# Description
We installed kamailio from the ubuntu package manager along with several of the modules, including `kamailio-python3-modules`, which gives us the app_python3 module.
We edited the default, provided config to add the lines
``` loadmodule "app_python3.so" ... modparam("app_python3", "load", "my_cool_python_file.py") ``` Restarted kamailio and found the log messages below.

Please try to use the latest 5.3.6 version or 5.4.2 - there might be some bugfixes related to this module. You can use the project repository at deb.kamailio.org
Upgraded to 5.4.2 from deb.kamailio.org, and that seemed to do the trick
Closed #2534.
Thanks for the feedback, great.
