It's official. I stopped by the electronics store this morning and they can't get a new processor for the V portal. This sucks even more than usual because I'm in the middle of looking for new work, and it would help to have access to a phone.
I figured out that I can upgrade my account to get a desktop based system that links to my vonage number. This I've done - now I just have to find one of those microphone headset thingamabobs so I can test out the system and see how phone calls sound through the computer.
Keep your fingers crossed.
