  If there's a User-Name, it should be sent in accounting packets.  The same goes for Calling-Station-ID, which is usually the MAC address.

  Doing anything else is severely unfriendly to every other RADIUS system.

  I'm not sure I understand that.  CUI is sent by the RADIUS server to the NAS.  The NAS *never* creates a CUI and sends it to the server.  See RFC 4372 for details.

Obviously in this scenario it won't change

  That doesn't make sense.

  If the RADIUS server sends a Framed-IP-Address to the NAS, the NAS should echo it back in accounting packets.  If the Framed-IP-Address is changed in a CoA request, then the NAS should echo the *new* Framed-IP-Address in subsequent accounting requests.

  They can ask RADIUS people for help.


  It's better to fix things in the engineering stage.  The alternative is to ship garbage, and then have the poor users wonder why the software isn't compatible with anything else.
