Somewhere I swear I saw it!

I am looking for a OSS Endpoint manager in Freepbx user guide. I am sure I saw it somewhere in the last month or so but can’t find it again.

Can someone provide a link or directions – Thanks

I am looking for a simple tutorial on how to use it to provision my phones. Also, a way to add a phone that is not yet supported.
