Best practices for Caller ID name to appear?

Internally, everything works fine. The phones display full Caller ID, but if I call an outside line then only the number gets displayed. Flowroute says the issue is with my PBX’s config. I’m using 13.0.6 with Asterisk 13. Is there something I need to enable or change to make Caller ID with name work externally?

Apparently this is a CNAM issue on Flowroute’s side. Nothing to do with Freepbx. Mods, please delete.
