said by scots:I switched from VT to CallVantage, and have been very happy with CallVantage. One thing to note about CallVantage is that they give a $5/month discount if you're an AT&T Wireless customer, which brings the price down to $19.99/month. I've also seen people mention that if you don't have AT&T Wireless they'll still give the $5/month discount if you have some other AT&T service such as DSL or U-verse, but I've seen nothing on the CallVantage web site to verify that.
I have ATT (formerly Bellsouth) DSL and they do give the $5 discount if you have DSL with ATT.
