Could be an issue where your phone isn't getting a good signal so calls are going to voicemail. If you don't think this is the case you can try rebooting your phone (hold the home button and the power button simultaneously until the Apple appears on the screen). Also just curious when you first started noticing this. I've seen people say this started occurring for them after they did the carrier update. If you feel like the issue may be the device and you're still under warranty you can contact Apple for support. They may direct you to Verizon if they determine the issue is network related.
kaebfly, thanks you for those great recommendations. I would like know if this is happening with certain people or is it sporadic? Do you notice this is happening when you are only indoors?
