If the regions <br>match, it's an intrastate call. If they don't match, it's interstate. <br>If one or both of them cannot be mapped to a region, our system allows <br>you to choose default inter- or intra- treatment in such situations.<br><br>Recently, a customer approached us with a rate deck, from one of their <br>wholesale termination vendors, that had an additional "indeterminate" <br>rate column on it. The rates didn't seem to differ substantially from <br>the intrastate rates (which tend to be higher), but they were different.<br><br>Is this a new trend? Is this something we need to support to be on the <br>ball?
