  It would appear to be a bug in SER.

  Yes.

  What they do for something inside of SER is their business.  When
they generate RADIUS packets, they should follow RADIUS standards and
interoperability.  The expectation, as you said, is that the
Calling/Called-Station-Id doesn't change during a session.  If it
does, it's a bug and they should fix it.

  I would say it's not a FreeRADIUS issue.  Rather, just inject the
records into SQL as-is, and write a script to post-process the SQL
database, to fix the records.
