Yeah, same idea here with voip.ms. The caller-name lookup fee of $0.015 is charged per-call, if enabled on the account (ordinary calling-number display is *free*). Apparently that's close to what it costs them to do the lookup, so they just pass it on.

They do say they plan to implement caching and stuff at some point, which would reduce those charges. I'm not counting on that actually happening, but.. whatever.

I chose voip.ms because they're Montreal-based, with PoP in Montreal and Toronto, plus the UK and a bunch of USA locations. Two of those are relatively close to Ottawa (here) as far as pings go.

E911 setup was also a breeze. For us Canucks, that's an extra USD$1.50/month drawn from the prepaid funds.

Cheers
