I got a Google Voice invite about a week ago, and while I mainly just wanted the voicemail perks, I went for the new number, just so I could have all the bells and whistles when I eventually need them. In the meantime, however, rather than let the account sit idle, I really wanted to figure out how to use the Voice visual voicemail for my Verizon line. I was on an iPhone for almost two years--I'm never going to go without visual voicemail again. But I'm not paying Verizon for it, the third-party apps I've tried all had enough annoying traits to drive me away, and hot damn, inaccurate as it may be, I want voicemail transcription if only for the comedic benefits of reading the mad-lib transcriptions of friends' voicemails. So, anyway, I finally stumbled across this post on the Google forums, giving a step-by-step procedure to redirect your missed/ignored/busy calls to your google voice account. (Basically, you make three calls using prefixes and your google voice number to set the redirects... the instructions also include all of the codes to undo all the redirects if/when you decide to go back to normal.) I tried it out, it took all 60 seconds to set up, and it works beautifully. Depending on how your voice account is set up, you may need to adjust some settings (so you don't get an email, text, AND google voice notification every time you get a voicemail, which I quickly discovered was quite annoying). Again, this only works if you have a Google Voice account, with a new number (but then, if you got GV for an existing number, you wouldn't have to go through all this). Don't know if anybody will find this helpful or not, but for me, it's a great way to get some functionality out of a very cool free service that would have otherwise likely just sat dormant until I finished grad school.
