Can I edit sip.conf?

Good Morning,
I want to add few lines to the sip.conf (like permit/deny) but the header of the file says not to edit this file manually because it used by freepbx.

What can I do? I don’t find permit/deny options in the freepbx, Should I edit some other file? or just to ignore the header warning?

Thanks!

the best place to set things are in the extension/device options if present, and in the sipsettings module.

If you don’t have permit/deny, which is usually for devices/extensions, it sounds like you might need to upgrade your version of FreePBX???

you can edit any *_custom.conf file and those get included…
