Attempting to follow the directions here:
The very first line, fwconsole setting FPBX_ARI_USER <(redacted)> returns this:
-bash: !P: event not found
Is this expected; can I ignore and continue?
Are you leaving the <> brackets in place? Those need to not be there.
It returns the same thing with or without brackets.
The issue was symbols in the randomly generated username and password. I replaced them with numbers and letters and got this done.
