Its a Canadian company, much more reliable, and your number is safer in Canada If you care about your carrier trying to play games and lock it down.
I have a UPS battery backup anyway for when the power is out for short term.
$29 for ATA
If you need to port your number One Time: $9.95
$4.95 + Tax per month.
With the 4 months free, this should be a no brainer for anyone looking for VoIP home phone, without needing to know anything technical or setting anything up.
I am in the Telecoms/IT business and even for me at home, I did not want to do any work, leave the setup / provisioning to the phone company, no hassle, IMO worth it for $4.95 per month.
