I'm setting up a Raspberry Pi 3 B as an SBC, but not much of an expert with Linux yet. I was able to get everything setup per these instructions http://www.3cx.com/docs/3cx-sbc-raspberry-pi/, but I made a mistake on in the IP address, so wanted to change it. I'm not able to modify the 3cxsbc.conf file and to top that I can't seem to kill the 3cxsbc process even with elevated kill commands assuming the app is locking the config file. Not sure if it's relevant, but I'm SSH'ing in to the CLI as a pi user and trying to manage it that way. Is there more detail somewhere about using 3CXs SBC app on a Raspberry Pi? I'm also not sure if I've got the latest version, since it looks like there's some disconnect on the 3CX website's instructions for the Raspberry Pi.
