VoIP was dragged kicking and screaming into E911, so now they charge
extra and are quite clear about it.  My VoIP provider regularly
reminds me to update my 9-1-1 address, but since I don't have to pay
the 9-1-1 fee if I lie and say I'm outside North America, that's what
I do.  Since I also have a classic CO-powered copper landline (1/4
mile from the CO, no concentrators or repeaters) and a couple of cell
phones, I think we're covered.
