I believe that it's not so simple as TDM v IP as well. For example a cable operator using VoIP for local lines would not use the indeterminate rates because they have a valid ANI and is originating from a local carrier(ilec/clec whatever). The real problem comes in with pure VoIP originated services, however its trivial to mask the origin and assign a local USA number to calls. The grey area in my mind comes in when you've assigned a US # for those calls when they are clearly physically originating internationally but have a US identification inside the headers. Oh and Alex, I have seen a few us terminators offer that indeterminate rate deck. I think it's more of a CYA column combined with a bit of FUD to the originator so that the terminator can make a few hundredth's of a penny more per minute.

How would the TDM vs IP provenance of a call normally be determined, on a technical level?

From my experience the "indeterminate" rates are typically associated with the ability to determine if the origination point is a VoIP device or not. If the wholesale provider is unable to determine if the call was VoIP or TDM originated then the "indeterminate" rate would apply.

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,
