I think I might have figured it out. I have a IMac, Ipad, Iwatch, macbook and Iphone. I have share focus modes on all of them. Last night I turned that off on all devices except the watch i forgot about. I kept testing the phone and had it going to user busy and voicemail. I turned celluar off the watch and wifi along with the DND mode was on and sleep mode was on. I depowered the watch so it couldn't connect and now my calls are going through. I tryed with 4 poeple who are all on my contact list so the question is what will happen with somone not on my list or a person not on favorites list. I think the focus mode on the watch is the problem. I haven't worn the watch in weeks its sits turned on by my nightstand. I have been wearing a garmin watch 90 percent of the time. thanks for all the help. I am going to hold off on a clear system backup for now and try this first. I but a new phone each year and my system data on the color bar is really small. I only have 76 gb of 256 taken in memory.

This is exactly what I am having. I went to the Verizon store and they tryed all these things and more and couldn't get it to work. I was told go to the apple store. At first we thought it was bluetooth and connection to my garmin watch or to my 3rd generation airpods. turned bluetooth off didn't make a diffrerence it still did it. This is the most frustrating problems I have ever had with Apple.

"Calls on iPhone 16 pro keep going to voicemail: My incoming calls keep going to voicemail and I do not have it set up to do so! Another fix for Apple please!"

Clear the Caches:

Clear the storage named "System Data" (formerly called "Other"). It basically contains unnecessary files such as caches that are used for system ease of use - all of which gather over time. And the iPhone just might have a few of these settings that need not be when they are. Here is how to rid of these: How to Clear "System Data" in your iPhone's Storage: - User Tips. Caches would be being used for remembrance of application use.
