HELP! I am missing calls while listening to music on my iPhone 5.

Question

Device: iPhone 5
Completelty upgraded to iOS 7.1.1
Apps set to automatically update
Carrier: Verizon
Location - Atlanta, GA
This use to happen occassionally, but has become a more frequent issue as of late. When I am listening to my music player or watching Netflix/Amazon on my phone I am randomly missing phone calls.
For example...just this morning, my wife called me and said "are you OK, I've called 4 times." My reaction was once again annoyance and disbelief because I was simply driving down the interstate listening to my music. The phone never stopped the music to answer the call on her first four attempts and then the call apparently went through on her 5th attempt.
This has happened at least once EVERY day this week. I have missed calls from my friends, nanny and most importantly about 10-12 calls from my wife.
It really does appear to be completely random because once this week my wife called while I was driving into work listening to my music and the call came through on the first attempt. My music paused, I clicked ANSWER...no problems at all. The call lasted a few minutes, we hung up, and my music automatically started back up. 30 minutes later she called me back, while I was listening to music and the call never came through to me. My music didnt stop, my phone didnt ring and I do not have a missed call on my call log. She however showed me her call log and sure enough it took her 4 times to reach me for that second call.
Sometimes it only blocks one attempt on her part...other times it can be 3 or 4.  Needless to say, this is becoming a very annoying issue.
I do not have the "Do Not Distrub" feature activated.  I have NEVER used that feature.  Here are the settings, which I presume are the default setting, under the DND menu:  Again, these must be the default setting because I have not touched them.  Ever.
Manual - turned off
Scheduled - turned off
Allow calls from - Favorites.  I do not have any "favorites" programmed into my contacts.
Repeated Calls - this is turned ON
Silence - this has "Only while iPhone is locked" selected.
Also, my phone will periodically, randomly tell me I have a voice mail but not make a noise and not ring at all.  Text messages are also being ignored.  No sound, no buzz, and then all of a sudden I get abanner notification of having a voice mail/text message.
Again, it works MOST Of the time with no issue. 
Any thoughts on this? 
Anyone else having the same issue?
Could this be a bug with iOS 7.1.1???
Thank you,
Ben

I skimmed through this very long post but from what I read, this sounds much more like a coverage issue with your network than a device issue.  I have not seen or heard of this issue before and I do not have this issue personnally and & I use the music app quite frequently while working in the yard.
The DND feature should not be a factor at all if you're sure it's turned off.  I always recommend restarting your phone by holding down the home button + the lock button for 10-12 seconds until the Apple logo appears.  Once the phone reboots, do a test to see if this has helped to resolve the issue.
If not, go to Settings > General > Reset > Reset Network Settings.  Then, test it out again.  Post back if neither of these solutions solve your issue.
