I've been with vonage, sunrocket, packet8, voiceral, and have had nothing but problems. Vonage is tanking because they are having legal issues, plus their support is horrible. Sunrocket is a mess and keeps bringing stuff down, even their whole online system you can access. For days they couldn't be reached! While packet8 and voiceral had ok service when they were up, support was poor and the device they gave me was very low quality. They also couldn't transfer my number. When I made the switch to nitevoip they had my number transferred in 1 week no problems, I've submitted a few emails with questions and they were responded to within an hour, and the best thing is that their sound quality blows all companies I've been with out of the water. My ratings given with reasons: (sound quality: 4) because running over the internet sometimes my connection slows down and degrades an audio stream, the highest Id ever give a voip company is 4 (reliability: 4) if my power goes out or my internet is down I have no service so I guess it's not the most reliable out there, more reliable is a land line (customer service: 5) someone I can understand from the US through phone and email responses are super fast (features: 5) more features than most providers, all of them actually work unlike some other companies (price: 5) although nitevoip might be a few dollars more than some others, its also a few dollars less than some, anything a few dollars more or less is a great price when you're talking about any price thats atleast half of what I was paying a land line company (overall: try it and you will be very pleased, I know I am)
