Actually, there's quite a few vendors already doing this. One that I found to be quite impressive was vonage.com. They've got it figured out. I'm actually testing out their service for long distance service at my office. They give you an ATA186 with the service, which I've connected to an FXO port off my CCM system and setup least cost routing for long distance service.
Actually, they had a deal on amazon where you purchase the ATA186 for $100 and they give you two months of their $40 unlimited long distance service for free. Heck, it would cost me $100 to buy an ATA186 and I get two months of free long distance included...what a deal. Quality is remarkably good. It hardly ever hiccups at all, which is surprising since our Internet connection gets hammered pretty often. Anyway, I've been doing IP phones in production for several years and this is by far the coolest VoIP service I personally have seen. Vance ps. Oh yea, 1) Vonage runs SIP. 2) When I'm on the road and run my softphone (CCM), I do notice degredation when the latency gets up to a couple hundred msec. Doesn't get unacceptable to me until about 600 - 1000 and then I start noticing dropouts.
