I have had a few of occasions that my incredible doesn't ring but goes straight to voice mail. Not always from the same caller and not any common apps running that I can think of. The callers have told me they heard 5 or 6 rings and then got voice mail. I checked their phone entries and straight to voice mail is not checked. I had two of them call me right back and the phone rang. I am not using Google voice. It maybe too early to call it a problem but thought I would post to see if any others have had this happen.
