Changing to device and user option on new FreePBX installation

I have looked under settings and tools and cannot find where I have to change this

Go to the System Setup Section and you’ll see “User & Devices Mode”

Please note: Some of the settings are Read-only and or hidden so you may need to change some of the options at the top of the page to be able to see/modify these.

Try searching the forum. There are several recent discussions on the topic.

Pay attention to the 2.9 instructions through the entire page. No manual editing of files is necessary, that’s there for old installs.
