Re: SIP connection
@Access1denied, to remove those settings you can either put them back to the original ones, or otherwise restore your configuration (if you take the backup before starting).
For example, in point 1 they help you identify a particular session-helper. Take a copy of that part of the config before you delete it, and replace it if you want to back-out. Do this by going to the appropriate section (config system session-helper, for example) and typing SHOW, which then allows you to copy the current settings out into a text file to simply replace them. You can use UNSET new settings that you add to remove them.
