Should get my Vonage box today and my number is supposed to switch over from at&t tomorrow. I like having a regular home phone for the kids, they are too young to operate a cell phone in a stressful situation, or give our address if they did manage to call 911. As soon as they get older I will happily drop Vonage and just go with our mobile phones.
But at&t is too expensive and less reliable than my internet service. Vonage will be almost half the cost and I expect it to be at least as reliable.
