Well, never mind! I found the answer (no help from Verizon).
Go to Advanced Calling under Settings. Turn off HD Voice and Video Call.
Problem solved. Not sure why but it worked.
A previous post, Calls straight to voicemail, no missed call notification regarding a Samsung S6 having a similar issue found that turning OFF HD voice and video calling helped resolve the issue.
We certainly wouldn't want you to miss any calls. I see your most recent post indicates that you solved the issue by turning off HD Voice. Is that solution still working for you?

Usually, I have to restart my phone to get it to ring, and it doesn't happen every day. However, I turned off the HD Voice and Video Call setting, just as you said, and BAM, I instantly could dial my number and have it ring.
I can't believe Verizon techs don't know this trick after years of blogs!
Thank you so much!!
I called Verizon and explained what I did. They said it may have worked, but it is really only a temporary solution. Without that setting turned on, you can't talk on the phone and use internet at the same time. So, I turned it back on and was still able to ring the phone afterwards without having to restart it. It may just be a workaround that I will have to use on occasion. It's a pain to have to do it, but it's easier than restarting.
I also still have a Samsung S7. My 2nd one. Same habitual problem with both. Have to restart to to get incoming calls. I believe it occurs after using the Google navigation app. I've not been able to solve the problem.
