When someone calls me my iPhone goes straight to voicemail, and when I receive a text, I get no sound letting me know one has arrived. I think I caused this when recently making some changes in "settings", but now I can't figure out what I did so I can fix it.
iPhone 4S, iOS 7.0.4
Do you have Do Not Disturb turned on? http://support.apple.com/kb/HT5463
You might want to read the iPhone manual to understand all the options that are available to you.

It's also available as a free iBook. If you install the iBook app, you can search for "iPhone user guide" to find it.
Why is my iPhone 4S going straight to voicemail instead of ringing?
