why does my diaphone go straight to messaging
Welcome to iMore! So when someone calls you, it goes to messages? Do you mean the Messages app, or Voicemail?
If voicemail, try this:
1. Make sure that*iPhone?s Ring/Silent switch is OFF meaning ringer is ON.*A bell will flash briefly on the screen when you turn on the ringer.
2. Make sure that*the Do Not Disturb setting is not silencing calls (Settings > Do Not Disturb).
3. Make sure that Airplane Mode is OFF (Settings > Airplane Mode).
4. Make sure that your carrier software is up to date (Settings > General > About).
If it goes to the Messages app, try a hard reset:
Hold the top or side power/sleep button and the home button at the same time until the Apple logo appears, then release.
