I was thrilled that I could save money on my phone bill, but this system is down every other week. When it is working, the line if very loud and noisy. I worry that we will have an emergency and be unable to call 911 because our Vonage is down AGAIN! Getting someone to help takes a long time, they are nice and very polite, but expect to spend several hours (at least) turning things on and off and checking your computer settings with the tech support every time it goes down. I wish I had stayed with AT&T. Getting my phone number transferred to Vonage was such an ordeal, I have not switched back to AT&T yet because I don't have the energy for the transfer drama.
