Yeah. I've been using Vonage for the last several years. Faxes were hard to transmit and receive for a long time without errors, until I cleaned up the outbound data stream with one of those little VOIP packet optimizer boxes.
We're sweating it out here, because Verizon recently won a patent infringement case against Vonage. There's a temporary stay on appeal, but if Vonage ends up having to pay Verizon all those millions of dollars, and cease and desist with the operations due to the infringement, then we're toast. I'd like to say we could just switch to Charter VOIP, but who's to say they aren't infringing a Verizon patent, too?
