My best friend had Vonage.. she (and I who talked to her MANY hors a day) Hated it. My roommate in his par of the house went to SunRocket ( think that is the name) ANohter VOIP thingie.. now the sound and such on that is amazing... I think it was a pre pay of 199 a year, and we dont see a big difference in the rate which we DL or anything on the network and his quility is far better than Vonage was.. my BF and her Boyfriend switched on his (the roomie) telling them how good Sun Rocket is. I saw a huge difference on my end (I my self refuse to go to VOIP, I like a real phone line). And they too saw a huge difference from Vonage to Sunrocket.
I think when the Roomie signed up he also got a free multi hand set phone from Vetach too heeh.. not a bad deal on his end for 200 bucks.
