I was having this issue on an iPhone 8. Moved to an IPhone 11 and same thing is happening so it has to be from downloaded settings when I used iCloud to transfer. Do not disturb is not on. Call forwarding is not on. Callers are not blocked, it’s happening to all my calls including favorites and contacts. I have turned my phone off and back on. Help!
iPhone 11 Pro Max
Hello mallen0113, thanks for posting in Apple Support Communities. We understand that your phones calls go directly to voicemail after only one ring, and we'd be happy to help. Since you've already checked Do Not Disturb, Call Forwarding, and a few other things, we ask that you continue by checking for any third-party call-filtering apps and if "Silence Unknown Callers" is enabled. We'd also recommend that you check with your cellular carrier to see if a call-filtering service was applied to your account: Detect and block spam phone calls - Apple Support
Can you also go into Settings > Cellular > Cellular Data Options > Voice & Data and disable VOLTE? Once done, have someone call you to see if that helps. Check the cellular data usage on your iPhone and iPad - Apple Support
Aside from that, we recommend that update the iOS software and check for any carrier updates as well.
If none of those help, contacting Apple Support would be the next step: Apple - Support - Product Selection
Cheers!

Sorry for the troubles. Did you happen to try Resetting All Settings?
Likewise, did you happen to remove all the numbers in Settings > Phone > Blocked Callers? That may still be worth a test, even though your contacts are not in there.
Otherwise, yes, it may be a good idea to backup/erase and restore a fresh copy of iOS using a computer.
If it’s in fact an iOS issue and not a carrier issue, this should give you the answer.
I would typically set it up without restoring from a backup, just as a test. Because chances are if it continues it’s a carrier issue, and may require a new SIM card, or an adjustment on the account side.
Its unlikely this is a hardware issue, as this issue is normally not, and considering the same happened with your previous phone. So should be an issue with the software or carrier, but have been suprised before.
But before all that, I’d definitely reset all settings, which may just fix the problem, hopefully!
Restore your iPhone, iPad, or iPod to factory settings:
Hey mallen0113!
I know this started with your previous iPhone that didn’t have Face ID. However, I would check this setting, disable it and then test again:
About Attention Aware features on your iPhone X or iPad Pro:
https://support.apple.com/en-us/HT208245
You can navigate to Settings > Face ID and Passcode > Attention Awareness Features.
Can you disable this and then test the issue?
Oh well, was hoping it would be a simple fix! Can you turn on Airplane Mode for half a minute, (Settings > Airplane Mode), then off again and test?
I think other good steps maybe to take out/re-insert the SIM card, and/or even reset the network settings, (Settings > General > Reset), then test.
Likewise do you have any VPN’s or Profile’s or Device Managers installed in Settings > General?
Hope something helps!
Thank you so much for your assistance! I do not have any third party apps to filter calls installed and silence unknown callers is off. When I go into Settings > Cellular > Cellular Data Options > Voice & Data i see LTE and 4G. I changed to 4G turning off LTE but no change. All updates have been done. I worked with Apple Support via chat last night and was not able to resolve. Still searching…
I’ll call AT&T to see if they have any ideas. Not sure I mentioned that this started on my IPhone 8. I bought an IPhone 11pro max and st it up with my iCloud backup and the problem carried over to the new phone.
Hey again! Well done! Tough to say, is it all working normally again for every caller? If so, then yes, it was probably a server issue with the carrier (ATT) or the SIM card they provided and activate. Hope it goes smoothly from here on out! I know what it’s like to make and receive important calls, and they don’t work properly!
If still having troubles, let me, or anyone else here know!
Thank you so much for additional support! Tried turning on airplane mode and then off again. No change. During my apple session we reinstalled the SIM card and reset the network settings. I do not have any VPNs or device managers.
The only suggestion Apple had was to erase the phone and start over but since I just did that and it is still happening I am reluctant to do that again…
Well new twist! I went away for the weekend and was mostly out of the service area. On Friday morning I received a spam call that went directly to voice mail and just minutes later another one that rang through! I was so excited I answered! Tested with my daughter and friend and my phone was working. Long story short that only lasted a day and I’m back to all calls going to VM. I did reset all settings today and no change. I also removed a chunk of blocked numbers but not all. I’m thinking maybe I should go to AT&T and get a new SIM card and see what they say? Last effort before erasing my phone?
ah Yes I saw that suggestion on line and tried it last night to no avail. 🤷🏼♀️
iPhone rings once and goes to voice mail.
