i was having this happen on my first testing of the app. I found that after a while the light would just blink regardless of messages not being sent. I am hoping that google releases a little bit more info for us to use as they are now releasing apps for phones to take advantage of googlevoice. I noticed they are available for blackberry and android. Since android is open source(at least I thi k I remember it being soK maybe they will release the source so we can adapt it to our beautiful nokias Wishful thinking I know!
