I know there are certain areas around the country that are not portable for a few reasons. One reason is when they are served off of a remote switch, they have elaborate e911 trunking schemes and must remain on that switch to properly function in an isolation-type scenario.

?Aren't 95%+ rate centres pooled these days? If so, they'd still have LRNs, since LRN-guided routing is a requirement of pooling. So, who still has non-pooled 10K blocks? Is that common in metro, or largely a trait of rural LECs?

NPAC has a service type field that indicates wireless/wireline. That doesn't solve for native numbers though since they won't have LRN data since they don't have LRNs. I don't remember offhand if LERG has a wireless/wireline indication for a given [A]OCN or block.

If I were to offer this service or database access, I would start with my own local copy of NPAC that I'd update every X-minutes a day. This product is available now and has been for a while. This is the only sure-way, I know of, to have the most accurate data to work from.

Right now they are considering abandoning all of their auto/predictive dialer software and going to manual dial for everything, because the list-scrubbing services have been shown to be inaccurate. There are extreme penalties for auto-dialing a cell phone, and "best effort" is NOT a defense to this, at all. For example, Gallup just settle a claim for $12M.
So they need a totally accurate way to prevent a cell phone call from originating from their dialer. The only thing I can think of is some sort of LRN dip + LRN-to-carrier-type response. One of their people talked to Neustar, but didn't get great answers because he doesn't really understand telephony. Before I get in touch with Neustar, I thought I'd see if people here have some ideas.
If you provide a commercial product for this, please feel free to tell me so on or off list, the customer is willing to pay for the service and we're open to all options. I don't have a budget number yet but manual dialing is going to cost them quite a bit for some types of studies.
