Face it, 7D is dead; and even if overlays had not arrived, cell phones would have killed it. Once you learn to think 10D, it's trivial.
Oh, you ignorant rednecks.* Even my cell phone has 7D dialing and it'll be a century before overlays arrive where I live. The reason that it makes sense for an ISP to warn its customers about surprise toll calls is that toll rates have gotten so low that for the most part, we don't worry about them. Due to the peculiar telegeography in my area, a 7D call within my area code could be local, intra-LATA toll, or inter-LATA toll. But the most expensive of those is 8 cents/min so for voice calls, I don't care, and I really appreciate not having the insane Texas plan where you have to memorize every single local prefix to be able to make a fripping phone call. Since ISP calls are long, even low toll rates add up, and that makes them unusual enough to be worth warning people. I really have to put some of the blame on telcos here. Every prefix in the country is assigned to a rate center, every phone has a set of rate centers that are local, and it's not rocket science to do the cross-product and tell people what numbers are local to them. CLEC or ILEC doesn't matter, nor does the location of the switch. I realize there are a few wacky prefixes that are local to the whole LATA, but they seem to be getting less common rather than more, and there's few enough of them to special case.
