iPhone 15 not ringing for incoming calls and going straight to voicemail
Why does my iphone 15 not ring when I receive a call and just go to voice mail?

iPhone 15, iOS 18
Some things to check:
The ring/silent switch on the left side of the phone. See the following Apple article: Use the side button, Home button, and other controls on your iPhone - Apple Support
Check the ringer volume at Settings > Sounds & Haptics > Ringtone & Alert Volume.
Settings > Phone > Silence Unknown Callers. See: Detect and block spam phone calls - Apple Support
Do Not Disturb. See: How to turn Do Not Disturb on or off on your iPhone - Apple Support
If none of the above, also try restarting. See instructions in: Restart your iPhone - Apple Support
