Sigh...sometimes I wonder if I'm writing in Esperanto because the replies I get indicate no one is actually reading what I write.
No, I don't have anyone set to go to voicemail. If I did, why would it mostly work? I was having trouble receiving calls before I rooted, after they updated the radio, after I rooted and flashed to CM7, and again after returning to stock. It doesn't ring when people call the Sprint or Google numbers. Sometimes the GV doesn't pick up the voicemail either; I get notified that my home Vonage number which GV rings as well has a message.
All of this was posted; sorry that you didn't bother reading all the words.
BTW, tonight at the movies, they have a kiosk where you can text Sprint and get a code for a worthless concession upgrades coupon. I sent the text to the Sprint number. And waited. And waited. Annnnnnnnnnnd waaaaaaaaaaaaaaaaited. 10 minutes later, the auto-reply came. Yay for instant communications.
