I've had a VOIP phone for years but here's a correction about cell phones. Good in cities crappy up in northern Ontario. When I go visit my folks, I have to leave their house to get coverage, lots of the Hwy up North is not covered so don't think a cell phone is going to save your life when your travelling because it isn't necessarily true.
Now Hwy coverage is actually pretty good but in the woods just forget it. Maybe if you go to a highest hill. I even had this problem in Acton visiting my friend at a trailer park and that's not even an hour out of the city.
And here's the lawsuit over 911 coverage even Norther lol I made a new word.

Huh? I'm saying cell phones offer MORE coverage than a landline...
Your landline isn't going to call 911 from the HWY up north either! I live much further north than most people (we still have snow, my heat is still on) and I get cell phone coverage while I snowmobile
If you go out of cell phone coverage, you'd obviously need sat comms or a personal emergency transponder
For those saying VoIP is bad quality, the problem is the technology is young and a lot of people are using crappy equipment and don't know how to set it up
With a decent internet connection, router that is designed for VoIP (prioritizes voice with QoS) and a good Mic it sounds perfectly fine. The Linksys SPA2102 is a great piece of kit you won't find in a big box store
High speed internet has more than enough bandwidth to carry good quality voice. Digital voice plans that cable companies sell now Are VoIP
NORAD has been using VoIP for years...
The only reason it's slow to catch on, is the big companies are soaking you for every last penny for as long as they can by charging you twice for data transfer
