Calls straight to voicemail

Troubleshooting No Ring issues

Most basic first: Have you checked the mute switch on the left side of the phone above the volume buttons, and adjusted the ring volume with the volume buttons while viewing the Home screen? (You must be on the Home screen to adjust the ringer volume). 

If it rings but the ring isn’t loud enough: 

• First check the speakers. Go to Settings/Sounds & Haptics/Ringtone/Classic and tap Old Phone as a test. If it is loud enough then change it to whatever you want.
• Go to Settings/Face ID & Passcode, enter your passcode, and look at the switch for Attention Aware Features. When this is on sounds will be lowered when the phone sees that you are looking at the screen.

If there is no ring at all:

Are there missed calls in Phone/Recents on the phone? If they are not the problem is in the network, because the calls aren’t getting to your phone. Contact your carrier: 

• check with your carrier that they don’t have a local outage, and that you didn’t have any settings that would have immediately invoked voicemail, such as call forwarding.
• Note that they will still go to voicemail, because voicemail is prompted and recorded in the carrier’s network, not on your phone.
• check up on them at Down Detector - Crowdsourced outage checker

If they are in Recents here’s what to check in addition:

• Go to Settings/Phone. There’s a switch for Silence Unknown Callers. If it is on any calls from numbers not in your contacts will go directly to voicemail.
  • If you keep it on, in Settings/Phone make sure Dial Assist is enabled; it is needed to accurately match an incoming call to a contact.
  • Remember that banks, doctors and other professionals may not call you from the same number that you have in your contacts for them.
  • As some users have discovered, turning it on, then off sometimes helps.
• Also in Settings/Phone: Make sure Call Forwarding is off.
• Make sure Do Not Disturb is off:
  • iOS 14 & older: Go to Settings/Do not Disturb. Turn it off if it is on. Also turn off Scheduled. With both off none of the other switches there matter.
  • iOS 15: Go to Settings/Focus, and verify that all focus settings are disabled.
  • iOS 16 and later: Open the Control Center and turn off the button next to the word Focus.
• Go to Settings/Sounds & Haptics. Make sure there is a sound assigned to Ringtone.
• Go to Settings/Accessibility/Touch/Call Audio Routing and make sure Auto-Answer Calls is off.
• Go to Settings/Screen Time/Communications Limits. Tap each of the 2 entries and make sure both are “Everyone"
• Restart your phone-->Restart your iPhone, iPad, or iPod touch - Apple Support
• If all else fails, talk your carrier into replacing your SIM card (thanks to ASC user DShelbyD)

Maybe this will save someone else the hours of time I spent trying to figure out why calls from my home phone to my cell were routed directly to voicemail. After repeatedly checking my settings for days I was led to the Active Armor app which showed my calls were not allowed through to ring because of the false information it had that my home number was spam. When I corrected this misinformation manually, suddenly my calls went through without a problem.
