I find the high rankings of VoiceWing to be a surprise. I'm on FIOS, and one of the reasons I stayed away from them and went for ATT CallVantage was that VoiceWing doesn't have many good reviews here at BBR. And in fact, many BBR reviews indicate call quality was not good.
reply to rmrper I had Vonage and Voice wing. I never had a problem with either. I left Vonage because I thought the ship was sinking. I left Voice Wing because I assumed that I would get all the features at around the same price. Guess what? VZ POTS is more $$ and less services than VZ Voice wing. I do believe Fios Phone (VZ Inhouse VOIP) is coming soon. VZ Voice wing I believe is outsourced. Lee
