Google voice has been sort of flaky for me since I started using it. I use my old number, and I only use google voice for voicemail, I have it set up on my phone and in google voice. Sometimes if I decline a call they will get a verizon error message. And today out of boredom I called my cell phone from my work phone and it just rang...and rang...and rang....and rang...and voicemail never picked up. But then I got a notification from google voice that I had an 18 second long message which was completely silent. I did it again, same result. I logged into google.com/voice and confirmed that my greeting is set up. It's sad, because I love google voice. But if voicemail doesn't work then it has no value...I can't have people calling me hearing error messages or never getting to leave a message.
