I've had some odd issues with VoLTE. I'm on 8.0.2 with Verizon and a 6+. The audio quality is great but the issue falls with call connections. If I place a call there is an unusually long period where the call is taking place. There's a long hand with the screen saying it's making the call (not yet a connection timer). Eventually is switches to a call connection and I've got people on the other end going, "Hello? Hello?"
I never hear ringing at all and, apparently, the other party picks up and has nothing until I eventually get audio.
When I'm in a 3G area the calls go through as normal. If I switch the LTE settings back to data only, things return to normal as well.
