install fusionpbx again on raspbian-buster-lite ( released on July 10,2019). No error was reported during installing, extension could be registered quickly. still works well after reboot. seems Fusionpbx / freeswitch has better support for raspberry pi or debian 10 than before. it was nightmare to install fusionpbx on raspbian/debian 9
