[Freeswitch-users] Hello from Scotland - Python - error importing module

[Traun Leyden]

You'll want to change your dialplan to

<extension name="500">
      <condition field="destination_number" expression="^500$">
        <action application="python" data="test"/>
      </condition>
    </extension>

and make sure you put your test.py script somewhere on the PYTHONPATH by:

1. Copying or symlinking it to the appropriate site-packages directory

2. Copying test.py to /tmp, adding /tmp to your PYTHONPATH environment
variable, and restarting freeswitch so it has the correct PYTHONPATH.
(replace /tmp with your favorite directory)

See http://wiki.freeswitch.org/wiki/Mod_python#PYTHONPATH for more details.

> Initially speed of development / application tuning for new proof of

> To test this out I have set up a box running CentOS 5, built Freeswitch
