[VoiceOps] Interstate vs. intrastate rates

[Alex Balashov]

Traditionally, in our trunk routing and rating system, we deal with 
intra- and inter-state rates by mapping the ANI and the DNIS to regions, 
which in turn have prefix lists associated with them.  If the regions 
match, it's an intrastate call.  If they don't match, it's interstate. 
If one or both of them cannot be mapped to a region, our system allows 
you to choose default inter- or intra- treatment in such situations.

Recently, a customer approached us with a rate deck, from one of their 
wholesale termination vendors, that had an additional "indeterminate" 
rate column on it.  The rates didn't seem to differ substantially from 
the intrastate rates (which tend to be higher), but they were different.

Is this a new trend?   Is this something we need to support to be on the 
ball?  Or is this an exotic vendor?

Thanks,
