 A2Billing doesn't do that. A2Billing in fact has a lot of shortcomings one
of which is this exact issue.

I would suggest running rate sheets against each other for finding true LCR
and then only uploading the rates that are cheaper into the system. In most
cases there are not such high differences but if there are then this is the
only way. I know rate normalization talk comes up all the time on
FreeSwitch Freenode channel and it probably does on OpenSIPs as well. Check
there for some good advice.
