Hello,
For those interested, I added a piece to mod lcr wiki. It makes sorting
/ routing logic better than default logic:
http://wiki.freeswitch.org/wiki/Mod_lcr#Custom_SQL_with_sub-query_-_for_real-life_ratesheet_complexities
Why it helps:
Rates rates can often be given both on per-NPA or per-NPANXX level
depending on the carrier and on the NPA. Moreover, some carriers may
have NPANXX rate lower than the corresponding NPA rate, while others
will have it inverse. Neither simple ORDER BY rate, prefix; nor ORDER BY
prefix, rate; give the truly cheapest route. The LCR logic should be
two-step process to accommodate this.
Cheers,

Unless I misunderstand what you're saying, this is what the
reorder_by_rate param does.
