My Iphone 4 is not ringing and the phone is not muted or water damage! What can I do?

Clean the iPhone charging port with a clean dry toothbrush. This iPhone could be sensing it is connected to a dock due to shorting of pins, cleaning may help this.

In addition to what Brad suggested, think about going through the restart/reset/restore troubleshooting path. Perhaps a software issue or hung process...

In my case, the new option "Do not disturb" was activated automatically when I upgraded the phone to IOS 6. You can see a moon quarter at the left of the time in the basic screen if the option is turned on. Desactivating the option fix my problem. You can desactivate the option in "Settings" or you can change the settings in "Settings" then "Notifications".

Your left side switch is set to mute.
