifying —with-python=/path/to/python/executable flag to configure script.
