that was year 2002. things have improved a lot since then in ser and
now number of db queries can be very few.

you don't need to implement your own modules. both radius_www_authorize and
radius_does_uri_exists can now store any number of attributes into
AVPs as side effect of the call.

also call forwarding attributes can be returned by adius_does_uri_exists

there is really nothing special. for example, if called uri has
unconditional forwarding on, radius would return the new uri as value of
"cf_unc" attribute, which you can then test in your ser.cfg.
