Does anyone have any real and pertinent info from Apple/other users?
Two iPhone 5s models here, both on iOS 7.1. Carrier is Sprint. Unless DND or the mute switch or Airplane mode is on, our phones do ring, whether or not the phone is locked.
Something you might do is double-check everything carefully in Settings > Sounds that has to do with ringing. Beyond the obvious like making sure the "Ringer & Alerts" volume slider is up fairly far, as a test make sure "Vibrate on Silent" is on & call the phone. Also check the default ringtone -- a few of them are not very loud. I use classic > pinball because it is loud & its bright, treble sounds are easy for the tiny speaker in the phone to reproduce loudly.
A long shot to check is Settings > Phone. Make sure that somehow the number you are calling from is not on the "Blocked" list. Also, if it is in Contacts, click "Edit" & make sure it is either set to the default ringtone or one you know is loud enough to be easily heard.
