I also switched to Vonage with the Linksys Adapter. I tried the following to get it to work with my Directivo2. (1) Tried all the codes *70 etc... with the internal modem. (2) Installed an external modem using hypter terminal to program it. (3) Had Vonage try every setting possible, spent an hour on the phone with them. (4) Had Vonage add a fax line and put the tivo units on them. Was able to get a little further but nothing really worked. Then I tried PPP on my two units and after playing around with the setup everything works great. Of course I have to have my computer on but it works everytime. Seem crazy that I had to buy the serial adapter from Weaknees and also the serial to ethernet adapter (guess its the same as buying an external modem) when my house it fully wired for ethernet and I have 2 USB adapters from my old Series 2 SA Tivo units. Why the network can't be made available is beyond me. So all I am saying is PPP seems to be the most stable approach (for the time being) for people with VOIP.
