I just recently jump into band wagon and tried VoIP for the first time. I subscribed to Onesuite SuiteAdvantage (been using Onesuite as a phone card but not as voip) to see how big is the difference with the voice quality between voip and your regular land line. I was suprised that there's not much.
Been reading a lot lately about voip and other providers and I think Voip providers are differrent from each other. In fact, other people think Skype is just like Vonage but it is not because Skype is peer to peer while the other voip providers like Magicjack and Onesuite aren't and has their own systems where your calls passes through (well just correct me if I am wrong)
Anyhow, even though I am enjoying the quality and the savings of Onesuite voip, I don't think its enough to convince me to drop my regular land line altogether. I still don't want to risk what happened to SunRocket subscribers which they lost their phone service all of a sudden and their business were greatly interrupted.
