I just switched to Vonage from Voicewing because I wanted my Directv tivo to dial out, not to mention it is cheaper too. I have read a bunch of forums and found lots of different combinations of prefixes, call waiting options etc. None work. I have been able to get the tivo to dial and get to the point where it fails on negotiation. In only one place I found that this is because the modem speed is too fast and there is no way to slow it down. Please tell me someone here has got this too work and if you could post a link to or post the solution here. Thanks.
