Only advice.....read details concerning E911 services. I'm not sure whether they have handled the problem yet, but up until recently, they could not provide E911 service to customers....at least to the person's local center. So, if you dial 911 and can't talk, you're SOL. I think that some companies may have addressed this, but it's something to check on if you are considering replacing your home phone w/ VoIP services.
