I would be interested, however there is already a perl script that does
exactly that called h323detail2db.pl in src/billing/
It is specific to Cisco h323 VSA records and my pqsl-voip schema but it
can be trivially changed to work with "standard" records.
If you give me a look at your script, maybe we can combine our work.

I think this is much pretty script - it's easy to configure to different
scheme.
It's only have no any preparations for open Cisco-AVPair since my
FR parse all needed attributes self, but it can be easily done...
